Absolutely, absolutely, I believe that. No doubt at all about that.
(not sure about the 4200 year figure, though. Never been an issue with me, as far as the time it occurred, I just know it did)
My sources for the about 4200 year figure are:
2252 BC -- layevangelism.com
2304 BC -- Answers in Genesis (+/- 11 years).
2350 BC -- Morris, H. Biblical Creationism. Grand Rapids, MI: Baker Books, 1993.
The problem I see is that in the western US where I work (as an archaeologist) we have an unbroken series of radiocarbon dates from numerous occupation sites that span that period. There is no sign of a flood of the necessary magnitude, no sign of disruption of occupation sites what would occur with a flood of that magnitude, and continuity of mtDNA across that entire time period.
Okay, I see. You may be right. That is a good website for reference. All I know is that the Bible states the earth was completely covered, so there must be an valid explaination to what you are seeing. I would think 'Answers in Genesis' might have helped you on that?
Why don't you write 'Answers in Genesis' with your question? I would think they may be able to shed some light on the subject for you.
That's because the devil kept that ground dry to fool you, and you are doing the devil's work.
