> If religious belief systems are "wrong" (in the sense of being useful for navigating the world, not in the sense of satisfying certain conditions of symbolic logic and reasoning), then why have these religions triumphed over secularism time and time again?
To be fair, a lot of them spread by the sword. Convert or we kill your tribe. Some of them explicitly call out in their texts that it's OK to forcibly convert or murder non-believers, an attribute which is, I'm sure, a helpful "evolutionary gene" for the religion's spread. There are also religions with non-violent, but still coercive conversion, where there are non-death-related social consequences for nonbelievers.
