What Do You Think UFOs Really Are?

well i'm still a bit skeptical of aliens, but i seriously doubt it would be the military, it just doesn't make sense to me. i also don't think it would be god related, why would anything concerning him look like a UFO? i strongly disbelieve time travel. i'm skeptical of other dimensional travel, but i like the theory. i can't really think of much else it could be, but although i'm skeptical, i think either aliens or extra dimensional beings.
