Evidence for God from Science

Do you know where I can find resources on the early post-Flood cultures? I'm talking about things you don't find in normal history books, because I have those -- I was wondering if there's a link between early cultures and biblical accounts. (Pre-Flood would be nice too, but as it was all destroyed, it's only of limited importance.)
OEC or YEC doesn't really matter.
One good site I know about is Ancient Days, which might give you an idea of what I'm looking for.
