I am leaning on the idea that Aliens are actually Interdimensional Beings.

Maybe these fast movements of ufo light are actually luminous beings from another reality... and that they're playing with us humans on Earth, all these ancient alien theories are actually buildings, tech and methods brought to us by extradimensional entities. So far we've only seen microbes in space. And the Crop circles aren't reused by these aliens as airports or spaceports. mb these are creatures or beings that have outlandish tech and vehicles from another dimension. some just land on earth like a UFO on sci-fi would. kind of like on Mortal Kombat or one of those early 2000's anime.
