Craig Ventner (CEO of Celera genomics), a well-known atheist, was once asked if he believed that God created man (or some similarly loaded question -- I don't remember exactly) during a press conference. His response (to paraphrase): "It is obvious that no human could have created this."
It was a brilliant response. The religious crowd interpreted it as acknowledging the hand of God in our creation. The people who know something about genomics knew that he was referring to the fact that the human genome is a barely functional piece of crap that would be an egregious failure if it had been designed by human engineers. The fact is, normal human engineering practices would never allow such fundamentally flawed design to leave the drawing board. This is a VERY cogent question with respect to the intelligent design hypothesis, as there is a ton of evidence even at our relatively primitive level of genomics capability that if humans were designed, the engineering was far worse than what you would normally expect out of a human engineering team, never mind God.
As I'm sitting here typing, I would never conclude that the human genome is a barely functional piece of crap. Rather, Ventner is intimately aware of the complexity of the human genome and all that goes with it. In his own famous words: "We don't know sh!t about biology."
