It's a deliberate attempt to try to muddy peoples' understanding of science in order to assert a religious and political view. The fact of the matter is that there are many fine degrees with which to study religion, God and creationism. And in a way, all of these degrees can rely on science in terms of how such studies are carried out. It would be hard to carry out any academic studies in any discipline and not follow a rigid method of investigation and conversation.
But what this bill and Intelligent design have in common is that they are less an assertion that Creationism is a valid theory, as defined by science, to be pursued by scientific method, but a way to undercut evolution. Intelligent Design was based on a (deliberate) misunderstanding of terms like 'laws' and 'theories'. The thinking was that since evolution was simply a 'theory' it meant that scientists weren't really sure and therefore it opened the door to other explanations of how life came about, one of those explanations being Creationism. Further, Intelligent Designers (is that the correct term?), tried to employ a very basic, flawed scientific method in order to 'prove' that one could carry out experiments that would support Creationism just as much as other experiments and evidence could support evolution.
All of was meant to play out in the popular realm, not the scientific community. Again, this was a deliberate attempt to confuse the public about how science functions in order to assert a specific viewpoint rather then trying insert Creationism into a serious, scientific dialog.
To me, this is dangerous. I think that many of these fundamentalist religious believers have political aims. They want to insert themselves into every aspect our lives and believe that that science, as they understand it, is a threat to their goals. They know that if they can have 'scientists' teaching their brand of religion - and let's be clear that this is a far more radical view of religion then most - to our kids, then those kids will grow into adults and be more open to their political/religious/moral/social beliefs.
