Something that I've been thinking about is why God's policy on how much "proof" he gives people of his existence seems to have changed compared to back during the stories told in the Bible. Adam and Eve had NO reason to doubt God existed, they had conversations with him. Why doesn't God have conversations with anyone today? It'd be pretty hard to doubt His existence if he were anywhere near as chatty as he was back then. Or how about Jesus; he, allegedly, came back from the dead. Why the doesn't anyone else come back from the dead? That'd be pretty damn convincing. We don't even have to go that far, just show me some priest walking on water or turning water into wine. Then pretty much everyone would have damn good reasons to believe and we could stop fighting over that and get back to bickering over if masturbating will send us to hell and important topics like that.
Why did people back in the day get to see all of these miracles that are obvious proof of God, or at least a time traveling multi-class Cleric/Wizard, and we're left with "you just have to have faith"? Inevitably someone will replay with "it's all part of his plan," or some variation if it, which opens up a whole other can of worms. God, in his infinite wisdom, comes up with a "plan" that results in more and more people beginning to doubt His existence as they slowly discover how the very universe He Himself made works? Eventually it gets to the point where his "plan" has far shittier results than what he was doing way back when.
