well, it's a concept, so i guess there must be God and Anti-God, and one is the creator, and loves and cares about life, and the other slays and decays and disorders everything.

as a living thing, i see no sense in worshiping or obeying a principle that literally is death

Christians usually make a distinction about God the Creator, and implicitly, as you point out, that means He is not everything, but it doesn't change the fact that everything else that isn't Him is worthless
