I've long suspected the reason that all videos of UFOs are smeary/unclear is because if they were clear, we would be able to see which kind of aircraft it is in the footage, and it wouldn't be a UFO (but an air balloon, commercial aircraft, glider, etc.). One thing that is certain is that if no alien air crafts have ever visited earth, then all UFO videos/pictures must necessarily be unclear, because otherwise we'd see that it's not a flying saucer.
