Reply #37: I don't know that that's so idiotic.

[InvisibleTouch]

My personal jury remains out on ghosts, but there's no logical reason to believe we're the only technologically advanced life-forms in the universe - or even that we're anywhere near the top of the ladder. What I don't think is that aliens are so fascinated by mundane little old us that they routinely visit and study Earth - but I have no doubt that they're out there, and might buzz past every now and then as they go about their own business. I would go so far as to say it's more idiotic (not to mention completely arrogant) to think we're "alone in the universe."
