I was pondering this today after spending a few minutes browsing some subs I frequent. It seems like many people are very quick to offer dubunking explanations for everything. Even if someone takes a video of clearly evident uap/ufo activity and says stuff like "there were 3 of us that saw it and it did xyz thing over a span of 30 minutes" people will still say stuff like it was a bird, a plane, a balloon, starlink, venus/jupiter/mars, a floating grain seed, drone, or insect. I honestly believe that people have been conditioned somehow to reject the possibility of anything not of this Earth. I believe even if a reputable agency, individual, or government came right out and said that ETI is real and exists, people would not believe it unless aliens landed on the White House front lawn or right out front of 10 Downing Street.
I don't know if it challenges peoples' world view or religious view or maybe their thoughts on what is and isn't physically possible. It's somewhat concerning. If regular people hold these beliefs strongly then who is to say that some authority figures do as well? What if behind the scenes these adamant individuals are so upset at ETI existence that they are planning to attack them or something? That could have really bad consequences if the ETI don't play nice. Of course this is assuming that what we are witnessing is even ETI. I remain open to the possibility that what we are observing isn't ETI, but I'm about 75% sure it's not of Earth.
