What have you witnessed or seen that would sound like a conspiracy theory if someone else told you?

I saw UFO's. I don't want to believe in aliens, but I witnessed it when I was with a pretty big group of friends and we all remember it and none of us have a better explanation. The people who saw it first were outside smoking pot, the rest of us didn't believe them until we went outside and saw it ourselves. I was sober that night fwiw. We tried recording it but no one's phone had good enough dark recording to pick up anything, and no one had a real camera on hand. The flight style didn't match any craft any of us knew of - it was an array of lights that moved together, and then separated into smaller groups, and eventually individually. They moved unnaturally, with near-instant acceleration, deceleration, and extreme direction changes. It was too high up to be likely to be drones or helicopters, and right above a major Canadian city, not near any military base. If this was, like, Nevada or something, I would assume it was a government test craft. The closest match I've ever heard was in an interview with a pilot who saw UFO's, and that scared the shit out of me. I'd love to find a non alien explanation, because I don't want to believe and also I know it sounds crazy. Like, I myself probably wouldn't believe someone else telling me this story.
