When one resorts to ad hominem attacks, one automatically loses the argument and the respect of any rational person. Faith attempts (and fails) to make sense of the unknown but faith is not a tool of knowledge. However, the scientific method is indeed a tool of knowledge. I personally don't see any difference at all in a five-year-old child's faith in Santa Claus and an adult's faith in God. What makes one faith-based concept better than any other?
