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. (Updated April 16, 2012)

We at BioLogos believe that God used the process of evolution to create all the life on earth today. While we accept the science of evolution, we emphatically reject evolutionism. Evolutionism is the atheistic worldview that says life developed without God and without purpose. Instead, we agree with Christians who adhere to Intelligent Design and Creationism that the God of the Bible created the universe and all life. Christians disagree, however, on how God created. Young Earth Creationists believe that God created just 6,000 to 10,000 years ago and disagree with much of mainstream science. Supporters of Intelligent Design accept more of evolutionary science, but argue that some features of life are best explained by direct intervention by an intelligent agent rather than by God's regular way of working through natural processes. We at BioLogos agree with the modern scientific consensus on the age of the earth and evolutionary development of all species, seeing these as descriptions of how God created. The term BioLogos comes from the Greek words bios (life) and logos (word), referring to the opening of the Gospel of John. “In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made.” (Updated on March 1, 2012)

Genesis 6-9 tells the fascinating story of Noah, the Ark, and the Flood. Some Christians interpret the text to mean that the biblical flood must have covered the entire globe. They also work to explain the evidence in rocks and fossils in terms of this world-wide flood. Other Christians do not feel the text requires that the flood be global, but could have covered the small region of earth known to Noah. The scientific and historical evidence does not support a global flood, but is consistent with a catastrophic regional flood. Beyond its place in history, the Genesis flood teaches us about human depravity, faith, obedience, divine judgment, grace and mercy.

In recent decades, scientists have discovered more about the beginnings of humanity. The fossil record shows a gradual transition over 5 million years ago from chimpanzee-size creatures to hominids with larger brains who walked on two legs. Later hominids used fire and stone tools and had brains as large as modern humans. Fossils of homo sapiens in east Africa date back nearly 200,000 years. Humans developed hearths for fire, stone points for spears and arrows, and cave paintings by 30,000 years ago. By 10,000 years ago, humans had spread throughout the globe. Genetic studies support the same picture. Humans share more DNA with chimpanzees than with any other animal, suggesting that humans and chimps share a relatively recent common ancestor. Also, the same defective genes appear in both humans and chimps, at the same locations in the genome—an observation difficult to explain except by common ancestry. Genetics also tells us that the human population today descended from more than two people. Evolution happens not to individuals but to populations, and the amount of genetic diversity in the gene pool today suggests that the human population was never smaller than several thousand individuals. Yet all humans, of all races, are descended from this group. Humanity is one family.

In recent decades, evangelical Biblical scholars have reconsidered non-literal interpretations of Genesis. The Accommodation view of St. Augustine and John Calvin is supported by recent discoveries about ancient cultures. Literature from these cultures shows interesting parallels and differences with Genesis accounts. The differences are striking, such as stories where creation is a battle among many gods rather than the acts of one sovereign Creator. The similarities, however, show how God accommodated his message so that the Israelites could understand it. For example, the Egyptians and Babylonians thought the sky was a solid dome. This solid dome appears in Genesis 1 as the firmament created on day 2. God did not try to correct the “science” of the Israelites by explaining that the sky was a gaseous atmosphere. Instead, God accommodated his message to their cultural context. Many evangelical Biblical scholars have concluded that Genesis is not meant to teach scientific information.

A common argument against biological evolution is that the theory contradicts the second law of thermodynamics. The second law says that disorder, or entropy, always increases or stays the same over time. How then can evolution produce more complex life forms over time? The answer is that the second law is only valid in closed systems with no external sources of energy. Since the Earth receives continual energy from the Sun, the second law does not apply.

Many arguments claiming to prove the existence of God have been proposed throughout the centuries. The response to many of these arguments, however, is: “If God created the world, what created God?” It suggests that certain arguments for God’s existence only push the question of beginnings one step farther back. The Bible and Christian doctrine address this question by defining God as eternal and uncreated, but such answers rarely satisfy nonbelievers. A philosophical response is that God is the ultimate first cause; the atheist is left with a dilemma of what or who that first cause might have been. In the end, an uncaused creator may simply be a more plausible explanation for the universe we live in. Our universe appears to have had a beginning, to be finely tuned for life, and to have a place for love and purpose. These appearances affirm as plausible a prior belief in God.
