There's a reason why for all those stories about a great flood: pre-civilization humans were passing down stories of actual witness accounts of massive flooding caused by the melting of the massive ice caps at the end of the last great Ice Age about 12,000 years ago.

I mean think about it: when those ice sheets--which may have been at minimum just over 1,000 feet thick at the higher latitudes--melted, the melted water had to go somewhere. Modern humans--homo sapiens sapiens--have been around for circa 150,000 years, and they were certainly around when the last of those great ice sheets melted, flooding huge swaths of land.

...pre-civilization humans...

You're making presumptions. If Scripture is true, then such a term is meaningless. "civilization" only makes sense in the context of a multi-million-year-old Earth and the brutal macro-evolution that the Godless claim had to have happened to bring civilization about.
