The one thing that science has trouble explaining is how different cultures in vastly different parts of the world tend to share stories with the same themes, gods, creation, floods, the wipeout of civilization and rebirth of an advanced civilization following some sort of rules.
I find it interesting how the Myans, Jews/Christians (Old Testament), Hindu, Greeks, Romans, Egyptians, Far East religions, the aborigines, and many other ancient cultures not only tell the same type of stories, but have very similar accounts of them.
Some are obviously influenced by others (like the Bible/Babylonian which are from the same area), but how can the aborigines have so much in common as the Babylonians and the Central America cultures?
Again, not proof, but food for thought.
This is a neat little chart showing all the different flood stories and similarities between them.
