Whether one speaks of self-organizing principles in living things or of processes of emergence, the conclusion often reached is that nature is self-sufficient. A creator is irrelevant at best, so the argument goes. Theories in contemporary cosmology have been used both to affirm and to deny the existence of a creator.
