The theory I like best on that is earthquake that caused the Mediterranean Sea to suddenly burst through into the Black Sea, flooding the then "civilized" world where cities existed.
It was about the same time period.
No. I think the source of "Noah's flood tale" is called the Bible.
MacNoah?
Could this be the source of the Noah's flood tale?
Yes!!! It was a recounting of a dream Noah had after drinking too much mead.
It's possible this contributed. It is certainly old enough, but the effect itself wouldn't have reached the Mediterranean. Who's to say how the story would have spread, they might have put this together with the [possible] flooding of the Black Sea and various other disasters and said --look, this seems to have been widespread, it probably covered the entire planet. The Internet hadn't been invented yet by Algore, so they had to rely on traveling merchants and minnesingers for their news: a little harder to piece things together that way.
A tsunami would've crushed the ark, plus tsunamis don't last for months.
