Navigating life in the Bible Belt as a non-believer is pretty much the same as being a progressive liberal. It's always fun when people find out and are shocked I'm not trying to destroy America, turn my kids trans, and start a war on Christmas. Bit of hyperbole, but no one ever treats me the same or acts the same around me when they find out.
After being immersed in it growing up and through early adulthood, it all just seemed liked people trying to attach a meaning to life and death that didn't exist and didn't need to. We are just another species living out their blip in time. We crawled out of the water, decided to go to the trees instead of back into it with some other mammals, then came down from the trees when we got smart. We are the lucky species with the most developed brains which has allowed us to think and build amazing things as well as develop complex emotions. The gift the universe gives us is that time is running out on your clock from day one, and we have developed the brain power to give that brief moment meaning. We don't need to invent a higher power to do it for us. But yeah, we live we die. Bad stuff and good stuff happens. Moving on.
Outside looking in, the one great irony I see right now is that we are the only species that has ever lived that can actually do the first thing we are told to do in the Bible, which is take care of the garden, and we are doing a pretty miserable job of it.
