No it doesn't, and several working geologists have debunked that myth on this site over, and over again.
I have also posted evidence from my own research which does not support a global flood between 4,000-5,000 years ago.
Short version: we don't need geology and fossils, that time period is illustrated perfectly in soils!
We can date Native American occupation in the western US using a variety of methods, and there is a continuous record of occupation, improving subsistence and settlement (except where hampered by climate change), fauna and flora, artifact styles, mtDNA, etc.
The reason we don't see posters refuting this data, other than "it can't be so because I believe otherwise" is that the creationist websites are all focused on the evil Darwinists with their fossils and geology.
Don't need no stinkin' fossils! The record of the soils is enough all by itself.
THERE YOU ARE!!!!
Am I a great straight man or what?
