There is no reason to believe that, at all.
Except for, of course, the Bible authors' documented histories of plagarisim and borrowing, sometimes even from each other.
Other than a consistent history of plagarism, no, there's nothing to indicate that they may have plagarised a legend. Of course not.
But, we have nothing that should lead us to believe so.
Aside from the obvious physical impossibility of the story, which would be a dead giveaway for most persons, and has been, throughout history.
And yes Nuggin, the whole world descended from Noah and his family.
Right. Because Noah was simultaneously black, white, native american, asian, polynesian, middle eastern, and all the other races of man. He would have had to check more checkboxes on the Census than Tiger Woods!
Ah, right. And every person in every civilization is decended from Noah's family; including those civilizations that existed concurrent to the "Flood" time and, mysteriously, recorded no distruption in their cultural development or record of artifacts. Weird, that.
