Point: UFO = Unidentified Flying Object. I believe that there are objects that have been seen in the sky, whose nature is unknown. Whether they are of terrestrial or extraterrestrial origin remains unspecified. If they were identified as alien spacecraft, they wouldn't be "Unidentified", now, would they? Belief that there are objects whose nature we do not know does not equate to belief in extraterrestrial visitors. (FWIW, I believe that there are other intelligent lifeforms out there. To insist that we're the only one seems supremely arrogant. I also believe that any species intelligent enough to build a ship that could travel here is wise enough to avoid contact with us.)
