I saw a UFO maybe 12-13 years ago. It did not look like anything a human would design, even with advanced technology. It looked something like the oblong silver blob in The Flight of the Navigator, just hanging there, "much in the way that a brick doesn't." It must have been 5 km away so it would have been pretty large. It was a breezy overcast day with low clouds, and the moving clouds obscured but never completely…
Same here it’s always always like that as if the ufo has an earth camera detector, I fathom it may still be technically feasible if they are advanced enough. This would explain why nobody has had a clear picture taken of an UFO. /sarcasm
A bit later I was at lunch, and my phone turned on with 40% of the charge still left.
Realistically, it was some weird drone and a failing battery. But if I allow myself to dream for a moment, that was an alien UFO.
