I watched the movie Zeitgeist, and it blew my mind. I had always had suspicions about religion's historic beginnings (not Genesisitically speaking). Now, I'm not one to throw my entire opinion on to the information brought forth in one documentary/conspiracy theory, but through much research on my own, I believe religion is the human attempt to understand things that are beyond modest comprehension. Now we have science--tho' it not always be perfect--to explain and prove stuff to us. We are afraid of death and the unknown, hence the creation of a Supreme Being that makes everything okay.
