@oldgraymare2 Some people say that they are just life-forms that live in our atmosphere.
Others say that they are organic UFO’s and more or less just misunderstood animals.
Then there is the idea that they are psychic vampires… This is based off Gnosticism and ET conspiracy theories.
They call them Archon’s and if you Wikipedia that you get a few definitions of what Archon’s are by heretical gnostic cults.
The name and ideas have been incorporated into UFO and extraterrestrial conspiracies.
I didn’t read the whole article it’s too out there but you get the general idea.
