UFO?

It's not UFO it's people from the future. Various fractions keep on trying to change their past to their liking.

Why would aliens want to come to such a hostile planet, with hostile inhabitants who can't stand each other? I'm sure they call Earth ''Green Hell''.

Extraterrestrial ufos have only a liminal kind of existence. Always just out of range of a good photo. Somehow we project them, their purpose being to draw us ‘out there’ not to become solidly real enough to visit this joint. 

When I was in primary school, I had three friends, two of whom didn't get on. Friend 1 came to school one day with a photo of a UFO he claimed to have seen. Friend 2 said it was a lump of blu-tac stuck to the window. I defended Friend 1 because A) I knew Friend 2 picked on him a lot and B) because I'm a gullible autistic. Anyway, weeks or months later, Friend 1 admitted it was a fake and I felt an idiot.

My friend philosopher has a theory that Earth is a prison planet, and there are aliens in their ships parked in orbit, making sure we don't escape. I support him everytime. It's enough to say ''You never know''.
