I think the value add of religion per the top comment is that it typically has a built in community and sense of connection. Churches bring people together in multiple ways.

I write that as an atheist who is more isolated than I'd like. I'm working on community and connection but it's challenging when one works remotely and relocates to a new town.

While I recognize the community value of religion and the comfort it brings people, it comes at a huge cost that far outweighs the benefits. IMHO, organized religion is a cancer on modern society. I think there's other ways to get the good parts from it but that's a team effort.
