Here is another bit of evidence for you to deny: A partial skeleton was found in a cave in Southern Alaska. mtDNA was extracted from a tooth. It was also dated to 10,300 years. The mtDNA turned out to be of the haplotype D4h3. Something like 46 living individuals stretching along the west coasts of North and South America have the same haplotype. If there was a global flood, in the intervening time those individuals would have the same haplotype as individuals in the Middle East and Mediterranean. They don't. There is continuity of this mtDNA type in the Americans during the time the global flood would have resulted in a discontinuity.
That is a very interesting piece of evidence. I agree that it is a show-stopper for a global flood in that time period.
If creationists cannot deal with this type of evidence, they cannot honestly continue to accept any global flood. (I suppose they will continue to do so. They will just be dishonest in doing so.)
I am curious: what is the longest human continuity you know of, including all types of physical evidence, such as those you have mentioned in these forums?
