As a historian and college professor, I've been doing that for decades, dear. In fact, most atheists of my acquaintance are well-educated, thoughtful people who have actually made a study of other cultures and beliefs. It's one of the reasons they are atheists: they are quite well-informed.
I think I can guarantee you that I know considerably more about those topics than you do.
The reality is that the better educated you are, the more widely read you are, the more likely it is that you will be an atheist.
