So, what say you, HN? Of the multitude of UAP's that have been reported, some percentage (I don't know the number off-hand) have not been identified as having benign / prosaic origins. Of that chunk that have yet to be explained away, what do you think they are?<p>Some obvious options would include:<p>1. totally benign / prosaic things like planets, weather balloons, satellites, stars, airplanes, helicopters, etc. that simply weren't able to be identified because of lack of information, etc.<p>2. Optical illusions<p>3. Advanced technology deployed by another Earth based entity (private entity or State-level actor, possibly even including elements of our own government / military)<p>4. Advanced technology deployed / controlled by extraterrestrial intelligence(s) aka "little green men from mars" or what-have-you<p>5. Some kind of previously unknown natural phenomena<p>My own guess is that if we had perfect knowledge, we'd find that the vast majority are category 1, with a small handful represented by categories 2 and 3. I consider it extremely unlikely - but not impossible - that some could fall into category 4.
