I said I'd get to this sometime. When Noah was SIX HUNDRED YEARS OLD God told him that, although the rest of civilization were full of sin, Noah was perfect; thus, Noah was instructed to build a 450-foot boat. With eight people.
When the Ark was ready, two of each species were loaded on. (Where he got penguins in Israel I don't know. Presumably he took the smallpox virus with him as well.) Then God made it rain for forty days and forty nights. Which would make quite a puddle. Whether the entire Earth would be swallowed up by that is doubtful. Where Noah got water for all the animals I don't know either.
My point is that the Bible shows large marks of human creation. Although hardly anyone believes this story, my question is why anyone believes the other ones.
