And people actually believe this stuff. A lot of people, too. When debating Christians at Sierra College I found that, when directly asked, most Christians believe in either the literal Noah’s Ark Biblical account, or some strange variation of a global flood. Facepalm.
For a great thrashing of flood geology I recommend chapter three of Donald Prothero’s Evolution: What the Fossils Say and Why It Matters. While this video gives the common sense reasons the story of Noah’s Ark and a global flood are laughable at best, Prothero gives a detailed scientific account of why, from a geologist’s/paleontologist’s perspective, flood geology holds no (figurative and literal) water.
