For example, the phenomenon of flying saucers (UFO), which spread widely in the sixties, there is a lot of talk about it that it was a superior American military inventions since that time and people thought when they were seen as creatures from space through flying saucers.
So for me, I wouldn't exclude that this was also one of the superior American military inventions that defied the laws of physics known to us.
That likelihood of being another superior American military invention is very high. With our technology right now, they can build something that is not deemed possible. But sometimes it is interesting to watch and read all these conspiracy theories.
I like this one though. I think you've used this image before as I already saw this.. But yes, this maybe the case here also.
no where in any of both images does it prove beings from another planet
even the top image can only prove 'object that cannot be identified'
