Does God exist? Perhaps, if you mean something metaphorical by "God," you might be able to honestly answer in the affirmative. Otherwise, the most we can say is "I don't know." But honest people can go farther and say that the existence of unseen spirits is unlikely. When you get down to it, the only evidence of God's existence is that holy men, past and present, say he exists. But if their assertions about God are as valid as their assertions about witches, their trillion-dollar empires rest on fantasy.
