I'd assume unverifiable but narratively meaningful theories like multiverse theories, "the universe is a hologram", etc fill that role nicely. Sci-fi is full of them. "New Age" beliefs are what you're looking for at face value, of course.
Thanks. Thought of these. I wondered if anyone has taken it a step further and created new gods (of the hologram, of the multiverse, etc) beyond the metaphysical/new-age trend towards "the self as god". I suppose Roko's basilisk true believers and their AI god counts.
some have said - since we are ultimately, just humans.. inquiry has to fit what a human is able to see-hear-think etc.. so human-centered inquiry took over the public process, over time. Humans are dangerous predators so, not being attacked by other humans while doing whatever is a non-trivial aspect of growth over time.
