The evidence of a coastal beach far below current sea levels in the Black Sea is solid. The Flood theory, well, not so clear.
There are PULSES of ocean level rise of quite significant size ~ one is at 14,000 years ago, and another occurs in the 11,000 year ago period, then one as the Younger Dryas melts in the North (about 9500 years ago), and another one about 7500 years ago in various spots (Black sea) and China Coast, and West Coast of South America ~
These things are all easier to understand if you can come to grips with the idea that Modern Man and his civilization is really, really, really recent! Otherwise this planet was a desolate wasteland of vast dusty deserts and icefields (for the most part). Then, all at once it became a place of fertility and warmth.
I wholeheartedly agree.
I had read, several years ago that the flood event in the Black Sea area could possibly correspond to the dates of the flood mentioned in the Bible. Wasn’t there a flood mentioned in the “Epic of Gilgamesh” as well, taking place around the same time?
