God seems to value faith- or- we're lead to believe that they do. That's either a convenient 'get- out' clause for the religious folk- they don't need to prove anything. But- if it's true, then the less physical evidence, the better- because that is the test of true faith I suppose.
Not sure why God would need to play these weird elaborate games. Their character always seemed terribly narcissistic and sadistic to me though. They demand to be worshiped. Yet, they deliberately make it so that we will seriously question whether they even exist. They make it so that there's no concrete proof that they do even exist. Then- if they are in fact real, they get to punish all the unbelievers.
So- I'd say- either you're right- and hopefully you are. Either the lack of evidence is because there is no God. Or, there is and they're toying with us. Or, there's some deeply good reason everything is the way it is- that we are too limited to comprehend.
