It's good to hear a doctor say this. I have a degree in mechanical engineering, so I know enough to tell you that the complexity of the human musculo-skeletal system is countless orders of magnitude greater than any machine created by man.
How anyone can believe that such a complex creature arose by chance is beyond me.
It's simple: there is no way any self-respecting engineer would design anything as kludgy and as ineptly engineered as the human body, and then BRAG about it afterwards.
