Richard Carrier argues that if the Christian God were indisputably clear, instead of silent, about what he wants from us, and if he were to leave for us the kind of evidence that would lead us to virtual agreement on who he is and what he wants, then Christians would have a more persuasive argument on God’s existence:
Instead, we observe exactly the opposite: unresolvable disagreement and confusion. That is clearly a failed prediction. A failed prediction means a false theory. Therefore, Christianity is false … Truth is not invented. It can only be discovered. Otherwise, Christianity is just a hypothesis that has yet to find sufficient confirmation in actual evidence. And no such hypothesis should be believed in, until that required evidence appears.
