No, I think it's more a matter of A. our endless curiosity for things we do not understand and trying to make up or find answers for them and B. our very inventive ways to control people in our greedy hunger for power.

I don't believe in mankind if that's what you think, I believe in goodness though, but I wouldn't call that a power, but a choice instead. Why would we (have to) worship things like greediness and power when we do not believe in God? It's not like we're totally immoral emotionless life-hating freaks, we only do not share your believe of a higher power as a being called 'God'. I understand it's difficult to understand a world view without God though, it's a big difference with all kinds of consequences. (like for example what purpose has our life if it's not for God etc. ..)

Cheers
