The casual dismissal of UFO's may be wishful thinking, engaged in by people who cannot face this awful possibility. There have simply been too many detailed stories, for too long, from too many witnesses. The attempts to explain these sightings in some other manner are, generally, almost laughably weak.
Equally dangerous is the assumption that we should be seeking out aliens through the government-funded "Search for Extra-Terrestrial Intelligence" or SETI. As has been pointed out, contact between an advanced civilization and
a far more primitive one has usually or always, in human history, been devastating for the primitive culture. In the context of extraterrestrial contact, that primitive culture would be US, folks. Think about it. And that's even apart from the possibility that the advanced civilization might actually be hostile.
You are scaring me! There are so many of us, I will just maintain a very low profile and they will miss me entirely.
You are totally correct in your thinking. More than you realize. And stay tuned, especially you nay-sayer know-it-all types out there and in here!!!!!!!!!!!!!!
One of the most amusing explanations has been that the sightings could be attributed to "swamp gas."
Much agree.
I do think that many are loathe to allow the possibility because it would alter their very willful/hedonistic/perhaps rebellious lifestyle.
