Yes, the explosive diversification of life on this planet was an unpredictable process. But so were the rise of Western civilization, the collapse of the Roman Empire, and the winning number in last night’s lottery. We do not regard the indeterminate nature of any of these events in human history as antithetical to the existence of a Creator; why should we regard similar events in natural history any differently? There is, I would submit, no reason at all. If we can view the contingent events in the families that produced our individual lives as consistent with a Creator, then certainly we can do the same for the chain of circumstances that produced our species.
