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.

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.

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.
