So there is no way for something to prove it is a god?
I think that's right. Through mankind's history, the gods or divine beings that have tended to 'survive' are the ones whose existence is an article of pure faith. I think part of why the Abrahamic religions supplanted so many of the ancient religions is because so many of the ancient religions were efforts to understand natural phenomena and didn't stand up to scrutiny. It's the metaphor of Saint Patrick driving the snakes out of Ireland: As humanity's rational understanding of the natural world grew, we no longer needed the supernatural explanations*. Nobody could believe in Quetzalcoatl today, even if they wanted to, because Quetzalcoatl was supposed to be the god of wind and rain, and to manifest as a snake (a
winged snake, at that). I think the Abrahamic religions flourished in part because they don't even try to provide a rational explanation, they just tell us to believe. People who genuinely believe in God don't really need evidence, in the scientific sense. People who believe in God might point to natural phenomena - the beauty of a sunset or the joy we feel from a baby's laughter - as 'evidence' of the divine, but that's an interpretation that rests on the faith they already had. It's the circular reasoning that I mentioned earlier. Or they might point to something that science hasn't explained yet, but that doesn't fly either, because of humanity's history of explaining things we previously thought were supernatural or divine. I think when a person of faith tries to show the agnostic person their 'evidence', that's them trying to reach out to us and speak to us in a language they hope we might understand. They don't actually need evidence. Heck, even asking for evidence kind of betrays a weakening faith, doesn't it? Some people of faith even think their faith is all the stronger if it flies in the face of the evidence, as though that's some kind of strength of character, or commitment, or something. I realize I'm reaching here, but the fact is I really don't understand it. I can only try to grasp the fringe loonies by understanding them as political entities knowingly preying on people - the Taliban - or as individuals with mental illnesses - Jim Jones (although most cult leaders are also predators taking advantage of people for their own, nonspiritual ends - Keith Raniere has been in the news lately - in addition to being people with troubled minds of their own).
* The story of St. Patrick driving the snakes out of Ireland had to be some kind of parable
even at the time, because people from other parts of Europe had already seen that there were no snakes in Ireland, hundreds of years before he was even born. So that legend was
never true, in
any way
, and could only ever have been thought to be true by people who already believed in the divinity of saints and rejected (or were ignorant of) the documented observations of the people who came before them.
