All Beliefs are Welcome Here!
Humans constructed their mythos; how did that even get started? Did someone just make up the concept? I don't think so. Humans once saw the Gods daily. They didn't rely on faith, they knew who the Gods were and the Gods left. The early humans may not have understood what was going on but they knew the Gods. They weren't some invisible old man in the sky who looks like Charleton Heston, they had airplanes and helicopters and flew around and built things.
The Gods are real, they are flesh and blood and bone entities. Perhaps one day they will return, which may or may not be a good thing for us.
