If you could create a supernatural reality that people could believe in what would it be?
A few ground rules:
What you are creating is actually the truth, not just what you want people to believe is the truth. If your religion says hell exists, there are actually going to be people there suffering.
The truth you create has be be compatible with the reality we observe, so if you create a omnipotent, omniscient benevolent god, you are going to need to explain why bad things happen the world. The only allowed change is that you can make it so that a large percentage of the world believes this truth.
On the other hand your religion doesn’t have to survive Occam’s razor. It just has to fit the observed facts, not necessarily be the most likely explanation for them.
Bonus points, if your religion can explain something that is currently not understood by science, or if it leads to every treating each other better.
The universe was made by god out of boredom and curiosity. He created it and its physical laws, but more or less lets it run on its own. To experience his creation he moves his consciousness successively between all sentient creatures, but at each time temporarily forgetting all but the knowledge and understanding of the body he is currently inhabiting. Thus all sentient creatures are really just one soul (god), and any actions we take that causes another to suffer is really hurting ourselves. Of course some of our selves are less wise than other parts so it makes sense to take precautions, say imprisoning those whose state of mind would lead to more suffering if allowed free reign.
