What I want to know is, the ark landed on a mountain top, and all the world was flooded, and somehow the carnivores stopped eating meat and walked a few thousand miles home and propagated an entire race using just one male and female without inbreeding.
Somehow, the reptiles didn't freeze up on that cold mountain. Somehow they all swam home, all to N. and S. America, Australia, Asia, Africa. Somehow, the 3 toed sloth which can only live in a tree and eat a certain leaf (same goes for Koala) found their way home. Somehow they made it pretty quick, as there are no fossil records of any marsupials in the Mount Ararat/Iran area, or any pandas, sloth, anacondas, tapirs, orangutangs, chimpanzees, gorillas, Thompson's gazelles, warthogs, or any of the hundreds of thousands of species.
But, I'm just trying to apply logic to a fable, the sad thing is that some folk embrace fables as if they were they were the truth because they were written in a book after generations of hand me down stories.
Dim folk.
By the way, who in world are you to limit God? Are you suggesting the God is incapable of what is described about Noah's Ark in the Bible? Or, are you one of those genuises that has made the blindest leap of faith of all and tells himself that there is no God? Talk about clinging to fairy tale.
That's where people like us go wrong--trying to apply the logic which supposedly God gave us to stories which supposedly God gave us.
Here's logic for you.
Perhaps the mountains themselves, i.e. high ground, served the function as the arc, and not a literal boat.
In this scenario, those species that could make it to high ground survived, and the rest sleep with the fishes.
