This seems to me like a categorical error. You speak about proof and facts, which are ultimately connected to the scientific method. Scientists often say “There is no evidence, that this happens/exists” (that phrase is important) and will disregard it, until there is evidence. That doesn’t make them close minded. Changes in knowlege are applied when they arrive, not through speculation without evidence beforehand. That way we can approximate the truth in our physical world. There is no scientific evidence of a god existing, so scientists disregard her, until such evidence appears.
Now you could say, that a god would exceed the physical limits of our world/existance. But then the whole scientific method becomes useless (as how would you get scientifical evidence for something outside of the scientific world) and you cannot speak about facts or truth or proof. This is the realm of belief, not science. And it will stay this way until a god would bridge over this devide.
So i would say: When talking about science, proof and facts, you need to stay in the reach of the scientific method. When talking about something outside of its reach (metaphysical), then its belief. Even you talking about the possibility of a god is a question about belief.
An interesting customer base might be small communal organisations. At our local scouts troop I had a discussion with a friend, who is also in IT. His idea (not fleshed out) was to provide small local organizations with a stack of already configured open source software to support the typical needs of such organizations (like a wordpress website, a nextcloud for file storage and common calender, limesurvey for surveys and event registration, mailman3 for mailing lists,…). Depending on the needs you could sell the initial setup process (your personal work in setting up and skill transfer) or ongoing support. Though such organizations normally don’t have much money to give away. So probably its not really worth your time financially (though probably really appreciated in the community).
