Billions of worlds and countless religions are in the universe. We can't be the only Third Rate Planet that buys into The Fraud God. And they're all invisible too. Some brilliant people believe we may be a software program. Quantum superposition, states there can be two identical particles in two places at the same time. So maybe we're on someone's laptop; they're lapping us up as I type...Or a long forgotten program or game that is in a universal trash dump somewhere? One thing for sure it is not an invisible man sitting on a Throne deciding who gets to live or die.
Billions of world's seems true based on the calculations. Countless religions would be based on countless sentient species. That's less certain. We can't assume, even if there are, that they follow religions, though early species development perhaps suggests that might be true. Who knows -- maybe we are a slow species and other planets have beings that cast off religious nonsense much earlier than we have. It would be good to know, however.
If we're on someone's laptop, are you really typing? And wouldn't the owner of the laptop actually be a god to us?
