UFO doesn't mean "alien", it means
UNIDENTIFIED FLYING OBJECT. That means it's something flying, and you can't identify it. Simple. It may be an airplane, or a duck, or a Chinese balloon, or any of a number of other things. But if it's
FLYING, or appears to be
FLYING, and
YOU CAN'T IDENTIFY IT, then it's an
UNIDENTIFED FLYING OBJECT. By far and away most "
Unidentified Flying Object" reports are later
identified as
airplanes. Who'd a thunk that, right? Not space ships, not flying saucers, not demons, not "orbs", not anything cool like that at all. Just boring old airplanes. "Oh, but did things that Defied The Laws of Physics". No, it didn't. The laws of Physics are part of God's design, and nothing violates them. If someone says something
did, then that someone isn't a trustworthy observer.
So the Navy pilots shot videos of
flying things they couldn't identify. That's all. Not aliens, not evil robots, not demons, not ghosts, just UFOs -
flying things they couldn't identify
So what were those things? Dunno, couldn't identify them. Maybe Chinese drones. Maybe reflections of something somewhere else. Maybe some kind of natural phenomenon. Demons? Possibly, but is there any particular to believe that? Scripture doesn't tell us about demons doing anything like that. Aliens? Why do we have any reason to believe in aliens at all? There's no evidence. For most people who believe in aliens it's a matter of faith, a kind of goofy religion, to be believed without proof.
Occam's (or Ockham's) Razor: Also known as the principle of parsimony. "Nature operates in the shortest way possible." (Aristotle). In other words, the simplest answer is the one most likely to be true. So if your UFO could be: A) aliens in a flying saucer, B) demons trying to dupe you into believing they're aliens in a flying saucer, C) a hallucination caused by the the CIA trying to dupe you into believing that demons are trying to dupe you into believing they're aliens in a flying saucer, or D) an airplane you couldn't see properly. Occam's Razor requires you to shave off everything but the simplest and most parsimonious answer as the most likely - it's an airplane. Not much fun in that, and nothing there to get your blood up, but let'd face it, the mundane, everyday world is like that, init?
Yeah, if you have a lot of emotional capital invested in demons and aliens Occam's Razor is gonna prove disappointing to you, but life's full of little disappointments. Demons probably don't whiz around in flying saucers; no reason to believe that they do. There probably aren't aliens bothering Navy aircraft, since there's no reason to believe that there are any aliens at all. I suspect I know, based on an Electrical Engineers knowledge, of what the Navy's "UFOs" actually are, but engineering stuff is usually only exciting to engineers, and almost no one will be interested in how those "sightings" may well be the products of modern technology and not magic. I mean, where's the fun in that? And parsimonious old hybrid Korean-Redneck that I am, I'm betting that neither demons nor aliens had a doggone thing to do with the "Nimitz Incidents".
