Warning: History Geek alert!
OK, now the warning is out of the way I can continue :o)
I mentioned in the comments to my last post that the story of Noah and the Flood has parallels in other Ancient Near Eastern literature besides the Bible. For those who are interested, here are a few parallels to biblical stories in other Ancient Near Eastern texts, which you can look up if, like me, you find this sort of thing interesting. The links will take you to online versions of the texts.
Biblical passage: Genesis chapters 6-9
ANE parallels: The Atrahasis Epic, the Gilgamesh Epic and the Sumerian Flood Story
Biblical passage: Psalm 104
ANE parallel: The Great Hymn to the Aten
Biblical passage: Proverbs 22:17-24:22
ANE parallel: The Instruction of Amenemope
If you want to learn more about the Ancient Near Eastern documents here, information about all of them should be available on Wikipedia.
