There's a bit in one of the early episodes of the TV series "The Good Place", where one of the afterlife people points out that pretty much every religion only gets a few percent right about what's going on (except for one random guy who somehow got 90-something % of it).

But yes, this is the thing that always gets me. It takes a mind-blowing amount of arrogance to believe that your religion -- out of all the thousands that currently or used to be practiced -- is the right one, and everyone else -- billions of people -- just absolutely must be wrong.

And if you don't have that arrogance (but are nonetheless religious), the only reasonable stance to take is that you believe there is a god, or many gods, or perhaps some sort of supernatural universal force; and that there is maybe (but maybe not) some kind of afterlife, or reincarnation system, or... who knows. But I meet precious few religious people who think like this; I guess most people who fall into this category would tick the "spiritual, but not affiliated with a religion" box.
