I don’t think Religion created our problems, I think we did. I think Religion is just our brains trying to maintain sanity. We can’t fathom “infinity”, we can’t fathom the times before or after our deaths. I think religion was just created by people who need to attribute something to that, so they can get their minds off of it.
It has been used as a weapon, for sure, but I don’t think there’s any getting rid of it. I think naturally we gravitate towards it due to our need to understand the world around us. When we get to something we can’t wrap our heads around - it’s easy to just explain it away with a story. Others will dive even deeper into understanding it (science and the scientific method)
