It’s really simple.
There have been hundreds, probably thousands of god stories in different parts of the world and different historical periods. There was the endlessly squabbling unhappy family of Greek gods. There was Ra and his half human, half animal friends in the Egyptian pantheon. There were the deeply sinister Aztec gods. There’s God / Yahweh / Allah originating in the Middle East. The Romans seemingly had a god for every conceivable purpose. Hindus have gods, goddesses, divas and avatars by the hundreds, if not thousands. And that’s just a sample to illustrate my point.
These stories can’t all be true. Some of them – most of them – must be false. Indeed, the myths themselves often include warnings against “false gods”. The Book of Exodus describes how the Israelites invented a false god (a golden calf) for themselves, in a matter of days, when Moses was up Mount Sinai communing with (the real) God.
These diverse and imaginative god stories illustrate just how good humans are at inventing myths, and what a deep need we have to create them. And if that’s true, then doesn’t it seem very likely that they’re all invented? Why would your god story be true and all the others false?
When civilizations end, their gods die with them. No one still believes in Zeus, or Thor, or Anubis, except as stories. Gods and religions are cultural artifacts – nothing more.
What I really don’t understand is why most other people don’t seem to see this.
