I've always thought that the biggest difference between religious people and atheists is that we're willing to just say "I don't know".
I don't know if there was something before the universe, how it'll end or if there will be something after, or if we're in some kind of simulation, or whatever else. But I'm willing to leave it at that and I don't feel the need to point to some deity to fill in the gaps of my knowledge.
I've never understood why people so often keep the two separated. Like, if you already believe in a god, why not interpret things like physics and chemistry as how your god set the world up to run? I totally get that religion is complex and divisive, but at an individual level, it seems like such an easy "problem" to resolve.
