No that was Karl Marx... Nietzsche said that "God is dead and we killed him." There's a God, but don't confuse Him with religion. God created man; man created religion (for his own benefit).

The soul, or spirit, or life force, or essence- whatever the proper term is is indeed eternal. But is doesn't pass along any vertical scale... for example, if you're bad you come back as an insect. Once a human, always a human (or something similar) Maybe we go to another planet, the universe is a mighty big place.

There is a force (God for lack of a better term) that created everything using the laws of physics. This is also a moral force. It is NOT a religious force. I can't explain God because I can't understand God... we're not meant to and we don't need to. You should read my essay Gang Bang vs Big Bang.
