Gee, where did they get that idea?
The possible answers to that are not seriously addressed in this more-ways-than-one frustrating podcast with Ross Douthat of The New York Times.
... Douthat: When people report having a telepathic connection, you said they get information from, or they feel like they’ve gotten information from, these experiences. What kind of information do they get? What does that mean when people report this?
Pasulka: A lot of the people would report the information as something that had to do with the future. They would have ideas of basically an apocalypse, a bad scenario for the future.
The people who I talked to at this conference were pretty convinced that we were going to face some type of cataclysm. So I talked to them a little bit about how people have thought that for about 2,000 years. [Chuckles.] ...
Pasulka: It appears to be a perennial thing. So there appears to be something that interfaces with humans and has been identified in the various traditional religions.
Douthat: Identified as what?
Pasulka: Well, I’m not going to name it, because in some traditional religions it’s named in different ways. So it could be bodhisattvas, angels, demons — things like that. ...
The whole thing is here in "What if the Government Believes in U.F.O.s More Than You Do?"
If you are looking for a religion scholar to say that the UFO cult is a human creation just like every other religion, you won't find that from Diana Walsh Pasulka, a practicing Catholic who wants to argue for the legitimacy of mystery and of people's experience of that mystery, even if they work for a government which cannot be trusted on UFOs.
It is telling that a member of a hierarchical religion which is imbued with deference to authority finds the belief in UFOs among government employees somehow more compelling than that belief among private individuals:
... they have various titles. They have quote-unquote “day jobs” as, say, a mission controller at Cape Canaveral, things like that. And almost all of them called it this: They said, “my hobby job.” They would call it their hobby.
Elites also run in herds.
