You sound as though you have a very rational position. Show me some evidence before I believe something. I agree very much with that attitude, but I have to admit I'm inclined to think something is there for two reasons, the universe is pretty big, and I can't agree that every single sightin[g] is a mistake.
Obviously, I don't know whether or not some of the phenomena described as UFO phenomena are the result of extraterrestrially built spaceships appearing in our skies. Some might well be. But the likelihoods, as currently understood, appear to be against it. And, of course, if there are no alien extraterrestrials in our spacetime vicinity, there are a fortiori no abductions of human and animals by alien extraterrestrials.
In short, I just don't know what's going on with respect to some of the more well-attested reports of UFO sightings, and I'd like nothing better than to run across some really hard evidence which bears on the question.
When I invited my psych class to view the program tonight, one student stayed after.
She had grown up on the farm ajacent to the farm where a cattle mutilation had occurred with--I believe a large craft--huge cigar shape, I think. I forget. Anyway--there were 8 cattle involved--typical organ removal and NO--ABSOLUTELY NO blood left in the cattle nor on the ground. None.
AND NO TRACKS of any kind other than the cattle to the site where they were abducted.
How would you explain that?
