NOT TRUE, AT ALL!
When researched, more than 90% of all UFO sightings prove to be AIRCRAFT, or or natural aerial, meterological, or astronomical object that have simply been misidentified.
Let me holler this again - 9 of 10 UFOs are NOT demons, are NOT angels, are NOT paranormal, and are in fact boringly normal. Sorry to spoil anyone's fun, but that's the facts.
Ah, you say, but what of the 9 to 10 percent of UFO sightings that CANNOT be identified? They must be demons!
Well, no. The remaining unidentified flying things remain - unidentified. Why? Because there's simply not enough data to determine what they actually were at all.
Could they have been demons? Possibly, but that isn't the way to bet, is it? We know from Scripture that there are demons, but there is nothing whatsoever in Scripture to lead us to believe that demons zoom around in flying saucers "deceiving" folks. On it's face, it wouldn't seem like a very effective way to deceive anyone, especially whe people in general seem so keen to beieve that any flying thing they can't recognize is a demon anyway.
Could they be flying saucers flown by spacemen? Possibly, but we have no evidence to lead us to believe that there are any spacemen at all, or flying saucers for them to fly in if there are. You're free to believe i them if you like, but it's a matter of faith, since there's as much evidence that spacemen don't exist as that they do; none at all. Zero. Not a shred. Zilch. "Oh, but Bob said aliens took him to their planet on a flying saucer." Right. And I'm Czar of All the Russias.
On top of that, the 9-10% of UFOs that remain unidentified are so due to lack of data. Which means that the odds are very, very, very high that they're all airplanes and such themselves, we just don't enough data to say for sure. Evidence again. Absence of evidence that something is not an airplane is not evidence that it's something spooky; Occams Razor still forces us to say it probably is. Nothing at all leads us to assume that it's either spooks or space dudes. Nothing. At. All.
The Christian Faith isn't based on creating fantasies and calling them true, and we ought to stop it.
