More than likely that there as only one continent before the flood. See hydroplate theory which connects more dots and makes more sense than plate techtonics.
Of course. Pangaea broke apart after the great flood which I believe is alleged to have occurred roughly 5K years ago.
An event that all accepted principles of geology and physics demand must have taken place over a period of billions of years, actually happened in what - several thousands years. Yep, that's believable.
Sorry, I'm going to have to stick with the accepted theory of continental drift. I'm crazy that way.
