==Ummmm, Im pretty sure you were the one posting the article with the 450,000 year old dating, right?
From the article:
“Within the evolutionary (long-age) timeframe,
the first flooding event is believed to
have occurred about 425,000 years
ago during the Ice Age. In my view,
however, the first erosional event was
the receding water of Noahs Flood [3]
(~4,500 years ago, Genesis 8) cutting a
deep canyon through the landbridge that
then connected Europe and the British
Isles, a structural ridge known as the
Weald-Artois anticline made almost
entirely of chalk.”
My apologies. I am talking about the graphic you posted in #5.
