"What about people experiencing a divine being communicating to them, then?"
But we have studied this and the answers tell us what the most realistic thing actually is and thats why we see 'divine being communicating to them' as a mental illness.
You can expierence this challanging thought yourself by taking LSD. Realizing that you are actually know everything for a few hours and than getting back to your 'normal reality' is exhausting.
But i still don't believe we are all caught on the earth and we need LSD to shackle those bounds. I know how many people are on the planet, how many people i have seen die and leave our planet in the normal rational way. I have never ever seen anything which makes me believe otherwise and LSD showed me even more how fragile my own reality is.
You might want to look in a medical book on different topics you refered to to see what you believe. Nonetheless its just more realistic that human a had a similiar brain issue than all other similiar independend cases before than that this person is now talking directly to god and we areound us are all dumb shits not being able to recognise it.
My default sentence for this is simple: I'm a good person, and i don't like the idea very much that there is a god who allows cancer in kids and rape from religious people and murder etc. and either this god is a massive asshole, clearly not relevant enought to woreshop or doesn't exist anyway.
