Is it even possible to have empirical evidence for God's existence? What if the stars realigned to spell out "I exist! Sincerely, God." Wouldn't THAT count as evidence for God? It seems that the answer is yes. But then, various objections to arguments for God seem to imply that even this extravagant, awesome evidence for God would not be any evidence whatsoever for theism. To many philosophers, that implication implies that these objections prove too much, and must therefore fail. In this debate, eight philosophers go head-to-head over these fascinating questions.
