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.

In this video, physicist Ard Louis describes that our value and purpose do not come from whether or not we were created by an evolutionary mechanism. Evolution may tell us something about how we were created, but it is not the source of our worth.

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.
