"Scientific evidence for God's existence is being claimed today by theists, many of whom carry respectable scientific or philosophical credentials. "He" who is neither a "she" nor an "it" supposedly answers prayers and otherwise dramatically affects the outcome of events. If these consequences are as significant as believers say, then the effects should be detectable in properly controlled experiments."
