Everyone suddenly forgot they had 4k cameras in their pockets
This is what kills me. Hundreds of millions of people have access to advanced cameras that take exceptionally clear pictures/video yet not a single person on earth has a clear definitive shot of anything that could pass as extraterrestrial. If folks were arguing these beings can't be seen or understood via human comprehension then that would be a different thing. Instead the common UFO argument is that these beings are very visible, very present, and we have all types of evidence thanks to...low quality Air Force surveillance footage.
Do I think aliens exist? Yes. There are too many planets out there where life could potentially exist. Do I believe aliens have visited earth? No. Assuming we're talking about a technological civilization, the energy required to reach our galaxy would be so astronomical we'd be talking about a civilization that is literally light years ahead of us. We would be nothing to them, and our advancements would be like comparing an ant farm to a B-2 bomber. They'd be able to effortless exterminate us if they wanted. So I'm gonna assume they haven't made contact.
