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.
Science's answers to the ultimate mysteries of existence are almost as baffling and logic-defying as the mumbo-jumbo of churches. They can seem nearly as absurd as the miracle claims of religion. But there's a crucial difference: science is honest. Nothing is accepted on blind faith. Every claim is challenged, tested, double-tested, and triple-tested until it fails or survives. New evidence often alters former conclusions. Honest thinkers have little choice but to trust science as the only reliable search for believable answers.
