Err what about the The Epic of Gilgamesh, produced by the Sumerians?
Sources of Gilgamesh predates any sources of Genesis. Fragments of the Gilgamesh flood story have been found on tablets that date beyond 2k B.C! The Epic of Gilgamesh is the oldest known work of literature.
Gilgamesh has many parallels to the Noah flood. Some like to claim that since the Gilgamesh story is cruder (not by much) it is obviously a "corrupted" copy. However one would expect earlier versions of a myth to be simpler and later copies to be more refined and complex as the result of cultural advancement.
Nice example of a meme!
As another example of meme replication, there are several parallel verses and key concepts of the Epic of Gilgamesh in the Greek epic poem of the Odyssey. More refined and complex!
