I really don’t think so.
The sedimentary layers that are many meters thick and that persist for hundreds of miles in four compass directions (with no erosion damage between layers) are a powerful testament to the validity of a literal worldwide flood.
Just FYI, I am 100% in agreement with the idea of a recent worldwide deluge, and about 95-99% in agreement with a young earth theory.
I don't expect to change your closed mind, but to help convince other Christians that Morris does not have the final word on Biblical text, and certainly not on geology.
Worldwide floods have happened many times. There's geological evidence for them. There's plenty of evidence for the area in question being under water for millenia; the layers alone (as you cite) are testament to that.
But there is NO EVIDENCE linking either to Noah's flood.
Noah's flood was NOT global; it was only "worldwide" in the sense that the whole known world of mankind was affected.
How do I know? There is no way Noah's ark (for which we have the dimensions) held all present-day species of animals, in all parts of the globe. And unless you're willing to go to the kook fringe of the young-earth movement and posit super-efficient macro-evolution to generate all the present-day species, which is otherwise anathema to young-earthers, the limited scope of the flood must be admitted.
Morris (along with his collaborator, Whitcombe) was looking for a way to support the kooky dreams of Seventh-Day Adventist prophetess, Ellen G. White. There is nothing Christian about it.
