(3) What kind of a role? The Bible clearly says that God created and sustains the universe. Science has now shown that God's creation is more marvelous than Darwin suspected. With no knowledge of the world of nanotechnology within living cells, Darwinians until recent decades saw living cells as somewhat like Lego blocks. Now we know that cells have complex circuits, sliding clamps, energy-generating turbines, rotors, stators, O-rings, U-joints, and drive shafts.
Here's what is key: Each little engine depends on the coordinated function of many protein parts and doesn't work unless all the parts are present. Could all those innovations arise sequentially, or would they all have to happen at once? That's the "irreducible complexity" biochemist Michael Behe wrote of in Darwin's Black Box. Francis Collins in his Socrates in the City (see "Mission to Metropolis," Feb. 14, 2009 [http://www.worldmag.com/articles/14951]) lecture pooh-poohed that notion, claiming that in the beginning God created the universe and programmed His creation so that everything would play out. It would be great for Collins and Intelligent Design theorists to debate—and perhaps find more in common than they think.
If "irreducible complexity" is proven, Darwinian materialism is dead. If it's not proven, materialists still have to find some way to account for the existence of human life and a universe congenial to it. They mutter about the role of chance mutations, but mutations are rarely advantageous, and it takes far greater faith to believe that you or I could arise by chance via millions of mutations than it does to believe in the Bible.
(4) Let's admit that the Darwinists are right about one thing: We're in a predicament. We don't ask to be born, but here we are. We normally don't want to die, but we do. Not knowing why we're here, we look for hope. Christians hope in God saving sinners, but evolutionists must have faith in other things unseen to be saved from a sense of meaninglessness.
Let's have compassion for Darwinists as they develop desperate theories positing the existence of an infinite number of universes. Many cloak themselves as objectively scientific, but that can't dodge even what secularists like novelist Kurt Vonnegut acknowledge: "My body and your body are miracles of design. Scientists are pretending they have the answer as to how we got this way when natural selection couldn't possibly have produced such machines."
