Deny the supernatural, people become insane. It is so obviously untrue.
"When a man ceases to believe in God, he will believe in anything." Just look at the worldlings around us. They are desperate for meaning, mystery, and "something more" than the boring physical world, which is clearly not the cause of its own existence. Whether it's ghosts, reincarnation, the Mandela Effect, simulation theory, true sentient AI, outer space/aliens, parallel universes or dimensions -- they know there's something more out there. And the thing is, they're absolutely right. There is a whole world of the supernatural, which they are ignorant of.
Freemasons won't allow anyone to join who is an atheist. An atheist is a degenerate moron, and they know it. Anyone who denies the supernatural needs to have his head examined. They insist that their members believe in some sort of higher power. Think: Deism.
Of course, the higher ranks learn that their god is actually Lucifer.
Nevertheless -- the devils are not part of the physical world. Moronic atheists don't believe in the supernatural at all. Not in God, angels -- or devils.
