OK, sorry for getting this thread off-topic, most people probably don't want to read this here. One last thing to say on the subject. I'm pretty convinced that the aliens and night terrors that people encounter are actually encounters with fallen angels. Evil still tries to manifest itself and just takes on new forms through the years. Demons, djinn, gremlins, aliens...all the same thing. There was a fictional book I read that was a little dry and awkward, but explained the phenomena pretty well.
Nephilim by L. A. Marzulli. I don't buy into everything in the book, but it does a pretty good job of explaining the ideas. Check it out from the library if you can. Just doing a Google search for "nephilim" will give you some intersting reading. Check out the beginning of Genesis chapter 6.
