Perhaps evolution needs its own 2LOT, an argument or evidence (or two or three) that disproves flood theory for anyone regardless of how poorly they understand science. It would differ in nature from the creationist 2LOT argument only by being accurate and correct.
Ya know, Percy, this might not be a bad idea either for this thread or another, more focused one. I haven't read through this thread in its entirety yet, but I see this as a valid objective for the "sci-guys" to attempt. I personally like the genetic bottleneck and biogeography approaches, but that's 'cause all rocks look the same to me. Maybe we should/could explore this further?
