Evidence from the Black Sea does point to a slightly more recent date - say 7600 years ago.
Geologic evidence?
If so, then there's a discrepancy of 1400 or so years.
And according to sevenbak's interpretation, which somewhat agrees with what I've heard over the years, the great flood occurred 2500-2300 B.C.
So, it's better to say that we don't really know when the flood of Noah occurred, isn't it?
