More than 90% of world population believe in one or more religions, only based on artificial traditions, unproven beliefs, empty faith, dogmas, myths, brain washing, mass behavior, social manipulation etc... zero facts, zero evidences, zero proofs, zero science etc. Therefore, no surprise people also believe in weird stories about aliens.
And here I don't even question whether aliens exist or not. Aliens are not the problem! The problem is to deal with aliens as a kind of religion, creating weird alien stories... zero facts, zero evidences, zero proofs, zero science etc.
And I go further! Maybe aliens exist, and also maybe there are interactions between humans and aliens. I just say that all these "alien documentaries" are like religion... zero facts, zero evidences, zero proofs, zero science etc.
My mind is totally open to the possibility that aliens exist. But my mind cannot accept the lack of evidence or the lack of scientific substantiation of these fake documentaries.
I repeat, the problem is not "to believe in something" (Religion, Creationism, Flat Earth, Weird Stories About Aliens, blah blah blah)... the eternal problem of the majority of the population always is to "believe in something" with zero facts, zero evidences, zero proofs, zero science etc.
