Quote by D.A. Carson

“irreducible complexity,” that is, structures in nature and in the human being that are so complex that it is statistically impossible that they could have come to be by chance. To appeal to a chance mutation, or to the mere selection of the fittest, or to any of the other appeals on offer in the various heritages that spring from Darwinism, simply makes no sense. Living systems have an irreducible complexity to them that makes it statistically impossible that all of the necessary but highly improbable steps were taken at the same time—and without such statistically impossible simultaneity, life could not be. What this suggests, it is argued, is the need for a designer.”
