But what do we do if the core factual claims turn out to be false? Jesus didn’t rise from the dead, nothing happens after you die, there is no anthropomorphic super-entity like the biblical god or Allah from Islam, and so on.
If it this turns out to be the case, we can’t just pretend otherwise.
Can we make a better religion that doesn’t depend on false myths?
I don't believe that religion works if it is sold as a series of fables containing practical advice encouraging pro-social behavior (even if that's how it functions). Religion works as myths that are true and make your hair stand up when you read them.
Most Christians have already shed a lot of now-disproven beliefs. Angels aren't literally flying in the sky over our heads. Literal stories get re-interpreted as metaphors or the definitions of words changed. Contradictions get solved by picking whichever one agrees with the culture at the time. And there are a lot of contradictions, so if logic was enough to un-believe a Christian, they would all have become atheists already.
