That's the general feeling of most people on the side of science, don't give these loonies the credibility of a serious debate. From what I've read Nye was challenged because of this video and other recent criticisms of teaching creationism to kids-

This was the reply video from Ham-

He has the audacity to claim Bill Nye wants to indoctrinate kids and prevent them from thinking critically. This is the guy who runs a museum with this in it-
I think Nye is doing this mainly because his character has been attacked. Ham takes personal shots at him in reply to a video where Nye is reasonable and speaking in general terms. So in other words, it's personal.
Btw it's pretty telling that all the pro creationist videos linked to this story have their comments and ratings disabled while the other side leaves them wide open. Creationists are very hypocritical and fragile. They constantly try to filter reality. I hope Bill destroys him tonight he's certainly got it coming.
