If you think the Koran is true,
then do what real scientists do:
Observe and then test.
Don't just make a guess,
don't count on what your "prophet" knew.
PZ tells a story about Islamic "science", in which the words of the Prophet Muhammad are subject to the scientific method. The issue, however, is that if you were to use shoddy science, you could prove anything, from a fly being dipped twice in a drink curing the diseases it carries to the existence of extra-terrestrials building the Egyptian pyramids.
