I agree. One cannot logically believe in the literal, all-at-once (6-day) creation story with zero Darwinian evolution, and at the same time believe the literal story of Noah's ark. To do this is to assert that every species alive today (besides sea creatures) exists only because it lived through the flood on the ark. I don't know how many species are claimed to exist today, but I'd bet it's orders of magnitude more than could live several months on a boat built by a small number of men over a few decades. Either the flood did not destroy all land life or evolution occurred after the flood. What do the strict creationists say about this?
