@Pythagorean,
Oh boy...I can't vote (poll lacking fullness). I like to maintain, as much as possible, an image of being a (I'll call it '
healthy') skeptic here. Yes, the term, most unfortunately, is bad--
U.F.O. There have been filmed and photographed '
craft-like' flying objects which seem to suggest something of a kind of intelligent operation which (as mentioned somewhere above) though very few (relatively) cannot be explained easily at all. One such visually captured case happened in Japan, with up to a hundred or more viewers.
However, life forms (beings) from elsewhere in the universe can not yet be determined from these . . . as best I know at the moment. I used to be a believer, but am now far more skeptical than not. So, I do believe there have been flying '
craft' sightings which cannot be explained--or haven't been explained (governments can be secretive, you know)--because of the record of them on film, but, I have no reason to yet agree to think (regardless of that movie about what is said to have been happening in the far north of Alaska [was it?]) that there is life as beings from else where in the universe visiting us here on earth in such a secretive, Men In Black fashion.
