Speaking of myth, there is more here and now evidence for the Biblical myth than for the evolutionist myth, as depicted by your mythical map.
How do you
know that your god didn't want there to be an inland seaway and geologists are just discovering what happened? Does that somehow contradict what the bible says?
By the way, "my" map has multiple lines of evidence leading to its conclusion. Independent researchers have corroborated it as well. There isn't any need to develop an inland sea conspiracy, because it has nothing to do with evolution. All that was required was that researchers follow the immense body of evidence and draw there conclusions on what it meant.
