Yes, but your comments are independent of what actually transpires in the cases of contacts of UFO’s and the like. The phenomenon is very much like claimed encounters with supernatural creatures. It’s loony tunes stuff.
I don't doubt that a lot of it is, but there are hundreds of thousands of solid, down to earth people who've given sober accounts of witnessing flying craft that can't be explained as being of terrestrial origin.
I'm not going to call those people looney tunes. Who am I to tell them that they didn't see what they saw, or that they must have been hallucinating?
I can choose to disbelieve their accounts, but I'd never tell some trained and experienced pilot who's seen a UFO that he's out of his gourd. All I can do is take his story at face value and try to compute the probable validity of his story with what details he gives me.
I think the trouble UFO witnesses run into, is that they've just witnessed something that goes so far outside the realm of ordinary human experience, that it invites disbelief. And you know - I can't fault anyone for not buying it. I suppose it's something that any one of us would have to see for ourselves to gain the same kind of certainty that witnesses have.
