For some, yes, it is a religion in the same way as certain religious sects view the world. No evidence, wishful thinking, "feelings" of other beings, supposed sightings, etc. This would seem to be the polarized, out-there, faith types that refute any type of useful investigation.
On the other hand believers and non-believers have had experiences. What these experiences are and what they mean remain elusive. Take the sightings of Phoenix and Hudson Valley. It certainly seems something was seen, by lots of people. What was it?? I don't know, I didn't see it.
It seems that we do have some types of evidence. I'm reminded of the Ted Phillips trace case in I believe Kansas. With the boy who saw this object and the family that saw it as well. We have pictures of the "ring" left behind. We have samples that were taken. Seems to have been a UFO, meaning something unusual and undetermined.
We also have documented evidence of things like Hessdalen and Marley Woods where "something" luminous and strange is not only seen, but documented.
Then, of course, we have David Bowie's Starman. The observant benevolent creatures watching over us. Absolutely no proof. Not entirely implausible, but quite a jump from something that you might think of when talking about ufo-logy. "Ology" usually meaning the study of something and not the wishfulness of it.
The spectrum of what we might call ufology is so vast that certainly some of it likens to religion no doubt. And some of it is rather interesting and perplexing. And even with the so-called evidence cases as descibed above and others it doesn't seem to indicate that we are experiencing some vast transcendant intelligence, but that we may be experiencing something that is misunderstood or more likely in many situations misidentified. Even so, I could be wrong, and we could be experiencing something of intelligence. I just haven't seen that myself.
It's an interesting question as there are certain parallels depending on the observer.
BTW thanks for changing the thread. I was trying to determine if people were in the closet on such subjects like I am. And it turned into this, which is fine. Thanks
