As a religious person how do you reconcile the mutually exclusive nature of most cosmologies and ideologies?

I've always been very skeptical of religion because either you think you're correct and everybody else is wrong, or alternatively everybody is wrong and stupid because we all live in parallel, (in some sense) mutually exclusive realities defined by our belief structures.

Personally, I want to live in the same world as everybody else. I don't want some arbitrary divider sectioning me off from the rest of mankind.

Edit:

"We're not like you." What?

If you're in a room with a dead body (Earth) and five other men and everybody believes somebody else was the killer (different creation stories I.e. how we got here) you can't all be right. Similarly I don't think everyone believes there are 5,000 different heavens each with a specific way in. If there is then that's a specific cosmology, distinct from the others.

TLDR People have different views on where the soul goes. We cannot be reincarnated, eternity in heaven/hell, Elysium, rejoined with our ancestors, etc. Simultaneously.

Since they cannot all be true would you not question yourself? If all such beliefs had an equal chance of being true then that puts you 1/1000 if you're lucky.

Whatever is going to happen is going to happen anyway. The only question is how do you live?
