I heard an opinion says that god is something the governor invented to guarantee their dominance. They will tell people it god's idea when they want to release some new policy. People who believe god will follow the politics without hesitate. Review the history we can also found that the governor in middle ages are always the churches or the kings control by church. So I always believe god is just a heritage of that age. In modern age it's more of a spirit for people who believe it.
