The notion that we must choose a constructed belief system, an archism, in order for the world to survive or to live a practical life, is for children. You learn this stuff in school, are shown the list of accepted dogmas, told that mature people choose one of them, and are given the assignment to morally affiliate. In addition to not believing the dogmas, I don’t believe affiliation will save us, or that you are more of a reasonable adult because you are a believer.
