Seriously though, I would love to see one, with detail, not so high up in the sky where you really can't tell if its a bird or a plane, or superman, but close enough to tell.
While I personally have serious doubts about UFO's, I do keep a open mind, and would be more thrilled seeing a real space ship then seeing a boring ghost. But the odds are greater I will see a ghost.
Speaking of odds, wonder what the odds are of aliens visiting earth and spotting a ghost, and mistake it for the typical life form here. Imagine their attempts to abduct a ghost to probe them! Even worse, imagine they encounter a possessed soul by some demon, and they try to probe it. BTW, whats with all the probing any way? If they are so much more advanced then us, don't they have any IF or Laser noncontact instruments yet?
Any way this could be why we have never had official contact yet or been invaded. They fear us
Now why doesn't Hollywood think like that?! Would make a great horror/sci-fi flick.
ET Meets Freddy! (guess who gets probed)
