What would prove GOD does/doesn't exists?
"god" revealing itself would prove it exists. if god is incapable of making itself known in a fashion that would be undeniable, perhaps "god" is the wrong name for this supposed entity.
I think that homo sapiens brains have evolved to an interesting but somewhat dangerous place, where we can conceive of questions whose answers we are not intelligent enough to fully fathom. So we make up lots of stories to fill in this void between what we can ask and what we can't yet know. We do this with myths and religions, and stories of gods. god is the spray foam we use to fill the gaps in our knowledge.
god made the sun revolve around the earth... until he didn't. god is magical thinking, necessary for many to avoid going insane at the precipice of all we don't know. if we can accept that the answers exist whether we know them or not, and then consider that our little brains may not be able to take it all in, then perhaps we can let go of needing to know. 40 years of asking the big questions, and that's what I came away with.
over and out.
