You should. There is no agreement even among creationists on the date of the supposed flood:
2252 BC -- layevangelism.comBut none of this matters, as science has found no evidence that a global flood actually occurred.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
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 flood is mostly regarded as being around 4300-4500 BC dont care what other sites you put up there if it is looked at biblicaly and archeaologists and historians who have studied and scholars agree that the over all date is around 4300-4500 BC, there is always gonna be someone with some adhock to throw in there but the best evidence is and mostly regarded date is 4300 -4500 BC. And to add the evidence is overwhelming to a global flood.
