I doubt extraterrestrial visitors are behind UAP reports. I suspect it's secret aircraft tests and human imagination adding nonexistent details to misunderstood sightings.
Have you ever seen someone completely misunderstand something fairly mundane, like the flat earthers who refuse to understand how cameras work? Now add science fiction cultural influences and crazy people to the mix alongside deliberate obfuscation by governments and corporations.
I'm cynical enough to assume any "disclosure" is another layer of coverups and distractions for the benefit of Lockheed Martin, Boeing, etc.
Skepticism is good when it comes to this kind of thing. My gut tells me it's a mix of both "ours" and "theirs" I'm just not entirely sure who they are.
I understand what you're talking about. I've heard that native people of South America couldn't even comprehend what the Spanish ships were when they arrived on their shores in the 1400s because they didn't have a frame of reference.
