Schizophrenia is what Mohammed suffered from, which caused him to think Allah was talking to him. In actuality, his brain was malfunctioning due to Schizophrenia.
The brain is a storyteller for the conscious experience, and yet the deeper that rabbit hole goes into creativity and analysis, the more discipline is necessary to turn away from it and delegate to the unconscious.
Furthermore, a lack of evidence for gods does not mean that scientifically there are no gods. The only way for things to be disproven definitely is through mathematical proof. Because this cannot be shown in a mathematical proof (there is no mathematical way to represent godhood) the concept of a god cannot be definitely disproven in scientific approaches. Otherwise the most scientific claim is merely "we cannot find any evidence for <concept>" with the logical step being that therefore <concept> doesn't exist or has a low statistical chance of happening- but this is a cognitively easy conclusion and not what science is actually doing.
Science and the scientific method is actually extremely limited when dealing with the concept of dieties. It can only say that, given claim X, experiment(s) were run that did not verify X. After enough experiments are run, they are evidence X is not true. But none of these are absolutes, and claiming a mountain of evidence is a definitive scientific proof is itself unscientific.
True, but it implies the need for skepticism, especially given how many people have desperately attempted to find said evidence. Depending on your outlook it might also imply that a degree of disinterest in warranted, because the world of “things for which no evidence can be found or is required,” tends to be enormous and frankly, not that interesting. Unless we’re very specifically talking about a god who will damn you for a lack of faith, then ignoring the whole issue seems like a safe bet, and when you die you either learn the truth, or you’re just dead. It’s not like a human can do much either way, again, unless your assertion is about a specific and judgmental god.
Tl;dr I think the whole god thing is even less compelling and worthy of attention than the Bermuda Triangle. It’s just another thing that’s possible among an infinity of possible things lacking evidence for their existence. That’s pretty boring.
Self-help is one of the best selling genres, yet the most simple of which has been known to man for thousands of years.

Bonus points if x is human-readable text.
Perhaps schizophrenia is a functional mutation that introduces cosmological insight to a group of people; the witch doctor/seer archetype, for instance.
It's obvious that deities are (as of yet) born of un-falsifiable hypotheses, although thank you for pointing that out...
