global flood at about 4,300 years ago
I have no opinion on a date for a/the flood. Hydrology is still in dispute over simple things like the age of Niagara Falls and the Mississippi/Missouri river to start stating "without a shadow of a doubt" any ages. The best we/they got are SWAGS (scientific wild a$$ guesses) and general assumptions or time frames. To put exact dates on things that old without irrefutable evidence reminds me of the Leakeys, et. al. When facts are supposed to guide science, why so often does science try to guide the facts? It seems that the hardest thing for a scientist to say is "I don't know."IMO.
Actually, science has placed no date on a global flood, as there has been no scientific evidence for such an event at the appropriate time. Hydrology, geology and other sciences don't come into play.
The date of the global flood, as estimated by biblical scholars, is given variously as:
2252 BC -- layevangelism.com
2304 BC -- Answers in Genesis (+/- 11 years).
2350 BC -- Morris, H. Biblical Creationism. Grand Rapids, MI: Baker Books, 1993.
2370 BC -- TalkOrigins.com
2500 BC -- http://www.nwcreation.net/biblechrono.html
2522 BC -- Dr. Gerhard Hasel
2978-3128 BC -- http://www.asa3.org/archive/ASA/199605/0162.html
3300 BC -- http://www.biblediscoveries.com/flood1.html
3537 BC -- Setterfield (1999)
The most common date is in the range of 2300-2350 BC, so I used 4300 years ago in my post #252.
To repeat the point of that post, the genetic continuity from 10,300 years ago to living individuals that has been documented in the western US agrees with other evidence that there was no global flood at about 4300 years ago.
