I agree with Thorne that the miracles of our forebearers can be almost entirely explained through scientific inquiry. As Arthur Clarke wrote: "Any sufficiently advanced technology is indistinguishable from magic."

Knowing why a rainbow happens does not lessen its beauty. In fact, I think knowing the enormous odds of not only our planet developing in such a way to sustain life but the fact that you (individual) exist, is pretty darn miraculous. Is it the hand of G*d? In my opinion, it doesn't matter. I'm just thankful to have people like you in my life.
