Watching the debate on YouTube. Each side just finished their first arguments.
First, the debate topic is too broad, and it allows too much from both sides to be brought in which can't be discussed in depth. The debate topic should have been something like, Is radiometric dating a reliable gauge of the age of rocks?
But because the topic is broad, the floodgates are open to allusions to a dizzying array of subjects the education of which most have only an introduction, and that frought with mistaken notions.
But despite that, Ken Ham was well-poised, well-prepared and within his first five-minute presentation identified the need to define the terms in the question and to be consistent in their usage.
Bill Nye seemed nervous, and seemed to be winging some of his arguments, and that surprised me, but I think his weakness could have been due in part to the fact that he didn't expect Ham's opening to be a strong one, and that he himself didn't realize till that night that he employed shifting definitions in his arguments. I could be wrong. I got the impression he was expecting a featherweight and got suckerpunched.
That's my impression so far.
