The BioLogos Forum is pleased to present this infographic about the tools scientists use to determine the age of the Earth. The graphic, titled "How Do We Know the Earth is Old?", uses data compiled and summarized by geology professor Dr. Gregg Davidson.

I find that when many Christians think about the way God created our universe, 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.

“That just doesn’t sound right.” 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.

In this three part series, geologist Stephen Moshier critiques John MacArthur’s articles on uniformitarianism, while offering an alternative perspective on the principle. He exposes faulty conceptions about and misleading definitions of uniformitarianism. Gregory Bennett further defends the idea of an old earth as Biblical and focuses on the unchanging nature of God. He also discusses the Scriptural doctrines of creation and God’s providence.

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)

In this video, 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 argument.

In our sixth BioLogos videocast, we take a look at the age of the Earth. We explain four methods scientists have used to determine that age: tree ring, lake varve, radiometric, and seafloor spread dating, and also offer some theological insight on how an old earth can fit with the first chapters of Genesis.

We've recently been looking at the evidence for an old earth and the long history and vibrancy of this view among evangelical Christians. Today’s post features a preview of the updated Question, “How are the ages of the Earth and universe calculated?" revised by Senior Web Consultant and Writer Deborah Haarsma.

This series discusses the importance of unity among Christ’s believers. Ross Hastings, an expert in the areas of both chemistry and pastoral theology, is eager to see the church seek out unity rather than divisions in this science/faith interface. Unpacking Ephesians 4:1-6, he explains that unity in Christ through the Holy Spirit is the primary concern of both Jesus as seen in John 17 and Paul in Ephesians 4, making this matter pressing. He urges all believers to be in agreement that God indeed created, yet to be in dialogue over how that creative process occurred.

... I would exhort these, my fellow conservative evangelical shepherds and thinkers, to set aside all reticence and fear, emerge from anonymity, and storm the forum of discourse, engaging this most pressing matter with vigor, equanimity, and humility. In doing so, know upfront that there will be few handrails to guide; you will not be building upon an extensive precedence of published conservative thought.

I look my students dead straight in the eye and tell them that no matter what, debate within the intellectual sphere cannot and should not take away or diminish the importance of the personal nature of their faith. The intellect, to use a scientific phrase, while necessary for the faith, is not sufficient

In this excerpt from the book Delight in Creation: Scientists Share Their Work with the Church, astronomer Deborah Haarsma shares her excitement about recent findings about our universe from a Christian perspective.

Gregg Davidson and Ken Wolgemuth seek to remove the stumbling block of the Genesis flood in this four part series. Though many believe in an ancient world-wide flood, the evidence given does not hold up to geological scrutiny, but points rather to something regional instead. It is their hope that Christians will not walk away from faith in Christ simply because a global flood is not supported by science. Looking at natural phenomena like the Grand Canyon, salt beds, and fossil deposits, they reveal reasons for these deposits and structures while showing that their origin did not stem from a violent flood that covered the planet.

Our desire to engage in gracious dialogue with fellow believers who reject biological evolution has been receiving increased attention in both the Christian and secular press. More importantly, we are being joined in this reconciling project by our brothers and sisters in Christ who have often been defined primarily as our “opponents”.

At a press conference on July 4, 2012, and with 99.99994% confidence (5 sigma), CERN announced the discovery of a particle consistent with that of a Higgs boson (a.k.a. “the God particle”). This is very exciting for elementary particle physicists. But what is the Higgs particle, and what is its meaning?

The discovery of the Higgs boson would certainly be a breakthrough for particle physics and cosmology, but would such a finding also radically redefine theology’s understanding of God or challenge the existence of such a deity? Is there actually any theological or religious significance in Higgs physics at all?

This series by Scot McKnight relates a lecture given at the 2012 BioLogos workshop for Evangelical theologians, scientists, authors and pastors. He explains that evolution is taught in public schools, and therefore must be addressed by Evangelical pastors in the churches as well. This will educate a whole generation of upcoming scientists on the issues of science and faith. Overall, he encourages scientists and pastors to collaborate on the issue as they rethink the long held interpretations of Genesis 1-3.

Baylor University Physicist Gerald Cleaver describes the changing state of our understanding of the cosmos and suggests ways that Christians can make theological sense of a theoretical Multiverse.

Because evolution is a challenging subject, many Christians are tempted to simply ignore or reject it. Yet considering evolutionary creation has important benefits for Christians both in our relationship with the Creator, and with our relationships with other people—believers and non-Christians alike. First, Christians should study evolution because (like all the natural sciences) it is the study of God’s creation. Creation itself is a complementary revelation to what is communicated in the Scriptures, and through it God shows how and when he brought about life, to his honor and glory. Studying the creation is also an invitation into a deeper understanding of the attributes and character of Father, Son and Spirit. Second, considering evolutionary creation aids the Church in its gospel mission, supporting young Christians in their faith, helping answer critics, and equipping us to engage effectively in the wider culture. An anti-evolution attitude can harm Christian young people by presenting them with a false choice between pursuing science OR holding to faith. Similarly, a hostile attitude towards evolution can hinder evangelism when seekers hear that they must reject science to follow Christ. On the other hand, studying evolution as a God-ordained process helps Christians refute arguments that science encourages an atheistic worldview. Furthermore, as the church engages front-page issues raised by the rapid growth in science, medicine, and technology, a Christ-centered voice in such areas as bioethics will be stronger if based on a thorough understanding of the natural sciences, including evolution.
