Quintessence I have about the same belief that you have.

Unless the theory that we all derived from aliens is a possibility. Before you laugh me off the forum, just think about it for a second or two. They come here, snatch some, test them. Bring them back. Now if they werent harvesting us.... why would they bother bringing bodies back? Why would they even take us in the first place? What would us, as dumber than average humans in comparison to them possibly learn from us?
