No shocker here! We all know that Tom Cruise is a member of the Church of Scientology, a group that believes alien souls find their way into human bodies. Tom -- who planned to build an $11 million bunker in 2007 to protect against an invasion -- has said, "Are you really so arrogant as to believe we are alone in this universe? Millions of stars, and we're supposed to be the only living creatures? No, there are many things out there, we just don't know."
