In this video conversation, Jeff Schloss makes the observation that when we use the term “evolution”, it is not always exactly clear what we are actually discussing unless we denote the intended usage.

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.
