I was gonna comment on ESR's post and I wanted to reference something in the epic of Gilgamesh when I found something AMAZING.
The epic is written on 12 tablets, the eleventh is about Gilgamesh talking to Utnapishtim, who tells him about a flood that happened and how he was ordered to build an ark and all... It's like the story of Noah.
You can read tablet 11 here.
If you think about it, it's written thousands of years before the bible and there's no way that the people who wrote the bible have read it, how can you explain the similarity?
Atheists, take it as a challenge!
