I don’t think you understand atheism? As an atheist I do not believe in any form of deity or divine authority. I do not reject a specific religion, I do not actually believe there is any form of divine order to our world. I can look at faiths as the social constructs they are, and find interest in concepts humans have been developing and created cults around but there won’t ever be a religion/deity I will look at and somehow start to believe. And religious doctrines do not come for free, they are fundamentally built on top of a belief in a divine truth. My moral values may overlap with some religious people at a given time but we are using incompatible models to analyze our world
