Stephen Colbert interviews atheistic Darwinian Richard Dawkins. It's pretty funny. Along the way Dawkins impresses the audience with the question, "If God designed the world then what designed God". Despite the audience's enthusiasm for the retort it's really little more than a red herring. The answer, of course, is 1) nothing, and 2) it doesn't matter.
1) The universe is the totality of all contingent (or designed) things and therefore the creative cause of the universe cannot itself be contingent or else it'd be part of the universe.
2) Once it is agreed that the universe has a creative cause, as is tacitly done in Dawkins' question, the argument is over. In order to pose his question Dawkins has to tacitly accede to the theist's main point which is that the universe has a cause responsible for all of its order, design, and personality. Whether that cause is itself caused by something greater than itself makes no difference to the argument that the universe has a cause outside of itself and does not alter the fact that the theist has won the point.
