Religion without God?
Perhaps the first thing that may come to mind is Buddhism. There probably are other sects of religions (much smaller ones) where worship is either given to an animal, a spirit realm, or even the Earth or Sky. Maybe even the Sun. Perhaps these people are rational enough to not believe in God, but still believe can treat something like a God. To me buddhists build statues of Buddha here and there, and their teachings in a way are somewhat religious, even if they don't pray to a god.
Do you think these people are better than religious people who do believe in God? Perhaps better? Maybe worse? Or as equally as irrational?
