Yes. They bled him to death. Current medical uses of leeches are different...and based on science...unlike faith-based ID.
I am not an IDer, but...Can you demonstrate, via existing evidence, and without any faith (or assumed conclusions, which is a demonstration of faith), the Darwinian evolutionary claim of the simplest single cell organism (the point in time right after abiogenesis ends in the primordial soup) evolving into the diversity of life that we observe today?
And, scientifically speaking, how can you (or anyone else) judge the correctness, or validity, of faith-based claims (if ID is faith-based...Is it any more faith-based than Dr. Crick's Directed Panspermia "theory"?) when "science" can not, or does not, address issues related to the supernatural?
Isn't the claim that there is no supernatural unscientific in itself?
