DAVID: Just look at this entry to see the diagrams of the citric (Krebs) cycle which I was taught in med school, to see why a designer is needed:

QUOTE: I think we should make an attempt to explain to students that humans are the end products of three billion years of evolution and they have adapted to a specialized way of life that relies on ingesting and metabolizing complex organic chemicals. The pathways that we see as "normal" in humans humans reflect this specialization.

I accept the logic of belief in a designer, just as I accept the logic of disbelief in some unknown, unknowable, eternal, infinite, immaterial, sourceless, all-powerful, all-knowing conscious mind. That is why I am left with my agnostic non-belief. As regards the above, I think it is also worth explaining to students that there are lots of organisms that are the end products of three billion years of evolution and have adapted to a specialized way of life that relies on ingesting complex organic chemicals, and there are even organisms that have survived 3.8 billion years by adapting to a vast range of specialized ways of life, each of which relies on ingesting complex organic and even inorganic chemicals.
