Worldwide flood, eh? Whodathot.
There's PLENTY of evidence that such catastrophies have occurred during the existence of Modern Man; it BEHOOVES US to discover when & How these events occurred--& WHY they occurred!
I, personally, DON'T want to "start over again in the 'Stone Age!'"
We DO NOT undestand the "History of Man" over the past 10 Millenia very well!
