There is truth everywhere. And there are lies everywhere.
It boggles the mind.
For example, not wanting to go back to the topic, but just as an example, the Earth is actually flat, as long as you go fast enough in orbit. This all according to relativistic physics. But mainstream science fans will never tell you that, because they don't fully understand it, they focus too much on little details that are easy to grasp.
So yeah, there are crumbs of truth here and there in every theory, in every domain of knowledge too.
Same for religions. Who are the gods and prophets that manifested themselves in the past? People fight over them because of inconsistencies, sometimes just apparent ones. Any sufficiently advanced technology is indistinguishable from miracles, correct? This should be easy to be figured out by the majority, but they're not even close to questioning these things, they only follow "the program".
I believe there is a physiological problem with the human brain.
