Many of us in the scientific community have a longstanding policy not to debate with creationists, in part because doing so gives an unwarranted credibility to their disingenuous arguments. So when Bill Nye chose to debate Ken Ham in the Creation Museum on whether creationism was a viable explanation for life, there was a lot of wincing and predictions that Nye would unintentionally do damage to public perception of evolution. I was also skeptical that this debate would do any good. But I think that most of us scientists had overlooked the fact that Nye is an experienced entertainer as well as science educator–a combination of traits that most of us don’t possess, and one perfect for this venue. Nye did an astounding job at calmly explaining the overwhelming evidence for why creationism (with special attention to Noah’s ark and the flood) simply couldn’t explain the origins and diversity of life on earth. Ham, on the other hand, seemed really flustered and didn’t even make an attempt (beyond trotting out token creation scientists in an attempt to give creationism some legitimacy) to address the questions at hand with evidence. He was completely out of his league, and it showed.

One of the most telling parts of the debate was the question that was asked of both men: “What, if anything, would convince you to change your mind?”
Ham’s answer: “Nothing.”
Nye’s answer: “Evidence.”
I really encourage you to watch the entire debate here, but if you’re not up for three hours of viewing (and I don’t blame you), you can see shorter excerpts and an interview with Nye here.
And here are some other reactions to the debate:

Nye was right to do this debate. Not only did he win with excellent presentation and overwhelming evidence, he managed to convey to viewers the beauty and humility of the scientific process. Nye didn’t have any problem saying to some questions: “I don’t know–but I can’t wait to find out!!!”: the motivation that drives every single scientist when he or she goes to work in the morning. If nothing else but this gets conveyed to the people who watched the debate, I’d still be pretty happy. I don’t know if the people in the Creation auditorium had ever heard the evidence he presented before. (They seem to be proud of their lack of understanding of evolution). I doubt he changed any of their minds, but I can’t help but wonder if some of the people watching the stream went to bed last night with a slightly better understanding of the scientific process. I hope they did.
