If it pleases the court, I would like to introduce exhibit A:
This, along with several other edited pieces of film circulated for many years on social media as a "would you ride these amusement park rides?" Millions of people for two decades completely skipped the logic and physics and just instantly accepted that this was real. Maybe one in a thousand of us realized that this was completely implausible horse E36 M3. Some engineer actually did estimates on the G-forces that humans would experience and it was something like 36g. Seeing as how every bone in your body breaks between 8-10G, and you pass out at 4-6G, they estimated that the humans in those cages would have disintegrated as their bodies ripped through the cages like a jellyfish in a net.
That, of course, assumes you can deny the fact that those G-forces haven't already ripped the ride's car off those toothpicks that supposedly articulate at acclerations not possible while displaying no mechanical means of articulating.
So when it comes to UFOs, I don't think it could possible be advanced military technology. A new radio frequency that gives you a headache, maybe. Violating the laws of physics? No. Is it an alien space ship? Possible. A forged piece of film? Likely. Advanced technology from earth? Not a chance. I can believe that the gubmint has plenty of technologies that we don't know about, but straight-up violating the laws of physics isn't one of their talents. As soon as people start believing in things that are implausible without giving it any critical thinking, it becomes a conspiracy. I have a family member who is a nurse and she refuses to get any vaccinations because she it convinced that they have a microchip in them. She has believed it for so long, and even after she became a nurse and realized that infused vaccines are typically administered by a needle that measures 0.008" in diameter and she is the one filling the syringe from a vial, she still believes that somehow the government knows which syringe she'll grab out of the drawer, which vial she'll grab from the fridge, which syringe she chooses, and somehow guides this microscopic piece of electronics to its home in your body where (despite its impossibly small size) can implant suggestions in her brain and make her do the bidding of government. She believed something implausible, clung to it as fact, and even after learning all the reasons why it couldn't possibly be true, she still believes it.
UFO is just unidentified. In this video below, our brains go nuts thinking it's aliens because even this seasoned Navy pilot can't tell what it is. In reality, it just means he/she didn't identify it. For all we know, later in the day they found out that Jim got drunk and stole an F16 for a joyride.
The entire conglomerate of human brains is a funny thing. I'm a scientist, but also an artist. Psychochemically speaking, we're all wired differently. The way we assimilate new data to formulate new truths is all different.
Mathematically speaking, I do believe there is life on other planets. It might be a bacterium, or some completely different thing altogether. Maybe that life originated not using DNA or cells at all. Maybe there are planets full of humanoids that look really similar to us. Don't know. But all of the speculation we humans do about it is (to me) comically earth-centric. We assume it has a form, or made of cells, or has a language, or space travel. We might find an entire planet of Boron-based life forms that are just piles of magnetically-charged powder.
Many of us laugh at the notion of "little green men from mars" as antiquated and comical that the last generation believed that, but seriously... what many of us believe today is the same thing. The reality could be that there is nothing out there, or it could be that it is all out there and we couldn't possibly be able to fathom it because we're too busy looking for life as we know it. We look for water and single-celled organisms on other planets. What if life there doesn't need water or cell structures?
Is there life out there? Mathematically it's almost impossible that there isn't. But math isn't life. Will it show up as 6000 planets with half-naked humanoids that follow greek society like Star Trek would have us believe? I highly doubt it.
