That's good. You stopped believing in UFOs. Think back, it probably wasn't hard.
It is also easy to change other beliefs.
It is easy not to believe that vaccines are safe; not to believe pharmacons care about your health; not to believe your gov loves you. easy!
Then you are free to believe nothing.
My friend, I do not believe in Pharma, our president is accused of drug dealing by the New York Southern District Court. i do believe COVID does exist, friends of mine who were completely healthy died of it, at home not in a hospital, at least some of them. I also have no problem with vaccines, I don't believe in a chip in them. As for UFO's I said I used to believe in them, now I don't entirely disbelieve but I do have doubts about them being alien, you know, it is so far to travel those distances just to watch us. On the other hand I do have doubts about how scientists can be able to measure distances that they can not prove at such perfect detail, you know, that star is 120.9 light years away. Don't think I am just a gullible person because I believe in COVID. If you don't I am OK with that, you can of course believe whatever you want and who knows, you might be the one who is right.
