No one knows when the flood was. including the Biblical scholars whom you like to quote. So your insistence of selecting a date is only a red herring so you can go trot out & say that you found no evidence of a flood at that time.
Also it is easy to notice that you try to place people in a double bind by the way you present your replies when there could other answers. Why is it easy to notice? because you do that in almost every answer you give.
It is obvious that you have an agenda and you are obsessed with certain topics. And since scientists and researchers have been known to cook their data and salt the sites, I find your conclusions in those areas suspect and unconvincing.
By the way the topic of this thread is or was 'problems with evolution' not anything to do with the flood.
