OMG, that was painful. Bill Nye began by wasting two of his five minutes of opening statement talking about freakin' bow ties!<p>Then the first substantive statement out of his mouth was: the question tonight is, does Ken Ham's creation story hold up? Is it viable?<p>No no no! The question is: what is science? And the answer is, as the late great Richard Feynman put it, science is the proposition that EXPERIMENT is the ultimate arbiter of truth. So as soon as you say, as Ken Ham does, that the Bible is the ultimate arbiter of truth, you are not doing science BY DEFINITION.<p>Now, Ken Ham contends that secularists have "hijacked" the word "science." No. It is Ken Ham who has hijacked the word, because the definition is not arbitrary. There is a REASON for it. That reason is, as Ken Ham himself admitted, it works. Experimental science has produced all of the world's technological progress.<p>When Ken Ham claims that the central tenet of science -- that experiment is the ultimate arbiter of truth -- cannot be applied to the past because "we weren't there" he is simply, demonstrably wrong. It can be, and it is.<p>Now, of course one can choose, as Ken Ham does, not to accept the premise that experiment is the ultimate arbiter of truth. There are certainly areas of human endeavor where that standard is not applicable: art, poetry, music. But it can certainly be applied to the past.<p>The debate should not be about whether Ken Ham's model of the world is "viable", the debate should be about what is the standard by which truth is decided: experiment, or a holy text. You can choose one or the other, but experiment produces better results.
