I once saw a UFO. I don't know if it was extraterrestrial but I'm willing to keep an open mind. The author of this isn't, he's already made up his mind. UFOs were either hoaxes, man-made objects (aka aircraft) or misperceptions of natural phenomena (ball lightning). People who believe in aliens are either delusional, psychotic or stupid. I wanted a discussion of the topic, but the author was only interested in his side of the story. 2 🛸🛸
