Isn’t earth millions of years old? Common dating methods used to support this idea include analyzing ice cores, counting varves (sediment layers), and radioisotope dating. How do these methods work—and what assumptions do they involve? Let’s think about it.

What would have to happen for life to arise naturally from non-life? Let’s begin thinking through just some of the steps required. Along the way, we’ll see how to separate facts from assumptions in “origin of life” studies, including the famous Miller-Urey experiment.

Let’s continue thinking through the steps that would have to happen for evolve naturally. We’ll look at the popular “RNA world” hypothesis, which claims that life first evolved from RNA-like molecules, and see why even some evolutionists now argue this would have been impossible.

A fatal weakness of creationist arguments is said to be that environments change over time. “After the changes,” this objection states, “living things are no longer adapted to the environments they were originally designed for, so their designs are no longer good. This reality doesn't fit with th...

Are aliens and UFOs real? The idea of life from other planets has captivated popular culture, but isn’t a concept you’d get from the Bible so much as from evolutionary assumptions. Let’s apply some biblical critical thinking checks to see what research really reveals about extraterrestrials.
