Something is very clearly happening with this subject, and it has been systematically ridiculed or put in separate categories of thought and no one is stopping to ask why.
There isn't something "clearly" happening with the subject of UFOs and aliens. UFO reports are people seeing weird lights in the sky and not understanding parallax. Do some people report direct contact with alien beings? Sure. But some people also report contact with angels, demons, leprechauns, bigfoot, and any number of other otherworldly phenomena. It's really not that complicated. People hallucinate and dream things, often based on pre-existing cultural exposure. There's very few people on Earth at this point that haven't seen depictions of a big eyed grey alien. And since everyone has seen these depictions, when people end up in altered states of consciousness through mental issues or psychotropic substances, that image serves as feedstock for their visions.
Yes, claiming that otherworldly beings are visiting us and interacting with people IS an extraordinary claim. It's something that would redefine our entire worldview and our understanding of our place in the universe. And we don't accept those types of claims based on flimsy and unreliable eyewitness testimony.
The most damning piece of evidence against UFOs and alien encounters is that the quality of visual evidence for these phenomena hasn't increased at all over the last 30 years. Every UFO is still an out-of-focus blob, and that's because it's only out of focus objects that can be mistaken as alien spaceships instead of ordinary objects like planes and balloons. And despite everyone now having HD cameras in their pocket, no one has ever managed to get a clear video of one of these grey aliens that are supposedly constantly flying around and fucking with people.
The quality of evidence for alien visitors is, from a scientific perspective, absolute dogshit. It's not repeatable. It's not reliable. It's not in a form that can be interrogated and examined critically.
Do you know what it took to get people to accept the heliocentric model of the Solar System? The exact opposite of that. It took multiple independent lines of evidence that could be independently verified. Galileo didn't say, "I have observed that the Earth goes around the Sun, and you'll just have to trust me." He said, "here are my pieces of evidence A, B, C, D, and E, here is my method, and if you build a telescope like mine, you can repeat my experiment and confirm everything I've done myself." And even then it took centuries for the heliocentric model to be accepted completely!
I'm sorry, but fuzzy out of focus dots and unreliable eyewitness testimony (often produced under hypnosis) is just absolute shit-tier evidence. And no, the recently military videos aren't any proof either, as they're also out of focus crap and clear parallax errors.
