Where am I getting this information? (Of course, I was lumping deluded people in with liars.) The slippery answer is that you are free to name anybody honest, who has God speaking through them. The more general answer is that any lying bastard seems free to start a cult or religion, and I surmise that in a universe that God genuinely did not interact with, these manipulators would be hard at work, creating religions, to exploit the desperate and gullible; so it would look no different to our own religiousphere, where you propose that a God really does interact [or matter] within it. I derive this from the conflciting diversity of religions on this planet, that have evolved.
I have to disagree with you there. In the universe you described (or one with an absent deity), all
of the cults/religions would have had to be started for gain/exploitation, or out of delusion. I don't see on what basis you can conclude that such a universe would be identical to our current one.
For instance, if we imagined a universe were all lawyers were greedy, it's a bit of a hasty conclusion to say that such a universe would be identical to our own. Sure, we could cite the average salary of lawyers or their stereotype as greedy, or point out that greedy people are free to become lawyers, or even sample individual lawyers, but we don't know whether the outliers would change the universe. If 4% of lawyers are not greedy, we could easily get a >95% sample and conclude all lawyers are greedy, but that could still result in a vast difference between a universe with 96% greedy lawyers and 100% greedy lawyers via the butterfly effect.
Similarly, I don't see how the mere existence of diversity in religious belief is evidence that our universe is identical to one where all religions were founded on delusion or deceit. Especially with many religious beliefs being so ancient, it's impossible to say what the result would be. Hinduism, for example, is nearly 4000 years old. How can we predict how our world would be different depending on whether the original Vedic writings were based on legitimate experience or fraud? How can we say that Christianity would be exactly the same if Jesus was liar, lord, or lunatic? Or Islam's Muhammad, for that matter? Or any other religion with its founders?
It should come as no surprise to you, that I think that the evolutionary shaping-forces on religion are what the adherents want to believe, rather than what the silent God actually wants; so, the religions should converge, in universes where God does not talk to us.
No, that does not come as a surprise to me. But as I don't believe in a deistic god, I don't believe God is silent, so I don't reach the same conclusion.
A horrific thing might be, if a God really did talk to us, and we found out how he wanted something entirely different to what we had wanted. He might for example say, "I don't like you. I want you all to die." We might reply, "We don't like you, and will continue to love each other, and do our best", to which he might reply "Go ahead, it's pointless; I will kill you all in the end, anyway." That might be a real God talking, so it's just as well he leaves us alone, to invent shit.
How does that prevent Yougod from being omnimax? He becomes irrelevantmax.
God going all Marshall Brain on this universe kind of contradicts being omnimax. I don't see how a deity could fit both being omnimax and your description.
