In tonight’s debate between Bill Nye and Ken Ham, the Science Guy went on stage equipped with the most vital tool of all in any oral debate over evolution and creationism: a showman's flair, developed over three decades of experience explaining science to the broad public.

Of course, he also had the science on his side, which doesn't hurt. But it isn’t a guarantee of anything in a stage debate: competitive debaters are judged by their ability to argue either side of a question. Debate is a tool for showing who's a better orator, not necessarily who's right.
