Not because of evidence, since Nye brought up material that had been dealt with long ago by creationists and he would have known that if he had bothered to do his homework. Not because of logic, because Ken Ham was straightforward about his worldview and reasoned properly, and Bill Nye used numerous logical fallacies. Not because of demeanor, Ham was gracious throughout and Nye was basically civil (although demeaning and contemptuous). But the main problem was the format for the debate, and the fact that the title of it was putting Ham on the defensive: "Is creation a viable model of origins in today's modern scientific era?" How about, "Defending evolution despite modern science" for Nye?
This has been a hot time for creation science. At the end of 2013, a Pew poll showed that atheistic evolution had not gained as much ground as the atheists would like. There is a movie in the works about the real Noah, not the Hollyweird version. Creation Sunday is countering Zimmerman's call to apostasy with his misleading "Clergy Letter Project". Question Evolution Day is February 12. So people are really checking out the truth of creation science, and not just what they've been told to think by atheopath sites and evolutionist propaganda mills.
After this video, there is a song I'm dedicating to Bill Nye, by the 77s.
