Couple things. Well, 4 really.
1. When you first hear it - why won't god heal amputees? - you think, what the heck? But after studying the web site questions, you will realize the idea comes from the ambiguity of prayer. As a proof of the possibility that no god exists, comparing the answered healing prayer of, say, a cancer patient, to the answered prayer of an amputee is a way to remove ambiguity. Understand?
2. I hear the view that there are more pressing things than this debate. But when you think of the effect worldwide of extreme Islamic views, or Hobby Lobby vs. government health care, or the ideas affecting how science should be in U.S. schools, or in fact whether it is right to teach women in any school, as some Islamic views dictate, or how many countries treat their aboriginal peoples based on someone's perceptions of correct beliefs and customs, doesn't this debate cut to the heart of most important world issues?
3. There is also the simple idea of truth, and the pure debate of what the truth is, and realizing the importance of discovering it.
