Starting my own religion, here's an explanation of it
The Simulation Assertion is a religion designed to accommodate our understanding of nature. Therefore, there are no issues with creationism or metaphysics to make a case against any of the events or places depicted like there are with all other religions, so it doesn't necessarily require unsupported evidence or faith. It is designed specifically so that it can either be validated or falsified by the scientific method. In other words, a faith in facts that can potentially be proved, that is a goal of every other religion, to have content that cannot be refuted anymore than can any other scientific discovery. But nothing in science is irrefutable so we have to be careful, the scientific method is a tool to understand nature as it is, without credulity or bias.
The Simulation Assertion acknowledges the simulation argument, and introspectively calls into question the motives of the simulators. One of is that the universe that we experience as self-aware intellects is a simulation of a universe with the same fundamental physics and that it was designed to test human nature.
Anthropocentric beings, that is either a group of human or cybernetic post-human programmers, or a singular artificial sentient programmer, manipulate this reality to the extent of empowering a human individual with the means to let his or herself be used to help humanity at large once that individual becomes aware of a divine influence. Conversely, the simulation's operator or operators manipulate this reality to the extent of empowering a human individual with the means to use others around himself or herself to the extent of using others to help himself or herself achieve self-centered wishes once that individual becomes aware of a divine influence.
