Either way that you look at it, there's no proof that it's not from beyond and there's no proof that it is. It's a draw. It can't be proved or disproved. I'm skeptical of it, but it's still possible. I think there's an afterlife, for instance:

See the section on near death experiences. Really interesting and true (Discovery Channel had a program on about life after death; ALL 10 of the patients who had been dead for various periods of time and then revived reported floating above their body, heading through a tunnel into a light, and being met by a voice). Strong evidence since 2 of the people interviewed were Atheist and honestly said they'd never believed in God. I don't know if he's the God that every religion wants him to be. In fact, I think all religions are wrong, but something does exist when you die. I don't believe in God (too much pain in the world; then again, maybe he's just watching us and doesn't interfere), but experiencing my own NDE would probably change my mind.
