The "death of God" idea is an ironic one from Nietzsche. It refers not to the literal death or absconding of a deity, but to the growing irrelevance of religion to secular society. Religion has been the foundation of morality for most civilizations, so that leaves modern people with the problem of how to ground secularism to avoid mass despair, crime, and chaos. Nietzsche's solution was that new myths would emerge to inspire a posthuman value system.
But you see, now we're thinking about religion, which you said you can't be bothered to do.
