So what happens to imperfect self-replicators if there is a god and if there isn't one? I'd say for such a scenario the existence of a god is not important.
I wasn't referring to "imperfect self-replicators." I was referring to people. Did you mean people by "imperfect self replicators?"
God's existence and the existence of our souls is the most important matter about which every person must come to a conclusion. For if God exist -- and He does -- we must seek to live our lives in the specific manner that He demands of us. If we come to conclude that He doesn't exist, we make up our own rules. As Stalin did.
To say that the choice in how we live our lives -- whom we serve so to speak -- doesn't matter, is pretty stupid.
