We have a literal deluge of evidence now (Sorry I couldn't help myself) that shows that a large flood did indeed hit the Mediterranean area around 8000 years ago. Funny.
You will notice around the Black Sea large clusters of cities and population centers that were last above water around 8000 B.C. The same is true in the oral traditions of many indigenous Native American tribes around the Great Lakes region in the U.S. and Canada. Notice how these stories originate from a time when the glaciers were receding and melting, those millions and million of gallons of water have to go somewhere.
People need to remember that the bible relies heavily on metaphor, simile and recycled symbolic imagery. The biblical flood myth is simply based off of an older Babylonian flood myth - The Epic of Gilgamesh. Which in all likelihood was based in part off of a real flood. But it was just that, a flood, not a divine act, but simply a misunderstood geologic process, like so many other instances like this.
