The guy is basically saying, "The universe is too complicated. There must be a God."
But that's a cop-out. Humans have been apt for a very long time to say, "I don't understand it. Therefore, God must have done it."
If there is lack of convincing evidence regarding the way the universe came to be, it is important to recognize that that fact, in itself, can become proof of nothing else. To illustrate how lack of information never can become positive proof, consider the following two sentences:
No one knows how much money Joe has. Therefore, Joe is poor.
Obviously, the conclusion is a non sequiter. The fact is that we have no information regarding Joe's financial status. The only conclusion we can draw from this is that we had need to get some better facts if we want to have anything to say on the subject.
When a person, "We don't know how something as complex [/beautiful/awesome/sexy/etc] as the universe could possibly have come to exist without an intelligent creator," that conclusion does not become proof of a creator at all. It only becomes proof of the ignorance of the speaker.
