I don't believe anything when it comes to alien interaction with earth - if aliens exist they haven't visited earth IMO. That being said, the description of their religion is rather chilling when you consider the implications. No interest in individual life, focused entirely on the gradual creation of a spiritual soul field that can communicate with them. Which would suggest they'd destroy all life on earth to harvest the souls.
Yeah that guy's post comes off as bs.
The problem though is that once you open the door to legitimately say that yes the earth is actually being visited by aliens then *everything* is on the table: Reptiles, Tall aliens, android gray aliens, Christianity was started by humanoid aliens, christ was an alien that was never actually crucified it was just an illusion, alien reproduction vehicles with human tech and alien tech combined, a galactic wide star trek federation kind of does exist that's also keeping close tabs on humans to guide their development, "they" want to be observed by us in their ufos to influence our evolution without directly contacting us, etc...
Regarding religion I've read elsewhere that souls come from a universal intelligence that "they" (i.e..humanoid aliens) call the unnameable because no name can encompass it.
And there are possibly an infinite number of universes so ours is just one of many.
Also the gray aliens aren't even biological they're more like robots which is why they act so weird. And they're built by human-like aliens that appear like us.
But it makes sense because if you're exploring a dangerous planet you wouldn't show up in person like a star trek episode you'd send androids in your place.
