I think Noah's Flood was the Black Sea flood and that is dated at 7,600 years ago. (Noah's Flood,Ryan & Pittman). I suspect that a lot of the dates we have accepted as correct are in fact wrong and should all be further back in the past. I read sometime ago that one guy thinks the dating problem is directly related to errors in the dating of the Egyptian 'Kings List.'
Plato said there had been many floods. I made a mistake, by the way. If the Exodus was 1560 B.C., then Noah's flood was ~2352 B.C. (not 2200 BC.)according to what I was thinking.
