A Scientific Commentary on Genesis 7:11

Rolf Bouma — Tue, 05 Feb 13 08:00:43 -0800

Genesis 7:11: In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened.

Genesis 8:1: But God remembered Noah and all the wild animals and all the domestic animals that were with him in the ark. And God made a wind blow over the earth, and the waters subsided; 2 the fountains of the deep and the windows of the heavens were closed, the rain from the heavens was restrained, 3 and the waters gradually receded from the earth.

The Flood narrative of Genesis 7-9 has played a prominent role in science and religion debates for over three hundred years and gave rise in earlier centuries to geological theories such as old earth catastrophism. While literary studies have uncovered the chiastic structure of the Flood story (see Gordon Wenham, “The Coherence of the Flood Narrative” Vetus Testamentum 28 (1978):336-48) and with it the theological pivot point of the entire narrative (Gen. 8:1 – “And God remembered Noah…), much of the popular attention remains on the questions regarding details (Is there THAT much water in the world to cover ALL the mountains to a depth of 15 cubits? Could you really fit two or seven of every animal species in an ark that size?)

Looking at a smaller matter, we find at the beginning and the middle of the narrative indications of an ancient Near Eastern worldview. As the story is told, the flood was not merely the result of excessive rain, but actually the convergence of the waters above the earth with the waters below the earth. It is, as one translation puts it, as if the sluice gates at the deep and of the heavens were thrown open and water poured in from above and below. This is a consistent picture from the Old Testament of a three-tiered universe—a dome above the earth holding back the heavenly waters, a flat earth with water on its surface, and water under an earth which is held up by pillars.

That the story is told using the cosmology of its time should not be unduly unsettling, nor that the story is reinterpreted as new understandings of the universe come into favor. By way of example, consider John Calvin and his understanding of the structure of the universe. Although committed to the principle of sola Scriptura, Calvin recognized that the Bible would have been written in terms its original recipients would have understood.

Calvin inherited the medieval cosmology of his time, a way of viewing the world heavily influenced by Greek thought and one which was about to receive shocks from astronomers such as Copernicus and Galileo. But not just yet. Calvin still subscribed to the common conception of his day in which the four elements—earth, air, fire, and water—comprised the earthly sphere and possessed unique characteristics. The nature of air and fire was to rise, while the nature of earth and water is to sink. Earth, being heavier than water, should sink to the center of the cosmos and water should compose the next layer. Both earth and water are spherical, i.e., naturally form spherically around the cosmic center. Thus the heavier spherical element of earth should be encased entirely within the lighter spherical element of water.

Notice what this does to the flood story. For Calvin, the amazing thing is that the world isn’t constantly under water and subject to flooding. In the cosmology of Calvin’s day, it does not take an act of God to cause a universal flood, but rather an actively present and restraining hand of God to keep the waters back in everyday circumstances and make inundation by water something other than universal.

Obviously, Calvin was wrong. Or perhaps we should say that medieval cosmology was flawed and justifiably gave way to new conceptions of the universe. The answer is not to return to an ancient Near Eastern cosmology, but to reinterpret cautiously within new and better cosmologies and to pay closest attention to the text and the theology of scripture.

The geological and planetary sciences bring their own unique contributions and are of more interest than the latest expedition to discover the ark on Mt. Ararat. Is the flood story a universalization of a catastrophic regional event that burned itself into the psyche of ancient cultures in the Mediterranean basin? Various theories regarding a Black Sea venue for a catastrophic flood event are still in process of being sorted out. It’s intriguing. Or the question where the water on Planet Earth comes from? Was it always here as an emanation of vapors from the earth’s crust in its early formation, or has it accumulated over eons through the steady bombardment of earth by small, icy comets? It’s an intriguing scientific question that is in the midst of determination through testing.

Preaching Suggestions

When preaching on the story of the Flood, it is easy to get lost in the debates over particulars. As mentioned elsewhere, to tackle all the peripheral issues threatens to turn a sermon into a geology lecture. Other settings are better suited to addressing those questions, and those are best addressed open-endedly.

A brief explanation of ancient Near Eastern cosmology can be helpful to contextualize the story. If there are those who are tempted to think that a cosmology embedded in the Bible must be inspired and definitive, one can note that cosmology has changed by the New Testament. The Bible itself isn’t wed to a particular structure of the universe.

What is important is to keep the theology of the text front and center, and in that theology there are at least three non-negotiables from the flood narrative. First, human sin and violence threatens to undo a good creation (the flood is a de-creation event, a return of the waters mentioned in Genesis 1:2). Second, God remembers Noah, and never forgets his promises. Third, the end of the flood is a covenant with the whole earth regarding the stability and endurance of the natural order.

Series: It's an Old World After All

Joy Walters — Tue, 06 Nov 12 07:00:44 -0800

In our last Videocast, we explored some of the ways scientists have been able to determine the age of hominid fossils. Today, in our sixth BioLogos videocast, we extend the question to the age of the Earth. The first section, featured today, explains four methods scientists have used to determine that age: tree ring, lake varve, radiometric, and seafloor spread dating.

The script was written by biology student Joy Walters, with help from BioLogos president Darrel Falk.

Series: Biblical and Scientific Shortcomings of Flood Geology

Gregg Davidson, Wolgemuth, Ken — Mon, 17 Sep 12 05:41:28 -0700

This is the first in a four part series taken from Gregg Davidson and Ken Wolgemuth's scholarly essay "Christian Geologists on Noah’s Flood: Biblical and Scientific Shortcomings of Flood Geology".

As Christians and geologists, we frequently encounter people with stories of storm tossed and shipwrecked faith that started when they began to wrestle with apparent conflicts between science and the Bible. The stories have a common thread. The Bible, they were told, clearly teaches the earth was created a few thousand years ago with life forms fashioned more or less as we find them today. Because the earth is very young, the incredibly complex sequence of rock, sediment, and fossils found on our planet must have been deposited in a very short period of time. Noah’s Flood, as the only plausible causal agent, was obviously a global and violent event. Theories of an ancient earth and adaptation of life forms, they were further informed, have been constructed on flimsy evidence created by atheistic scientists searching for ways to expunge God from modern culture. But as these sojourners began to explore and understand the actual evidence for an ancient earth, they found themselves increasingly convinced of its legitimacy, and thereby increasingly questioning the veracity of their faith – many to the point of relegating Christ to just another wishful myth.

It is our conviction that these stories of strained or lost faith derive not from an inherent unwillingness to trust the Bible, but rather from misguided teaching on the message of Scripture. Those insisting the earth is young are not simply putting their faith in God’s Word, they are putting their faith in their own particular interpretation of that Word. As such, an entirely unnecessary stumbling block to faith is created, where faith in Christ first requires rejection of sound science.

As we have prayed and studied this subject, we have felt God’s call to speak out against this misplaced stumbling block. We are sensitive, however, to the fact that when scientists speak on issues of faith, there is a natural suspicion that science will be regarded as the ultimate arbiter of truth, and Scripture will have to yield whenever conflict arises. It is thus important for us to state here that both of us ascribe to the authority and inspiration of Scripture, the reality and necessity of Christ’s death and resurrection, the existence of genuine miraculous events, and the truthfulness of the Biblical historical narratives. In our understanding, science will never trump Scripture, but by virtue of science being a study of God’s natural creation, it may occasionally assist in our understanding of God’s written Word. Where this has occurred historically and has been accepted by the Church, the invariable result has been the abandonment of an interpretation of some secondary importance, without any change in our understanding of the intended central message.

This phenomenon is illustrated well by the 17th century clash between Galileo’s claims that the earth revolves around the sun, and the multiple passages in Scripture that appear to clearly present a static earth as the physical center of God’s natural creation. The Bible tells us repeatedly that the earth is fixed upon its foundations (Ps 93:1, 104:5) and the sun rises and sets (Eccl 1:5, Ps 19:6). Within the context of the historical narratives (which we are not accustomed to interpreting in any figurative manner) we read statements about “the sun rising over the land” (Gen 19:23), and a miraculous event during a famous battle where “the sun stopped in the middle of the sky and delayed going down a full day” (Josh 10:13). Likewise in the Levitical law, we find commands to complete the Passover sacrifice “when the sun goes down” (Deut 16:6).

God’s people had interpreted these verses for thousands of years to be authoritative statements about both spiritual and physical realms, and 17th century believers understandably struggled with allowing science to alter traditional interpretations. If God says the sun rises and the sun sets, how could it be otherwise?

Fast forward a few centuries, and we are now somehow quite content to have allowed science to alter our thinking on these verses, without abandoning notions of inerrancy or inspiration. The reason is simply because it was eventually recognized that the primary message of these verses was never on the nature of nature, but on the nature of man and his experience with his environment and his God. Solomon and Joshua accurately recorded their experience from an earthly perspective (sun rising and setting), and David praised God for holding the earth fixedly in His hand (Ps 93:1, 104:5), without requiring a meaning of fixity in space. The central message of these verses was apparent to readers before and after Galileo. Only a secondary interpretation, likely never intended by the writers, was cast off after scientific advances.

So what is the issue regarding Noah’s Flood? The modern debate centers around two questions. Was it truly global in extent, and can the Flood account for the earth’s complex geologic record? To address the first, it is worth being reminded of the Apostle Paul’s letter to the church in Rome where he makes a statement that “your faith is being proclaimed throughout the whole world” (Rom 1:8). Entire people groups existed at this time in China, Australia, and North and South America who knew nothing of the church in Rome. Though using wording that literally means the entire world population, Paul is clearly referring to the world known to him and his readers at the time.¹ Paul speaks truthfully from his experience. Allowing for the possibility that Noah’s Flood encompassed all of known humanity without necessarily covering the entire planet is thus consistent with how other passages in Scripture are interpreted by Christians who believe the Bible is authoritative and trustworthy.

Our primary interest in this blog series is the second question, the widely promulgated notion that the Flood can account for the earth’s complex geology, and that all genuine Christians should accept this viewpoint.

Notes

1. Many Biblical scholars define a literal interpretation as one that takes into account the literary genre, figures of speech, context, and author/audience perspective in deriving the intended meaning. By this definition, poetry and allegory are literally interpreted as figurative. In this blog and in our article, our use of literal conforms to its more common definition where a literal interpretation is one that adheres to the precise definition of words without figurative meaning and without requiring additional context to understand.

The Questions Update: The Age of the Earth

Sat, 14 Jul 12 05:02:55 -0700

How are the ages of the Earth and universe calculated?

In a Nutshell

Many independent measurements have established that the Earth and the universe are billions of years old. Geologists have found annual layers in glaciers that can be counted back 740,000 years. Using the known rate of change in radio-active elements (radiometric dating), some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.6 billion years. Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years. The expansion of the universe gives an age for the universe as a whole: 13.7 billion years old.

In Detail

Introduction

Astronomers and geologists have determined that the universe and Earth are billions of years old. This conclusion is not based on just one measurement or one calculation, but on many types of evidence. Here we will describe just two types of evidence for an old Earth and two types of evidence for an old universe; more types can be found under Further Reading. These methods are largely independent of each other, based on separate observations and arguments, yet all point to a history much longer than 10,000 years. As Christians, we believe that God created the world and that the world declares his glory, so we can’t ignore what nature is telling us about its history.

Age of the Earth from seasonal rings and layers

If you’ve ever seen a horizontal slice of a tree trunk, you’ve seen how a tree forms a new growth ring each year. In years of drought, the tree grows less quickly so the ring is narrower; in good growing seasons the ring is thicker. A tree’s age can be found by simply counting its rings. By comparing the pattern of thick and thin rings to weather records, scientists can verify that the method is accurate. This method can even be used on dead trees that fell in a forest long ago. For example, the last 200 rings in the dead tree might match up with 200 rings early in the life of the living tree, so the two trees together can count back many years. In this way, multiple trees can be used to build a master chronology for a forested region. European oak trees have been used to build a 12,000-year chronology.¹

The annual ice layers in glaciers provide a similar method that goes back much further in history. Each year, snowfall varies throughout the seasons and an annual layer is formed. Like the tree rings, this method can be verified by comparison to historical records for weather, as well as to records of volcanic eruptions around the globe that left thin dust layers on the glaciers. Scientists have drilled ice cores deep into glaciers and found ice that is 123,000 years old in Greenland² and 740,000 years old in Antarctica.³ These annual layers go back much farther than the 10,000 years advocated by the young earth creationists. The Earth must be at least 740,000 years old.

How can an old Earth be reconciled with Genesis? See Scripture Interpretation

Age of the Earth and solar system from radiometric dating

In your high school science classroom, you may have seen a large poster of the periodic table hanging on the wall. The periodic table shows the types of atoms that make up the world around us. An element in the periodic table can come in different flavors called isotopes. Some isotopes are unstable, and over time these isotopes “decay” into isotopes of other elements. For example, Potassium-40 is unstable and decays into Argon-40. As time passes, a rock will have more and more Argon-40 and less and less Potassium-40. Radiometric dating is possible because this decay occurs at a known rate, called the “half-life” of the radioactive element. The half-life is the time that it takes for half the radioactive sample to change from one element into the other.

Some isotopes have short half-lives of minutes or years, but Potassium-40 has a half-life of 1.3 billion years. Radiometric dating requires that one understand the initial ratio of the two elements in a given sample by some means. In this case, Argon-40 is a gas that easily bubbles out and escapes when it is produced in molten rock. Once the rock hardens, however, all the Argon-40 is trapped in the sample, giving us an accurate record of how much Potassium-40 has decayed since that time. So, if we find a rock with equal parts Potassium-40 and Argon-40, we know that half the Potassium-40 has decayed into Argon-40, and that the rock hardened 1.3 billion years ago.⁴

It’s hard to find rocks on the surface of the Earth that have not been altered over time. Most old rocks have been eroded by wind and water or submerged by continental plates. The oldest reliably dated rock formation is in Greenland, where several different isotopes were used to find an age of 3.6 billion years.⁵ Scientists also recently dated zircon grains (which resist erosion) in Western Australia to 4.4 billion years old.⁶ To find older rocks that haven’t been eroded, we need to look beyond Earth. Meteorites are rocks from the solar system that have fallen to Earth recently and haven’t suffered much erosion. Their pristine interiors give an age that dates back to their formation at the beginning of the solar system. Nearly all meteorites have the same radiometric age, 4.56 billion years old.⁷ Thus, the solar system, including the Earth, is about 4,560,000,000 years old.

"Centered": The Language of Science and Faith

Karl Giberson — Fri, 18 Nov 11 05:56:02 -0800

In a recent interview with the Sirius XM radio show Centered, Karl Giberson, co-author of BioLogos' The Language of Science and Faith, sat down with host Don Belanus to discuss the book and the interplay between science and faith. Among the topics they cover are what constitute the "genuine questions" of science and faith mentioned in the title and whether the age of the earth should be a top priority for pastors to discuss with their congregations.

Seeing the Flood Story Through an Ancient Israelite Lens

Pete Shaw — Sat, 12 Nov 11 04:00:15 -0800

Though some may believe that moving the science/faith dialogue forward is best left to scientists, scholars, and theologians, we at BioLogos recognize that our pastors play an invaluable role in the conversation. Across the globe, pastors are helping their congregations work through difficult issues of science and faith with honesty, insight, and a gentle spirit. To this end we present an ongoing series recognizing sermons (and the pastors who give them) that are helping to promote the harmony of science and faith. Today's sermon features Pete Shaw, who is the senior pastor of Crosswalk Community Church in Napa California. The full sermon can be downloaded here. Finally, if you know a sermon or podcast related to science and faith that has especially spoken to you, please let us know.

The early chapters of Genesis appear to pose scientific problems that challenge our literal, post-Enlightenment lens through which we often read the Word of God. (See this post for a commentary on how this situation came about.) This leads many people to believe that the descriptions in these texts are meant to reveal more than raw scientific fact. Pete Shaw of Crosswalk Community Church highlights the story of Noah and the Ark to explore the possible reasons for adopting a non-literal understanding of this ancient narrative. Shaw first summarizes the story of Upnashatim in the Epic of Gilgamesh, a famous Sumerian flood story that the young and old in Abraham’s day would have known well. Upon comparison, these two accounts—the Genesis flood and the Gilgamesh flood—are incredibly similar. Furthermore, Shaw exposes the various practical problems that arise if one takes every word of the Noah story to be a precise truth. For example, he wonders how Noah could have fed and maintained every living land creature in a small boat for ten months. He also explains how a primitive understanding of the universe is heavily reflected in this text. In light of these points, he concludes that whether or not this story is portraying actual historical events, it is presenting rich truths about God, and that should be the focus of the believer.

Transcript

“The first eleven chapters of Genesis are what scholars call pre-history. In other words, they can’t really date what was going on very well in those first elven chapters. After that, twelfth chapter on, it is a lot easier to date, and the stories have a different feel, a different structure… but those first eleven have caused a lot of debate over the years. In fact, the next slide is going to kind of give you the line of where I am going to take you today. You might not be aware of this, but there is a Noah controversy. You and I, when we hear the story of a great flood, the first thing that comes to our mind—when we think of the whopper of all whoppers—we think of Noah and the Ark, but if we lived in Abraham’s time or especially before, the name Noah probably would not have come up. In fact, if we grew up with Abraham, the story we would have most likely known about was the story—I am going to butcher this name—of Utnapishtim.

You are familiar with Utnapishtim aren’t you? And you are familiar with the god Enlil. I am sure you are familiar with Enlil. And you would have been very aware of a storybook that was read by children and adults alike called the Epic of Gilgamesh. And in the eleventh tablet of the Epic of Gilgamesh, we have the story of Utnapishtim and the god Enlil. And just so that you would know about that story a little bit, knowing that that would have been the predominant story that you would have understood anytime you thought about a flood, this is how the story went down. So, this god Enlil was the god of thunder and rain and all that and he was not a happy camper (kind of temperamental) as thunder gods can be. And for no clear reason, except to mess around with some of the other gods in his discontent, he made the decision that he was going to wipe out the earth with a great flood. And one of the other gods, a goddess in fact, did not like that this was going to happen and thought that it was unfair, unjust, and so she sent a message to Utnapishtim that this flood was going to come at the hand and the wrath of Enlil. And so Utnapishtim got to work, and he built a vessel (a strange vessel), a cube, but he used some of the similar materials that we saw in the Ark, and he made this massive structure (if in fact you do the math, it is probably at least twice, if not much larger, than the actual Ark) this massive cube that he made hoping that it would float, and he got it done on time.

The rain didn’t come down for forty days, it came down just for seven, but it flooded everything out, and the only survivor was Utnapishtim. And when Enlil came around and saw that some human beings had survived, he was very upset because he intended to wipe out everybody to show his wrath and his anger to the world and to show that he was upset to all the gods in heaven. Well, Utnapishtim obviously saved his own life, the life of his family, the life of his personal animals because those are the animals that he saved—not the rest of the animals of the world. And he took some carpenters along because he didn’t know how to build stuff and once you are starting over you have got to build stuff, and so he brought some carpenters along. In honor of his faithfulness (in light of this word from the goddess) he was given divinity. And so, he became a god, he became one of the gods, he got to reside in heaven, if you will, because of his faithfulness…interesting story.

If you grew up in Sumer, which is present day Iraq, and you grew up with Abraham in what is present day Baghdad that would have been the story that you would have known very, very well. It is because that story exists and other cultures have their own flood stories as well that some scholars look at the story of Noah and the Ark, and they think, ‘well, gee, how should we really interpret this thing? You know, our Enlightenment and post-Enlightenment perspective says it is in black and white, and if it says that is what happened, then that is exactly what happened. There is no way around it.’ Well, what if the first people who shared this story with each other and what if the early writers of this word, what if when they approached the Bible, they didn’t approach it the way we do? What if they didn’t approach the Bible, the Word of God, as a literal, this is exactly how it happened book that our post- Enlightenment eyes are framed to do? How would that change us? And also, some of the things that some of the challengers of this story are bringing out are some of the issues with the story like ok is this really a big enough boat to handle all of the creatures of creation…can they really, really fit?

Some have really tried to make a case that there weren’t as many animals back then as there are now because they got together and hooked up, and now, we have all kinds of varieties and that kind of thing. And so that is kind of there, but you are talking ten months of time! How do you feed all the animals of the world? How do you store all the food? Did they eat fish, because the fish didn’t die? The fish lived on just fine. How do you do that? And what about—it is kind of unpleasant—but all the excrement? What are you going to do with all that ‘bleep?’ Are you going to throw it out the eighteen inch window at the top? Did they have a conveyor belt system? How did it work? And so they look at that and think, ‘I am just not sure about that.’ Would you really take that literally? Is that how we should take it? Is that how they took it around their campfires and around their dinner tables? Did they think about it that way?

And there are other issues too that academics look at, and they challenge somewhat. Like they know that forty days and forty nights is a proverbial statement in Jewish culture. It was like saying (and you see it in many accounts in the Bible), forty days and forty nights was saying a long time, but it probably was not meant to be taken literally. It is just a long time. It is how they thought about things. Then, there is the issue of the rain itself, and how it all came down. Now, the New Living Translation and most modern translations, just simply talk about it as--there is the sky and the rain came down from the sky and you are good to go. But there is another word that is used. If you go to the New King James Bible, for instance, and they talk about the firmament—that the rain came down from the firmament. And so, when we think about firmament, we think, ‘well they are talking about sky or they are talking about the starry host and all that stuff,’ but if we go back to the original word, which the New American Standard version got right (it is one of the most academic and precise versions that is out there), both in the creation story and in the Noah account, they use a different word for sky: they use the word dome.

Now, I am going to butcher this a little bit, but broad stroke version is that the way the ancient people saw the world was that we kind of lived in this bubble, you know sort of like a snow globe, and there was water--not all inside, but outside, surrounding us. There was water below and there was water above, and above us was this massive dome called the firmament or called the sky. And then when it rained it was because God was opening up the floodgates of heaven. That is how they thought back then. They didn’t know any better. And so, kind of what these questions are asking us now is how we make sense of this and do we have to believe like they did in order to believe the story. How many of you believe that the sun revolves around the earth? None! Nobody does. Do you get mad at, do any of you hold a grudge against the earliest people in the Bible, actually, all the people in the Bible, do you hold them accountable and are you angry at them that they believed with everything in them that the sun revolved around the earth and not the other way around?... no, of course not. Do you get angry at them because they believed we lived in a dome and that God opened up the gates of heaven and there you go? No, you don’t hold it against them because you understand that it is the best that they could do given their time.

But we live in the age of Doppler radar, right? We know within minutes, you know, when rain is going to hit Napa and when it is going to move on to Valeo, and so on and so forth. I mean it is that precise, and we know when it is coming hundreds of miles off shore and we can look thousands of miles because of satellite stuff and our ability to understand temperatures and all that. We know how the whole thing is brewing. We know that hurricanes are lining up one after the other in hurricane season because we have cameras up there that are seeing them start to form, and we can gauge temperature in the water and so forth—we do not live back then. So, it would be inappropriate for us to become primitive in the sense of looking at the world the same way they did in that kind of a literalness because we know different, you know what I mean? We know different. And so really the bottom line is that the literalness of the story really isn’t the most important thing to begin with anyway.”

A few editorial reflective thoughts by Darrel Falk: The sermon continues, of course, and you can download it at the above link. What is "the most important thing" to which Pastor Shaw refers as the audio clip draws to a close? Regardless of whether you think it is historical or not, what is the message that God wants to communicate to us through this story? Consider reading Genesis 9 right now. What are the parallels in this "recreation"account to the original creation account? What does God want us to see in making those parallels? What about the rainbow? What does it symbolize for you? Can you sense God's love for all of creation (not just humankind) as this story draws to a close? Why does the story of Noah himself, however, not have a happier ending? Have we seen the theme of nakedness and the need to cover up nakedness in an earlier scriptural passage? Why do you think the story of Noah draws us back to this point (nakedness and shame), just like the story Adam and Eve does? What brought on shame for them? What brings on shame for us? Do you see that God is wanting us to think deeply about this story and its meaning? What is another example of the need to cover up? (Hint: think Moses.) What difference does the coming of Jesus make to all of this? (Hint: see II Corinthians 3:12-18.) Do you see the rainbow?

Navigating the Crises

Brian McLaren — Wed, 21 Sep 11 09:11:52 -0700

Today's video is courtesy of filmmaker Ryan Pettey, director/editor of Satellite Pictures.

In this video, author and pastor Brian McLaren discusses the idea of surrogate arguments, in which a debate over one thing is really a means for arguing something completely different. According to McClaren, the argument over the age of the earth is one such example, in which an apparent scientific debate is actually a discussion over the nature of religious authority and how previous generations have understood how we should interpret the Bible. Such debates can lead to two crises: one of confidence and one of ethics. While some have the confidence to differ with the views of the generation that raised them in the faith, McLaren points out that some are not able to overcome the ethical challenge of differing with grace and love. When this happens, he notes, the end result is damage to the Church and a retrenching of the views of the older generation. Managing the crises well requires courage of convictions while also respecting tradition and maintaining a gracious spirit. Anything less, is not only unwise, it is also unfaithful.

God's Use of Time

Matthew Blackston — Fri, 19 Aug 11 05:00:43 -0700

I can still recall the first time I encountered a man performing as a living statue. His costume, body paint, and utter stillness made him very convincing. I also recall the eerie feeling I experienced upon first seeing him move. Ordinary statues are, of course, static, but if you hang around a living statue long enough you’re bound to see it move, if only to blink its eyes. I find that when many Christians think about the way God created our universe, our planet, and the forms of life that dwell on it, they often bring a static expectation similar to what we bring to an ordinary statue. It’s as if we assume the physical realm were merely a rigid three-dimensional sculpture, immovable with time.

But since time exists, change and development are possible. The sciences have acquired the tools to “look back” in time and explore our universe’s rich history, so we know that the universe and the life in it do indeed evolve. Through these observations in the natural realm, it’s difficult to avoid the conclusion that God typically prefers to do His work gradually rather than instantaneously. In what follows, I’d like to briefly explore some of the ways that our universe has been and is evolving over long periods of time and attempt to show that the concept of a God who makes use of long timescales ought to be familiar to us from the story of redemption in scripture. And like observing a living statue, by staring long enough (in this case millions and billions of years) we are able to see a world that is moving and changing, which hopefully deepens our appreciation for the wonder of God’s dynamic creative acts.

God’s use of time in the physical realm

The sense of enjoyment that comes from studying the dynamically evolving universe that God has created is similar to that of a gardener when he or she watches a seed grow into a mature plant. And when considering the history of the cosmos, the analogy of a seed in a garden is an apt one, with each branch of science reinforcing and corroborating the story that is told.

From physics we learn that all the matter and energy that now exists in our universe originated in a hot, dense state (something akin to a primordial seed) which burst forth and has been expanding and cooling ever since. Myriads of stars have gone through the process of forming, burning, and dying, with many exploding in what's called a supernova. These long stellar life cycles have been going on for billions of years and are responsible for "cooking up" and dispersing all the atomic elements necessary for forming planets like Earth and creatures like us.

Once our planet formed, we know from geology and its theory of plate tectonics that the earth's crust has been in a constant (but very slow) process of moving and changing, shifting even the continents around over many millions of years and forming majestic mountains, islands, and other geological features. The picture becomes even more fascinating when biology enters the landscape, describing how life has slowly developed, also over many millions of years, beginning from the simplest of organisms and progressing all the way to beings like us, of such complexity that we are able to reflect on and enjoy the entire display.

But how do we know all this, since our short lives don’t allow us to see these long drawn out processes in action? I see these same sciences as a great gift from God that allow us to explore beyond the bounds of our own time. For instance, when astrophysicists look up into the night sky, they see light that has taken millions or even billions of years to reach us, meaning that they are literally looking at what our universe looked like in the distant past. Geologists look back in time by studying layers of rock, sediment, or ice. They have even found evidence that the earth's magnetic field has flipped many times over the course of the Earth's history so that even the direction our trusty compasses point isn’t constant! Biologists have the fossil record and genetics as a means of exploring the rich and fascinating history of life, teaching us about the ancestors of modern humans as well as exotic creatures such as dinosaurs. All around us the physical world is shifting, changing, and unfolding in an extraordinary way, teaching us that God, the ultimate Gardener, is pleased to watch his creation grow and mature gradually.

God's use of time in redemption up to Jesus

A good number of Christians find the idea of God using long maturation times in creation threatening to their understanding of scripture. But what we learn about God from scripture is not inconsistent with a God who works over long timescales. We see this if we look at the grand meta-narrative of the entire Bible, of which I’ll cover a few highlights to demonstrate my point.

After humans made a mess of their intended role in the created order, God desired to restore it and put it right. And like what we learn from the sciences about the evolution of the universe, He decided to take his time about it. God began his redeeming work with a promise to use Abraham's family to be a blessing to the entire world (Gen. 12:1). This was a promise that was ultimately fulfilled in Jesus nearly two millennia later. Now if God had been in a hurry, he might simply have allowed Sarah to conceive by the Holy Spirit and bring forth Jesus directly. But instead, he decided to take the scenic route, working through Abraham’s seed, including Jacob, Moses, David, and others until the time was right for Jesus.

As time went on and God’s people developed into a nation, David rose to the throne and God made another promise -- that of perpetual kingship to David’s line (2 Sam 7:13). This was another opportune time for Jesus to be born, take the throne, and fulfill the promise. But again we find God taking his time, allowing the kingdom to be divided and eventually conquered, and God’s people sent into a long exile, until the time was right for Jesus, nearly a millennium after David.

God's use of time in redemption after Jesus

The Christian faith holds that in the “fullness of time” (Gal. 4:4) God sent Jesus as the individual in whom all the promises of God ultimately converged. Just as God's physical creation developed slowly and eventually brought forth our earth and life and humanity, so God's purposes slowly unfold and culminate in Jesus, the descendant of Abraham and David who becomes the blessing to the world.

But here again is another case that demonstrates the point I’m attempting to make. Even the blessing that Jesus comes to announce and inaugurate develops slowly and dynamically – God, the Gardener, continues to slowly cultivate. Jesus himself teaches us to expect this to be the case in parables about the kingdom such as that of the mustard seed (Mark 4:30-32). Thus, the world isn’t automatically cured of its ills after Jesus’ resurrection. Both then and now, evil, sin, and injustice still exist and there is much that remains to be redeemed. The church is called to continue living in this meta-narrative until we reach the second climax: when Jesus reappears and ushers in the fullness of the new heavens and new earth.

A similar point can be made about God’s redemptive work in the lives of individual Christians as well. God forms each of his children over time through our relationships, our experiences, the trials we encounter, and the service we render. “I am the vine, you are the branches”, says Jesus in John 15:5. God is “growing us” as individuals and as every Christian knows from experience, the maturing process often seems very long indeed.

In conclusion, this brief survey has shown a consistent picture of how God works in his creation. In the cosmos, in the evolution of life, in the redemption of the world, and in the redemption of individuals, God sees fit to use long timescales for accomplishing his purposes. Moreover, with the similarities between what we learn of God from nature and from scripture, Christians needn’t react defensively to what science tells us about the history of the cosmos. Instead, we can indulge in the opportunity to marvel at the ever continuing work of God the Gardener, both in His dynamic creation and His dynamic acts of redemption.

Adventist Origins of Young Earth Creationism

Karl Giberson — Mon, 25 Apr 11 17:36:54 -0700

Many evangelicals believe that Young Earth Creationism is the only authentic, biblical way for Christians to understand origins, and that until the advent of Darwin's theory of evolution, it was the only view held by Christians. However, in this excerpt from Saving Darwin, Karl Giberson explains that Young Earth Creationism's origins are surprisingly recent.

Christian Geologists on Noah’s Flood: Biblical and Scientific Shortcomings of Flood Geology

Gregg Davidson and Ken Wolgemuth — Mon, 25 Apr 11 17:09:05 -0700

Geologists Davidson and Wolgemuth address the widely promulgated notion that the Flood can account for the earth’s complex geology, and that all genuine Christians should accept this viewpoint.

When Appearances Are Deceiving

Rev. Scott Hoezee — Thu, 03 Feb 11 11:32:56 -0800

“That just doesn’t sound right.”

At one time or another, we have all had this reaction to something someone said to us. Usually what we indicate by saying this is that we sense intuitively that something is amiss in what was just communicated to us but we cannot at the moment lay our finger on just what that “something” is.

Ever since I was a kid, that was my gut reaction to those well-meaning people in my church and school who told me that despite what many in the sciences were saying, the earth and the entire universe were actually of relatively recent manufacture (say, on the order of 10,000 years of age or so). Yes, there are rocks on the earth that test out to be millions of years old but you must understand: all of those things popped into existence in one fell swoop already bearing the marks of a certain age. God created the universe in motion with the appearance of age. It looks old but it isn’t. Already on his first night in Eden, Adam was able to see stars that we can now measure to be so far away that their light would take millions of years to get here. But because God created things already in motion, that light hit Adam’s eyeballs immediately even though the universe was a scant six days old.

That never sounded right to me, but one could conceive of it. Doing such a thing would hardly be beyond an almighty God’s abilities. God could snap his fingers and create any state of being he wanted. Still, something about the whole “appearance of age” scheme nettled. After all, what God could do cannot trump what a loving and true God would do.

My “Ah-Ha” moment that confirmed my intuition that something was wrong here came a few years ago when my colleague, Deborah Haarsma, gave a guest lecture in a theology and science course I was teaching. At one point Deb said to the class that we must remember that the light that streams to us from stars and galaxies and nebulae is not just generic light—these streams of light tell a story. They represent cosmic history. All of that light is the collective memory of the cosmos. It tells us about when stars were born. It tells us about when stars matured. It tells us about when stars died (and the stages they went through en route to their deaths). Light tells a story. It tells the story of the universe.

As a preacher, I have spent years training myself to think analogically. Those of us who preach for a living (and those of us who teach for a living) know that one of our main tasks is to take complicated doctrines, theories, or concepts and try to make them plainer and easier to understand by way of analogy. We are constantly saying, “Think of this idea this way . . . “ or “I know this portion of theology sounds difficult to grasp but what if you realize that it is actually a little like this . . .”

Deb’s helpful comment that beams of light tell the universe’s story finally helped me come up with the analogy that made me hit on the “something” that was wrong with this whole scheme. Ever since then, here is what I have told people in order to convey to them what I believe is wrong with the appearance of age argument.

Saying the universe was created in motion is sort of like this: imagine you are like me, a guy who will turn 47 years of age in March of 2011. As a 47-year-old person, I have almost five decades of memories. I can remember my brother being born when I was four years old. I can remember my mother walking me to kindergarten, my family moving to a new area when I was half-way through second grade, graduating from high school, traveling to Europe for the first time, meeting my wife, and the births of my two children. This memory stream, this history of my life that appears to me in my mind, is clear and vivid and undeniable. There is nothing inside of me or in the ways I retrieve these images to tell me they are anything other than iron-clad truth. This is what has happened to me along the way. This is my story. I’ve even got pictures and videos of all those times. I have other people who were there then, too, and who confirm my memories by sharing their own.

So how would I feel if someone—based on some piece of insight they thought they had allegedly received from the Bible or some other source—told me that in reality Scott Hoezee (and everything else for that matter) had been created in motion starting at my 45th year of life in 2009? Yes, everything about me—every DNA test available, every bone scan or memory scan or any other way by which the medical establishment could determine a person’s chronological age—all of it could confirm my 47 years but . . . my actual life would be but 2 years. So what about all those memories that stream to me from 42 years ago when I started kindergarten or from 19 years ago when my first child was born? What about the pictures, the videos, the others who remember it all, too? Well, they look and sound true but strictly speaking are not. None of those things happened (not in the way the last two years’ worth of stuff happened anyway). Installing those memories (of things that never truly took place) were necessary to make Scott’s appearance of age appear authentic but all of them (all 45 years’ worth of stuff) popped into existence at the same moment Scott did a scant two years ago. The events of the last two years are as real as they appear to me. The stuff from the previous 45 years . . . not so much.

If someone told me that it was God who did this all, I would conclude that God is cruel. That sense of cruelty would only be reinforced in case it were also true that within the human sphere of things, there would be absolutely no way I could know about the falsity of all those memories because in the proper exercise of my mental faculties and in the proper use of medical technologies by which my age could be verified, there would be no earthly reason to doubt the veracity of those memories or of the full 47 years they represent.

I would feel deceived.

The history of the universe—when stars were born, when they died, and other events that come to us in the streams of light that beam toward our planet every day—may seem far less personal than the birth of my first child or my remembering when Mom took me to kindergarten. But if all that cosmic information and history are not true—and if there is no way within the normal exercise of our human abilities to measure things to know any better—then why would God build up a story of the universe’s past life in case none of it (save for the last 10,000 years) ever actually took place but was made only to look as though it took place?

I would not like God to do that to me and the story of my life as I apprehend it. But I don’t like this concept any better when it applies to life beyond myself, either. That just doesn’t sound right.

And it isn’t.

Series: The Biblical Premise of Uniformitarianism

Stephen O. Moshier, Gregory Bennett — Sat, 19 Jun 10 07:59:04 -0700

Students of geology learn in their first semester that uniformitarianism is the guiding principle by which geologists interpret Earth’s history. The premise, as formulated by James Hutton in the late 18th century and argued persuasively by Charles Lyell in the middle 19th century, is that geological processes we observe today can be used to explain ancient geological materials and structures. For example, today we see the rock basalt forming by volcanic activity. Since we find basalt layers exposed in Shenandoah National Park, we presume that lavas oozed onto an ancient seafloor sometime in the distant past before the Blue Ridge Mountains formed.

Young-Earth Creationists/Flood Geologists reject the geological principle of uniformitarian on the grounds that (1) it is inherently unbiblical, (2) it was developed to refute biblical catastrophism, and (3) it does not fulfill its promise to help us correctly interpret Earth’s history. These concerns are repeated in Young-Earth creationist literature and even from the pulpits of many churches. Recently in his internet blog, distinguished American pastor John MacArthur (well known for his popular radio ministry) portrayed geological uniformitarianism as a dangerous dogma (here and here).

I respect Dr. MacArthur’s commitment to the authority of Scripture and his passion for the gospel message, but as a professional geologist and Christ-follower I found so many errors in his analysis that I feel they must be exposed in a similar forum. In a recent BioLogos Forum blog, Karl Giberson lamented the all-to-common situation in which “uninformed lay people presume to challenge the scientific community.” Pastors should not be expected to know all the nuances of a concept like geological uniformitarianism, nor the details of landforms and strata in some state park in Georgia (we will get to that). However, pastors should be cautious and responsible if they challenge the consensus of an established scientific discipline in the name of advancing the gospel.

Faulty assumptions, old definitions

Dr. MacArthur defined uniformitarianism as “the theory that natural and geological phenomena are for the most part the results of forces that have operated continuously, with uniformity, and without interruption, over billions and billions of years,” and that the “forces at work in nature are essentially fixed and constant.” There are elements of this description in nearly every textbook or dictionary definition of the term. I like the definition in the Glossary of Geology by Bates and Jackson: “The fundamental principle or doctrine that geologic processes and natural laws now operating to modify the earth’s crust have acted in the same regular manner and with essentially the same intensity throughout geologic time, and that past geologic events can be explained by phenomena and forces observable today....the doctrine does not imply that all change is at a uniform rate, and does not exclude minor local catastrophes.”

The example Dr. MacArthur gives to illustrate this principle is not how geologists apply it in their interpretations of Earth history. He writes, “The uniformitarian sees sedimentary rock strata...and assumes that the sediments that formed them resulted from the natural, slow settling of particles in water over several million years.” Geologists can point to very few natural environments of deposition where this kind of slow settling of particles actually occurs – the deep sea and large lakes come to mind. There certainly are some ancient rocks with textural properties that compare with deep sea and lake deposits. But, many more ancient strata compare perfectly with deposits of modern rivers, deltas, reefs and tidal flats (to name a few among many examples) that form by episodic accumulation of sediments in short periods of time (from seconds to centuries), separated by longer periods of non-deposition or erosion (from months to millennia and even longer).

Paradigm shift: uniformitarianism includes catastrophes

Dr. MacArthur mentions that fossils have a better chance of being preserved if they are buried suddenly (if not catastrophically), and uniformitarian geologists would agree! That’s because modern geologists don’t even subscribe to 19th century uniformitarianism. A paradigm shift occurred in the middle 20th century replacing uniformitarianism with actualism, an addendum to the principle allowing that extreme natural forces have acted in Earth’s history. For our purposes, we will use the term uniformitarianism as it is used by geologists today, not the 19th century definition. Uniformitarianism includes catastrophic events such as thousands of earthquakes from plate tectonics and various meteorite impacts (see footnote ii). As with all science, our understanding of processes has changed from the 19th century to the 21st century.

One of the turning points involved a unique landform called the channeled scablands in eastern Washington State that seemed to defy conventional explanations. Geologist J. Harlan Bretz proposed that they were formed by catastrophic floods of swift, deep water escaping from glacial lakes at the end of the last ice age.¹ The geological community eventually accepted his ideas, but it took over 30 years and some mind stretching to think about such forces as being normal or natural. Bretz was not motivated by biblical flood geology, but by following the evidence where it led him.²

An old earth is not unbiblical

Dr. MacArthur claims that geologists have to keep increasing the age of the earth to make time for all the catastrophes evident in the rock record. That comment ignores the historical development of the geologic time scale as eventually quantified by the middle of the twentieth century. Geologists have known that the earth is in the range of 4.5 billion years old since the 1950s.

Our understanding of Earth history was advanced by thousands of geologists since Hutton and Lyell laboring over the details the earth’s crust and considering each stratum in the context of the planet as a whole. They abandoned the ideas of a very recent creation and global deluge of geological significance because those ideas were not supported by the geological data.

Many of the early geologists knew the implications of the emerging picture for the biblical accounts of origins and they looked to Bible scholars of their time for help. Modern evangelicals know those Bible scholars who accepted the new geology and showed that it was not inconsistent with the meaning of Scripture. Men like B. B. Warfield, James Orr and George Fredrick Wright; men who also contributed to the origins of the fundamentalist movement. Just as respected evangelical biblical scholars of our generation find an ancient creation no threat to biblical faith, such as Alister McGrath, C. John Collins, Bruce Waltke, Wayne Grudem, John Walton and Walter Kaiser.

Dr. MacArthur’s blogs conclude with the geological example of Providence Canyons in southwest Georgia to show the ineptness of uniformitarianism. Poor farming practices in the last century in this upland plateau resulted in severe erosion of the natural drainage system, cutting numerous gullies up to 130 feet deep. If Georgia’s Little Grand Canyon could form in only decades, why couldn’t receding water from Noah’s flood carve Arizona’s Big Grand Canyon? That both canyons were carved by water is about the extent of the comparison! A detailed look at the strata eroded in Providence Canyons provides further evidence that actualistic assumptions work.³

Uniformitarianism reflects God’s unchanging nature

Finally, do we really want to condemn uniformitarianism, or its offspring actualism, as an unbiblical premise? Dr. MacArthur quotes scriptures that ring of the catastrophist actions of God in nature. However, there are also scriptures that speak of the unchanging nature of God and...well, nature. Ecclesiastes 1 comes to mind with its poetic refrains: “Generations come and generations go, but the earth remains forever....All streams flow into the sea, yet the sea is never full. To the place the streams come from, there they return again.....What has been will be again, what has been done will be done again; there is nothing new under the sun. Is there anything of which one can say, "Look! This is something new"? It was here already, long ago; it was here before our time. There is no remembrance of men of old, and even those who are yet to come will not be remembered by those who follow.”

In Part 2 and Part 3, Gregory Bennett will explore how the concept of uniformitarianism as used by geologists is necessary for our full understanding of God’s relationship to nature. He will also explore how uniformitarian principles are used by every biblical interpreter including use within one of the core tenants of Christian doctrine, God’s providence.

Notes

1. This event occurred about 11,500 years ago during a period of rapid global warming over a 200 to 400 year period of time, according to evidence from ice cores in Greenland and lake and cave sediments across the Northern Hemisphere.
2. In addition, geologists find evidence of major catastrophic events such as meteorite impacts. One example is the Chicxulub crater buried below the surface on the Yucutan Peninsula of Mexico, resulting from a meteorite impact about 65 million years ago and approximately coinciding with the dinosaur extinction. It was discovered during seismic exploration for oil. The crater is over 100 miles in diameter, and left telltale ash about 1,000 miles away in the sediments offshore Florida, and over 6,000 miles away in Italy and Denmark.
3. Once the protection of surface vegetation was removed, streams easily cut through the poorly consolidated sand deposits of the Upper Cretaceous Providence Formation to create the numerous large gullies at Providence Canyons. Those sand deposits compare with sands that are deposited today in near-shore marine conditions (like off the coast of Georgia today). The deposits feature cross-bedded layers formed by migrating sand bars with burrow tubes and traces from animals that lived on and below the sea floor (Donovan and Reinhardt, 1986). This is no flood deposit where animals were suddenly buried in a catastrophic event, but a record of episodic sedimentation in an ancient sea where marine critters ate, reproduced and died under normal marine conditions; modern uniformitarianism exemplified!

Evidences for Evolution, Part 1: An Ancient Earth

David Kerk, Falk, Darrel — Mon, 31 May 10 08:00:43 -0700

A literalistic view of Genesis causes many evangelicals to believe that the earth is less than ten thousand years old. Christian children and young people frequently grow up being told that the earth is young and that evolution is a lie. The most popular science/religion web-site by far according to Alexa ratings is “Answers in Genesis”, and its museum, dedicated to a young earth perspective has attracted over 1 million visitors since its opening two years ago. Since evangelicals, we believe, are correct about so many other all-important issues, how can we be so certain that so many are so wrong about this one? Consider sending this link to a young earth friend or pastor. Some think that the science behind this matter can’t be trusted. Nothing could be further than the truth.

The beauty of the scientific process is its inherent scepticism. (See "What Scientists Do" by Steven Benner). If there is only one way of reaching a conclusion, the scientific process requires the scientist to remain highly sceptical. The only conclusions in science which are widely accepted are those which are supported by multiple, reinforcing lines of evidence – “all roads must lead to Rome”. If there is even one scientific trajectory that seems to clearly lead off to Peoria instead of Rome (to use a recent analogy of Francisco Ayala), the scientific process demands that the scientist find out why. The scientist who does not retain an attitude of scepticism when there is only a single line of evidence, and particularly one who ignores other, conflicting lines of evidence, is on a stubborn trajectory of his own—a trajectory to failure. If the only reason for following the directions which “lead away from Rome” is a particular view of Scripture, then it is important to consider the possibility of human error. Biblical hermeneutics, after all, is a human enterprise just as science itself is. For example, John MacArthur in his current series on Genesis is human and is interpreting Genesis in his way just like the rest of us. He, wonderful pastor and shepherd that he is, interprets Scripture too. There is good reason to be quite certain that the interpretation he subscribes to is mistaken.

As Christians, we are called to follow Jesus. In so doing, Jesus said we are to love the Lord our God with all our heart, soul and mind—not just our heart and soul. Indeed if we close our mind, we are actually disobeying what Jesus said was the greatest commandment of all. So let’s not be shy about using those minds. Are there multiple independent ways of keeping track of time since the creation of the earth? If so, do each of those ways point to the same conclusion?

The best known method of calculating the age of material on earth depends on the well-established fact that certain elements in the earth’s crust are unstable and decay at a fixed rate that can be measured. (For an introduction to this topic see this BioLogos FAQ.) This instability functions sort of like a set of clocks that have been ticking through the eons of time. Indeed there are many types of unstable elements; there are many ticking clocks. Each of the various clocks tick at a different rate. The rate of each can be calibrated, and, with an amazing degree of consistency, all “clocks” point back to the same starting point: an ancient earth with rocks that are hundreds of millions and even billions of years old. This “ticking clock” technique is known as radiometric dating.^1,2

There are other totally independent ways of estimating the age of material on earth. To appreciate how these work, perhaps we should start with shorter spans of time, which for human beings are much more readily comprehensible. Some of the fondest boyhood memories of one of us (DK) come from visits to the majestic California redwood forests. He especially remembers an exhibit of a section from a giant tree which showed the pattern of growth rings within it. It turns out that these rings accumulate in response to seasonal differences in rainfall and temperature, which in turn produces differences in growth rate. Fastened within this huge slab of wood was a series of tags, proceeding from the surface inward, demonstrating the dates of major historical events: the landing of the Pilgrims on Plymouth Rock; Columbus’ discovery of the New World; the Norman conquest of England, and so forth. It was possible to see in the yearly growth rings a history of what seemed then to be the very distant past!³

Growth layering processes are not restricted to trees. Many species of marine invertebrates accumulate calcium carbonate from their watery environment and incorporate it into some form of shell. Examples would be clams and corals. In fact, for these species, the variation in shell deposition occurs on a both a daily and a yearly basis, so an even finer counting of time periods is possible.⁴

Just as it is possible to count the rings in trees and correlate their age to known historical events in the past, it is also possible to count the banding patterns preserved in the fossils of marine organisms, and use this as a method to estimate their ages. Let’s see how it works.

Astronomical data, developed and analyzed over the past couple of centuries, has revealed that the rotation of the earth is gradually slowing down. This is due to the friction created daily by the moving tides on the earth’s surface, produced by the gravitational pull of the moon and sun. Furthermore, as the earth slows down slightly, some rotational energy is transferred to the moon, which alters its orbit slightly (its orbit is moving slowly away from the earth). The data leading to these conclusions range from analysis of ancient solar eclipses (whose dating allows the precise position of the earth, sun and moon to be determined) to bouncing laser beams off mirrors placed on the surface of the moon by the Apollo astronauts. For our purposes, what will be important is the slowing of the earth’s rotation. This predicts that the length of each day has been slowly increasing since the formation of the earth/moon system. The average increase in the day length is estimated at 2.3 milliseconds (.0023 seconds) per century.^5,6 Hence as we examine events in the past, day length was shorter, by an amount that can be calculated. Ten thousand years ago, a day would have been .23 seconds shorter than it is today. If direct experimental estimates of day length can be obtained, they allow an estimate of the age of the material.

One way that such experimental estimates of day length can be obtained is through the periodic growth rings deposited in the shells of marine invertebrate organisms. Take for example a clam living in an intertidal environment. If the tide is in and the shell is open, it can readily absorb oxygen from water, use aerobic metabolism, and incorporate calcium carbonate into its shells. When the tide is out and the shells are closed, however, little oxygen can be absorbed, anaerobic metabolism is used, shell decalcification occurs, and organic rich material accumulates in the shell. This alternating pattern of shell deposition occurs on a daily basis, and is clearly visible in both shells from living and fossil clam species by microscopic examination. Furthermore, shells contain an identifiable mark resulting from the first freezing day of winter, and from the first really hot day of summer. Hence a yearly growth interval can be readily determined.⁷

When such data are analyzed for a number of fossil species, it is clear that the number of days these organisms experienced each year was higher than today. Given that, we have another clock - a totally independent way of measuring the age of certain fossils. So how well do clocks based upon radiometric dating agree with those based on measuring rings in certain sea shells?

As already mentioned, organisms living 10,000 years ago would have experienced shorter days, but they would only have been shorter by 0.2 seconds. Organisms living 1 million years ago would have experienced a day length that was 20 seconds shorter. If the earth really is very, very old, organisms living 465 million years ago, for example, would have experienced approximately 416 days per year, each day being about 21 hours long.⁷ Amazingly, shelled fossils in formations dated by radiometric clocks to be about 465 million years old show, by their banding patterns, that the days really were three hours shorter. In fact the two sets of clocks agree within 1 percent!

Another way such estimates of ancient day length can be derived is to look at the periodic patterns formed in fine silts in ancient river estuaries. The daily tides produce shifts in the mud, leaving a fine layering pattern, which is recorded in rock as these sediments transform into materials such as sandstone (such deposits are called “rhythmites”). Other shifts in the mud are produced over longer time intervals, including seasonal and yearly shifts. By counting the number of daily depositional layers per year, in a similar fashion to work with marine organism shells cited above, an estimate of ancient day length can be derived. One advantage of the rhythmite analysis method is that it can be applied to more ancient materials, in eras of the earth’s history when organisms suitable for shell analysis were scarce or non-existent. For example, radiometric analysis of certain rock formations in South Australia dated them at 620 million years of age. On this basis one would predict that the day/night cycles should have been about 20 hours long in these formations. Actual measurements of day length from the preserved mud banding patterns, although off from the expected by ten percent (estimated day length is 22 hours) is again consistent with the formation being hundreds of millions of years old just as the radiometric dating has predicted.⁸

In conclusion, there is data derived from three independent sources: the decay of radioisotopes, the growth patterns recorded in fossilized shells of marine organisms, and rocks containing tidal depositional material from river estuaries, which all agree on an ancient age for the earth. Furthermore, by a totally independent method it is also possible to measure the age of the universe as a whole and again it is billions, not thousands of years.

All of the roads in God’s book of Nature “lead to Rome” (i.e an ancient earth) - it is only mistaken human interpretation of Scripture that causes some of our precious brothers and sisters in Christ to end up in Peoria.

The Second Creation Story and "Atrahasis"

Pete Enns — Tue, 25 May 10 09:00:34 -0700

Last week we looked at Genesis 1 and Enuma Elish. Another very important discovery in Ashurbanipal’s library is the story commonly referred to as the Atrahasis Epic. Though in the nineteenth century only fragments of the story were found, a more complete version was found in 1965, dated to the seventeenth century B.C.

Atrahasis is the name of the Noah-like figure in this story and it means “exceedingly wise.” The Atrahasis Epic and another ancient story called the Gilgamesh Epic overlap a lot with the biblical flood story. We will get to that issue in a future post. Atrahasis, however, is more than just a flood story. It is a story of the origins of the gods (theogony) and of the cosmos (cosmogony).

Atrahasis is important to biblical scholars because of it similarity to Genesis 2-9. Both stories share a similar storyline: creation, population growth and rebellion, flood. They also share some important details within that storyline.

The degree of overlap between the stories suggests to some scholars that Genesis 2-9 may be an Israelite version of Atrahasis, although it is best not to be dogmatic about that. It is very clear, however, that there is a lot of conceptual overlap between them.

The best way to show the similarities between these stories is in a chart. The one below is from Daniel Harlow, which is adapted from a chart by Bernard F. Batto¹. I have made slight adjustments for clarity.

It goes without saying that there are clear differences between the stories (which we will see in more detail when we get to the flood story). But, just as we saw last week with Genesis 1 and Enuma Elish, (1) the differences only stand out because of the similarities, (2) the differences do not justify minimizing the similarities.

As we saw with Genesis 1 and Enuma Elish, Genesis 2-9 and Atrahasis breathe the same air. They share ancient Mesopotamian ways of talking about origins. This is a clear indication that the second creation story does not speak to contemporary science. Hence, (1) it cannot and should not be harmonized with contemporary science, (2) it should not control what can be concluded from scientific investigation.

Genesis 2-9 is an ancient story asking addressing ancient issues. Understanding that ancient context will keep us from asking this story to deliver more than it is prepared to. And it will also help us mine the theological depths of what this story said to ancient Israelites nearly three millennia ago.

Israel’s two creation stories are clearly distinct, which makes one ask why there are two to begin with and why they are placed side-by-side as they are. Unfortunately, Genesis does not come with an introduction explaining why the author did what he did.

The conventional scholarly explanation is a bit involved, but here is the main outline. The second creation story in Genesis is actually Israel’s older creation story, written perhaps sometime during the early period of the monarchy and fully engaged with common Mesopotamian traditions. The first creation story in Genesis was written second, after the return from Exile (539 B.C.), and was influenced by Israel’s long experience in Babylon captivity.

Genesis 1 highlights God’s complete control over creation, employing and transforming familiar Mesopotamian themes such as the cosmic battle motif. That story was placed at the beginning of Israel’s Scripture. The older creation story was edited to reflect its new position as subordinate to Genesis 1.

As I have suggested in previous posts, one way of looking at it is this: What had been Israel’s original story of creation (the Adam story) was transformed to a story of Israel’s creation.

As I stressed earlier, such a suggestion is not meant to cut off discussion but promote it. The meaning of Israel’s creation accounts has been pondered since before the time of Christ, and no one should think that conversation has come to an end in an internet post or two.

Whatever one concludes about Israel’s creation stories, the extra-biblical stories should not be kept at arm’s length from Genesis. They are clearly very important for understanding the nature of Genesis and what it means to understand it properly today.

Series: The Flood: Not Global, Barely Local, Mostly Theological

Paul Seely — Fri, 05 Feb 10 08:00:05 -0800

Part Two: Noah’s Flood was Barely Local

There are so many close similarities between the biblical Flood account and the Mesopotamian accounts that conservative scholars like Alexander Heidel, Merril Unger, Donald Wiseman, John Walton and others have concluded that the biblical and Mesopotamian flood accounts go back to a common tradition about the same flood.¹ This means if we can locate the flood mentioned in the Mesopotamian accounts, we will have located the biblical flood.

Working from inscriptions and the Sumerian King List, the Sumerian Noah, Ziusudra, who lived in the city of Shuruppak, can be roughly dated to c. 2850 B.C. This agrees quite closely with the date of the only Mesopotamian flood that left simultaneous deposits in three locations (Shuruppak, Uruk, and Kish). A number of ancient Near Eastern scholars have, therefore, concluded that this flood is probably the one mentioned in the Mesopotamian and biblical accounts.²

Historian Jack Finegan writes,

Since in Sumerian tradition Shuruppak was the last ruling city before the flood and Kish was the first thereafter, it was presumably the inundation attested at Shuruppak between the Jemdet Nasr and Early Dynastic periods (and at Uruk and Kish at about the same time) that was the historic flood so long remembered. The date was about 2900.³

It is plausible that the Mesopotamian flood of c. 2900 B.C. was the historical basis of the biblical account. A Mesopotamian flood theory is the only flood theory that explains the fact that no other flood stories are anywhere near as close to the biblical account as the Mesopotamian accounts.⁴ It is also the only flood theory that agrees with the biblical description of the sources of the Flood’s water as all being fresh water sources.⁵

So, there is an objective basis for an actual biblical Flood. Why then do I title this post “Barely Local?” The answer is that neither the flood of 2900 B.C. nor any other actual local flood, such as the Black Sea flood, nor the melting of ice caps at various historical points closely fits the biblical description. Local flood theories do not fit the biblical account with regard to secondary issues such as lasting one year and destroying all the birds (even in a local area). More importantly, no local flood theory agrees with the biblical account at the most critical points: landing the ark in the Ararat mountains, covering the entire Near East (Genesis 9:19, “all the earth” = Genesis 10), establishing Noah as a new Adam, i.e., as a new beginning of the human race⁶, and dismantling the universe by reversing creation days two and three.⁷

We can say then that the biblical account may well be based upon an actual Mesopotamian flood and therefore is not properly designated a myth. At the same time, it is evident from geology, anthropology and archaeology that the above mentioned four critical points in the biblical description, which go well beyond the scope of a local flood, cannot be regarded as actual, factual history. The biblical account would, therefore, be properly described as Legend (or better, Parabolic Legend, as I will describe in my third post).

A fact often missing from the discussion of whether the Flood is global or local is the fact that Genesis 1-11 is accommodated to the limited scientific knowledge of the Israelites. We see this in the Flood account’s definition of “the whole earth.” Genesis 9:19, “These three were the sons of Noah: and of these was the whole earth overspread,” leads us to the author’s definition of “the whole earth.” It is the area overspread by the descendants of the three sons of Noah. Contextually, this area is set forth in Genesis 10. The “whole earth” according to the (final) author of Genesis 6-10 is thus the greater Near East.

This contextual definition of “the whole earth” excludes the usual ideas of a limited local flood as well as the idea that the Flood is described in Scripture as covering our modern globe. The biblical account is not written from the perspective of God’s knowledge of geography but is accommodated to the Israelites’ limited knowledge, wherein “the whole earth” both extends to and is limited to the greater Near East.

In addition, the sources of the Flood’s waters in Scripture depend upon an ocean above the sky and beneath the earth. The account is thus divinely accommodated to the ancient Israelites’ view of the universe.⁸ Since it involves ancient Near Eastern “science,” which has since been superseded, the biblical description is not all actual-factual. The biblical account is, in fact, much grander than the actual event, a point that we will look at in my third and final post.

Understanding Earth

Fri, 25 Sep 09 17:00:30 -0700

Every Friday, "Science and the Sacred" features an essay from a guest voice in the science and religion dialogue. This week's guest entry was written by Karen Strand Winslow, Ph.D., a Professor of Biblical Studies at the Graduate School of Theology, Azusa Pacific University.

When we read Genesis 1.1: "in the beginning God created the heavens and earth" we picture the origin of the atmosphere, space, solar systems, and galaxies. We think of the creation of the planet in our solar system named "Earth," whose shape is an oblate spheroid or a rotationally symmetric ellipsoid. This mental picture is natural, because the English term "Earth" is the name of the planet in this solar system on which humans reside. But in Genesis 1 "earth" does not mean the planet Earth. Genesis reports the origin of the "heavens and earth" as such terms meant in the author's time and within his worldview, which did not include a twenty-first century acquaintance with astronomy. What does "earth" mean in Genesis 1? The answer is provided in the text itself.

Genesis 1.1 "In the beginning God created ha-shamayim and ha-aretz [earth]." Genesis 1.1 is a title for what is to follow. Genesis 1.2a "The earth [ha-aretz] was without form and void" (there was no earth yet). After God created light, named day and night, and made a firmament (the heavens or sky) to divide the waters, God made ha-aretz.

Genesis 1.9 "And God said, 'Let the waters under the sky [ha-shamayim] be gathered together into one place, and let the dry land [ha-yabbashah] appear.' And it was so. 10 God called the dry land eretz [English: "earth"] and the waters that were gathered together he called seas. . . . "

Ha-aretz is "dry land" [Hebrew: ha-yabbashah]. God created land from which seed bearing plants and fruit trees would emerge and on which the creepers would creep. To the biblical writer, this land was not a planet or a globe spinning on its axis or orbiting the sun along with other planets.

Genesis 1 explains the origins of the land on which people live, farm, and travel. Ha-aretz is often a synonym for ha-adamah, "ground" in the Bible. Throughout the rest of Genesis, the biblical writers use ha-aretz to describe one's homeland, property, farmland, other regions, and bowing to the ground. Eretz is translated by the English term "earth" 660 times, and usually it refers to ground, soil, or the place where one is standing. In these cases, eretz is a synonym for the Hebrew adamah, the stuff from which adam is made in Genesis 2.7. The same term is translated by the English "land" or "country" 1,620 times in the Revised Standard Version, meaning location or place, boundaried or unboundaried, as in countryside. In addition, ha-aretz can mean the realm of all creatures, the realm or habitation of the living (Job 28.13; Psalm 27.13). Nowhere in the Bible does "earth" refer to a planet. Why is this important for science and theology?

Ha-aretz translated properly as "land," takes the air out of controversies over whether the Genesis flood story depicts a local or "universal" flood, an aspect of the polemic of young earth theorists and "creationists." (They suppose the earth to be less than 10,000 years old, based on adding the genealogies of Genesis. This is mixing genres--categories of literature--to develop a Western and even mathematical role for the Bible, while genealogies appear to link Abraham to Noah and Noah to Seth).

The term "universal flood" usually means that flood waters covered the entire planet. According to young earth theorists, the one-year Genesis flood laid down millions of layers of sediment across the planet, causing the earth to appear to be millions of years old. The basis of the young earth claim is the phrase "kol ha-aretz" in Genesis 7.3 and 8.9 and translated as "the whole earth." For readers who have a planet in mind, this translation biases them to believe the text claims Noah was saved from a global flood.

But the flood story of Genesis 6-9 assumes the same worldview represented in Genesis 1 and uses the same vocabulary throughout, including ha-aretz to mean land or dry ground. Throughout the flood account in Genesis, eretz and adamah are used synonymously. "Kol ha-aretz" means all the land known to the originators of the flood story, perhaps a location around the Black or Mediterranean Seas, which would have been the "world" of the biblical writers. Although flood stories exist among some ancient cultures and evidence for flooding is apparent in some areas around the world, some regions have no stories or traces of flooding. The layers of sediment and fossils in North America alone demonstrate without question that a single flood could not have deposited them. The ancient texts and artifacts of Ugarit, Egypt, and Japan contain no flood narratives, and there are only a few from Africa. Thus, the closest neighbors of Israel do not "remember" flooding.

Neither is there geological data to support a global flood around ten thousand years ago. Eight times more water than is now on earth would have been required for waters to cover the planet. There would have been the need for a new creation to restore the earth after the flood, because salt water destroys vegetation. Certain geological phenomena would have been destroyed if there had been a global flood. In Auvergne, France, there are cones of scoria and ashes from long extinct volcanoes, but there are no signs of effects of water. In addition, the 35,000 year old cave drawings from the Dordogne area of France (and countless other extant artifacts) would have been destroyed by a global flood.

The Bible was not intended as a primitive science manual that presented rudimentary scientific facts that would be verifiable at a later date when science caught up. When the biblical writers refer to "all the land" or even "the whole world," they refer to their whole world, not ours; they were not thinking of a planet, because they did not know they were living on a planet.

By observing the known world in all its magnificence--noticing, distinguishing, and naming its grandest features--Genesis 1, Psalm 104, Job 38 and Isaiah exemplify fundamentals of science--observation and organizing, but they are primarily theological. They cause us to worship God, as creator of all that is.

How are the ages of the Earth and universe calculated?

Introduction

Age of the Earth from seasonal rings and layers

How can an old Earth be reconciled with Genesis? See Scripture Interpretation

Age of the Earth and solar system from radiometric dating

Age of galaxies from the travel time of light

What about the ages of stars and galaxies, and the age of the whole universe? One way to measure these ages is with the travel time of light. Light travels incredibly fast – 300,000 kilometers per second, or 186,000 miles per second. On Earth, the delay due to light travel time is a tiny fraction of a second. But in space, the distances are so vast that the light takes a substantial amount of time to travel to us: 8.3 minutes from the Sun, 4.3 years from the nearest star, and about 8500 years from the center of the Milky Way galaxy. That delay means that we don’t see these objects as they are right now, but as they were when the light left. The universe actually works as a sort of “time machine,” in which we can see into the past simply by looking far away.

The calculation of the light travel time is simple once you know the speed of light and have a measurement of the distance. The speed of light is well known from experiments on Earth, and various astronomical observations confirm that the speed of light has not changed over the history of the universe. But measuring distances in astronomy is not trivial – you can’t just string a measuring tape from here to the center of the galaxy! Instead, astronomers use several interlocking methods to determine the distances, such as geometric calculations and brightness measurements. For example, some galaxies look much smaller and fainter than other galaxies of the same kind, showing they are much further away.⁸

The Andromeda galaxy, a near neighbor to our own Milky Way galaxy, is 2.3 million light years away. That is, we are seeing it as it was 2.3 million years ago. But that is just our local neighborhood. In recent decades, astronomers have detected galaxies located several billion light years away. If the light has been traveling billions of years to reach us, then the universe must be at least that old. This is completely independent of radiometric dating of the solar system, but both methods point to an age of billions of years, not thousands.

See Did God create everything recently but make it appear old?

Age of the universe from expansion

Not only can astronomers measure the distance of galaxies, they can measure how galaxies are moving. Galaxies are not holding still in space, nor are they moving randomly. Some galaxies are moving towards their neighbors, attracted by their mutual gravity. But the biggest pattern we see is that galaxies are moving apart from one another. This motion apart is not all at the same speed; instead it follows a pattern where galaxies that are further apart are moving more quickly.

This particular pattern indicates the whole universe is expanding. To see why, consider a loaf of raisin bread. The raisins are like galaxies and the dough is like the fabric of space in the universe. As the dough rises, it carries the raisins along, pulling them apart from each other. Raisins that started out on opposite sides of the loaf will be a few inches farther apart after the dough rises, while raisins that started out near each other may only move half an inch. So, the speed of their motion is proportional to the separation between them. In the same way, the space of the universe pulls galaxies further apart as the universe expands.

Astronomers detect a galaxy’s motion by looking at its light spectrum. When a galaxy is carried away by the expansion of space, its light waves are stretched out, making it appear redder. The change in the galaxy’s color is called the red shift, and can be used to calculate its velocity. From the measurements of many galaxies, astronomers can accurately measure the expansion rate of the universe as a whole.

The age of universe can be determined by imaging what the universe looked like in the past, “rewinding” the expansion. In the past the galaxies must have been closer together, and in the distant past they would have been packed together in a tiny point. If we assume that the expansion rate is constant over time, the age for the universe as a whole is about 10 billion years. However, astronomers have been working over the last 20 years to determine how the expansion rate changes with time. We now know that early in the universe the expansion was slowing down, but now it is speeding up. Using careful measurements of this change in expansion rate, the age of the universe is now known quite precisely to be 13.7±0.13 billion years. ⁹

Conclusion

Many different and complementary scientific measurements have established with near certainty that the universe and the Earth are billions of years old. Layers in glaciers show a history much longer than 10,000 years, and radiometric dating places the formation of the Earth at 4.5 billion years. Light from galaxies is reaching us billions of years after it left, and the expansion rate of the universe dates its age to 13.7 billion years. These are just a sampling of the types of evidence for the great age of the Earth and the universe; see the resources below for more.

How should we interpret the Genesis flood account?

Tue, 14 Apr 09 18:21:20 -0700

"I will send rain on the earth forty days and forty nights; and I will blot out from the face of the land every living thing that I have made." — Genesis 7:4

Introduction

The Genesis Flood of Genesis 6-9 tells a fascinating story. Sometimes referred to as Noah and the Ark, it is a common fundamentalist claim that the biblical flood must have been a worldwide one, or else Scripture as a whole is undermined. From this point of view, the flood is often used in an attempt to account for the geologic column, which is otherwise seen as evidence of a very old Earth. However, a balanced interpretation of Scripture does not force the reader to believe that the Flood was a worldwide phenomenon. The scientific and historical evidence summarized below supports the idea that the flood was indeed catastrophic, but that it was local, recent and limited in scope. Beyond its place in history, the Genesis Flood is also a part of the greater narrative of the Bible. It highlights theological points concerning human depravity, faith, obedience, divine judgment, grace and mercy.¹

The History of “Flood Geology”

In the 19th century, a growing body of extrabiblical evidence began to undermine the traditional belief in a global flood. As early as the first half of the 19th century, geologists and theologians Edward Hitchcock, Hugh Miller and the Rev. John Pye Smith viewed this evidence not as a threat to faith, but as an occasion to reach a better understanding of Genesis.²

But in the 20th century, George McCready Price, a Seventh-day Adventist from Canada and self-taught amateur geologist, took a less compliant stance and began the modern flood geology movement, which ascribes many features of Earth’s present state to a recent, global flood. In his book The New Geology, published in 1923, Price explained the Christian fundamentalist perspective of geology, and he did so with such style and sophistication “that readers untrained in geology are generally unable to detect the flaws.”³ Others followed Price in the modern flood geology movement, including Byron Nelson, Harold Clark, Alfred M. Rehwinkel, John C. Whitcomb, and Henry M. Morris.

See "What was the Christian response to Darwin?".

In the 1950s, Bernard Ramm, a baptist theologian and author of The Christian View of Science and Scripture, along with J. Laurence Kulp, a geologist and Plymouth Brethren member, critiqued Price’s book by pointing out critical errors and omissions.⁴ Ramm, Kulp and others encouraged the American Scientific Affiliation and other organizations not to support flood geology.⁵ In 1961, Young Earth Creationists Henry M. Morris and John C. Whitcomb, Jr. updated Price’s work by writing The Genesis Flood. This book argued that the creation of the Earth was relatively recent, and that the Fall of Man started the second law of thermodynamics. The book also claims that Noah’s Flood was global and produced most of the geological strata we see today. Many regard the work of Morris and Whitcomb to be a major foundational step in the development of modern day creation science, which has since gained a worldwide foothold.

Let us now consider the actual evidence for this position from both the Bible and from science.

A Local Flood

The language used in Genesis 6-9 does not insist that the flood was global.

First of all, the Hebrew kol erets, meaning whole Earth, can also be translated whole land in reference to local, not global, geography. The Old Testament scholar Gleason L. Archer explains that the Hebrew word erets is often translated as Earth in English translations of the Bible, when in reality it is also the word for land, as in the land of Israel.⁶ Archer explains that erets is used many times throughout the Old Testament to mean land and country. Furthermore, the term tebel, which translates to the whole expanse of the Earth, or the Earth as a whole, is not used in Genesis 6:17, nor in subsequent verses in Genesis 7 (7:4, 7:10, 7:17, 7:18, 7:19).⁷ If the intent of this passage was to indicate the entire expanse of the Earth, tebel would have been the more appropriate word choice. Consequently, the Hebrew text is more consistent with a local geography for the flood.

Moreover, in this period of history, people understood the whole Earth as a smaller geographical area. There is no evidence to suggest that people of this time had explored the far reaches of the globe or had any understanding of its scope. For example, the Babylonian Map of the World,⁸ the oldest known world map, depicts the world as two concentric circles containing sites of Assyria, Babylon, Bit Yakin, Urartu, a few other cities and geographic features all surrounded by ocean. There are also small, simple triangles that shoot out from the ocean labeled as nagu or uncharted regions.⁹ Contextual evidence also suggests that Greek geographers developed comparable maps during the middle of the first millennium, where Greece was positioned in the middle of a circle surrounded by oceans.¹⁰ These maps remind us that people were most familiar with the regions surrounding their homelands. Therefore, to say that something happened in the kol erets –– or referring to "all people" (Genesis 6:13), –– would have been an appropriate way of referring to the entirety of Earth and its population in a manner in which ancient Israelites would have been familiar. Davis A. Young, author of The Biblical Flood: A Case Study of the Church's Response to Extrabiblical Evidence, sums this up when he states:

"Given the frequency with which the Bible uses universal language to describe local events of great significance, such as the famine or the plagues in Egypt, is it unreasonable to suppose that the flood account uses hyperbolic language to describe an event that devastated or disrupted Mesopotamian civilization — that is to say, the whole world of the Semites?" ¹¹

Scientific Problems with a Universal Flood

There are a number of practical problems that conflict with the idea of a global flood.

First, a universal flood would have changed the topography of the land. For example, in the event of a worldwide flood, the Hidekkel, or Tigris, and Euphrates rivers of Genesis 2:14 would have disappeared under layers of flood-laid sedimentary rock.¹² Instead, the Euphrates is mentioned again in Genesis 15:18, and the Hidekkel is alluded to in Daniel 10:4. This suggests that the rivers’ integrity was maintained.¹³

Second, it would require an inordinate amount of water to flood the entire Earth. One popular explanation for this problem is that prior to the flood, the world was watered by mist from a global canopy of water vapor which then condensed, causing the first rains to flood the Earth (Genesis 2:5-6). However, this explanation is incongruent with archaeological evidence that concludes ancient Mesopotamia — the land of the Tigris and Euphrates — was “an extremely arid environment that necessitated the use of irrigation for successful agriculture.”¹⁴ Furthermore, the pressure necessary for the condensation of such a large quantity of water would have been fatal for all living creatures. In fact, a closer look at the Septuagint version of the Old Testament shows that the word for fountain was used in place of the word for mist. Some modern translations have used similar words like stream and spring.¹⁵ In either case, the water is said to have risen from the Earth, which makes it more likely that these terms were referring to irrigation canals.¹⁶ A similar terminology is used in reference to the flood (Genesis 7:11), where “fountains of the great deep burst open, and the floodgates of the sky were opened.” But when we look closely at the original Hebrew text and consider the use of the words fountains and deep in other passages, it is more likely that the fountains of the deep were also irrigation canals.¹⁷

Another supposition is that all animals and humans are derived from the survivors on Noah’s Ark. There are several problems with this idea. First of all, there is no way that the 2 million known species of animals could have fit onto the ark — not to mention the estimated 10 to 100 million species yet to be discovered. The dimensions of the Ark were 300 cubits by 50 cubits by 30 cubits (Genesis 6:15). At 18 inches per cubit, the Ark would have been 450 feet long, 75 feet wide and 45 feet tall. This was indeed a large ship by the standards of the time, but not nearly large enough to carry such a vast and varied cargo. Getting all of the animals to fit on the ark, along with the necessary food would not have been feasible. Some have argued that not all species were included, but only representatives of each type. Not only would this still represent an improbably great number of creatures, it would also require that the evolution of related species be drastically accelerated after the flood, in order to account for current diversity of species.

Finally, the migration of animals across mountains and oceans is quite difficult to explain. To make matters worse, there are no traces of animal ancestors along the proposed courses of migration. These are just a few of the many scientific problems with interpreting Genesis 6-9 as a truly universal flood. Efforts to find physical evidence of a global flood have failed. Even some of the most capable Christian researchers, including John Woodward, George Frederick Wright, William Buckland and Joseph Prestwich, all failed in their searches. Young states, “It is clear now that the evidence they were searching for simply does not exist.”¹⁸

The Location of the Flood

Assuming that the Flood was local, its location has not yet been precisely determined. Though excavation of flood deposits in Mesopotamia provides evidence of ancient flooding, there is no evidence that it is unambiguously the biblical flood. ¹⁹ Young writes:

"Nevertheless, the stratigraphy of some of the Mesopotamian flood deposits, literature pertaining to Gilgamesh and ancient Sumerian cities, the New Eastern setting of the biblical account, and the obvious affinities of the biblical and Mesopotamian flood traditions all converge to suggest that there may very well have been a catastrophic deluge in the Tigris and Euphrates River valleys that severely disrupted the civilization of that area — a civilization that represented the world to the biblical writer — and it may be that this is what the biblical story is all about."²⁰

Scholars still speculate about where a great flood may have occurred in the Near East. For example, in the 1990s Columbia University geologists William Ryan and Walter Pitman concluded that a massive local flood took place in the area we now know as the Black Sea. They theorized that when the Ice Age ended and glaciers melted, a wall of seawater surged from the Mediterranean into the Black Sea.²¹ This flood, which may have occurred around 5500 B.C., would fit into the Old Testament timeline of Noah’s Flood. Robert Ballard, famous for finding the Titanic, led a 1999 expedition with the hope of finding more evidence for this theory. The expedition revealed an ancient shoreline for the Black Sea, and after radiocarbon dating, the findings supported their hypothesis that a freshwater lake and surrounding manmade structures were in place before the flood. Conflicts with the Black Sea explanation do exist, however. For example, 5500 B.C. is too early for Noah to have used metal tools to create the ark, and the location of the Black Sea does not fit the Sumerian and Babylonian accounts of the flood, which strongly suggest that it took place in Mesopotamia.

The location of the flood remains mysterious and of continued interest to modern geologists.

Lessons of the Flood

Regardless of the details surrounding the event, there are significant theological lessons to be learned from the Flood narrative.²⁸ In the early church, Tertullian, Jerome, Ambrose, Cyril of Jerusalem, and Augustine understood the story of the flood to encourage moral conduct.²⁹ For example, Noah can also be used as an example of Christian perseverance, since he had great faith to build the Ark that God commanded (see James 5:11). Origen, Jerome, Augustine and others also employed other allegorical methods to illustrate Christian principles. ³⁰ Being conversant with other flood stories from ancient Mesopotamia as well as the general theology of Genesis will also help us understand the point of this story. The biblical flood is a response by God to the corruption of humanity, save Noah. The flood waters are not a random punishment, however, but an undoing of creation –– a return to the state of chaos that existed before God gave order (this is described in Genesis 1). The waters of chaos had been kept at bay by the firmament, the raqia, which is a solid dome above, and by the earth below. That is how Earth became habitable. When we read in Genesis 7:11 that the "fountains of the great deep burst open, and the floodgates of the sky were opened", it means that God is letting the barriers give way so that the waters of chaos can crash back down upon the Earth, thus making it uninhabitable again. In other words, God's intention in this story is to bring Earth back to its state of chaos and start over again, with a new "Adam" (Noah). We will read throughout scripture that God's plan of "starting over" will culminate in Jesus, the "last Adam" (1 Corinthians 15:45).

Conclusion

An informed reading of the Genesis story neither permits nor requires it to be a universal, global flood, and geology does not support a universal reading. A non-global interpretation does not undermine the lessons learned from the Genesis Flood account that are pertinent to the life of faith.
