Some say that Noah's pre-Flood world was like Pangaea. The Book of Moses seems to say otherwise.
In Moses 7, Enoch sees a vision of a battle "many generations" in his future--a battle which, for many reasons, complicates the simple global-Flood model that so many people adhere to.
In Moses 7, God promises Enoch that part of Noah's seed will be found "among" all nations. Evidence that more than 8 people survived the Flood?
There are mainstream scientists and biblical literalists... and then there's the Pearl of Great Price.
