I think people like Dr. Greer were allowed to see things, and then let to formulate their own ideas. Why, maybe it is a form of preconditioning.

Did you know that the creator of star trek Gene Roddenberry, was a airforce pilot in ww2 and spent a decade investigating plane crashes for the military. The shit he must have seen, I feel like some of it may have bled out into his show.

I do think that if they came out and admitted that we were created by these higher life forms, that most forms of modern religion would collapse, causing mass chaos and panic. Judging how stupid the average person is, thanks to our leaders who dumbed down the education system, fed us poison, and bombard us with billions if not trillions of ads during ones lifetime. I believe modern society as it is would likely collapse.

Humans feel this need to control and subjugate everything, including each other. The idea that there are beings far more powerful than we can contemplate, well I cant imagine it would be good for most of the people.
