People today ignorant of geologic processes say it’s impossible that a flood covered the whole earth, and tribesmen anciently would be put in that category too except for the fact that over six hundred tribes from around the world repeat legends about the global flood, passed down from their ancestors, so were those ancients actually all in unison fantasizing about a global flood or are all the tribes actually descended from the eight people who survived on Noah’s Ark? Refer your friends please to the Page at right Natural Selection by Noah’s Flood to understand the dynamics of the flood and its implication for natural selection by the genetic bottleneck at that event.
