What I'm saying is that your main argument is non-scientific. Who is correct concerning the ultimate "whys" of creation actually doesn't matter in science. Does everyone who benefits from Newton's Principia Mathematica agree with him on theology—which, according to Newton, was the foundation of his work? Undoubtedly not. Is everyone who loves Bach—who dedicated every on of his works "To the glory of God"—a 17th-century, high-Church Lutheran like him? No.
The alarm over the Intelligent Design folks seems to me to arise from historical ignorance. People always have had their own reasons for doing their art or formulating their hypotheses. I also seem to detect a special alarm by liberals and libertarians about the ID folks, as opposed to the creationists, perhaps because the ID scholars have real degrees and no Southern accents that are easy for city-folks to dismiss as ignorant. Michael Behe, for example, speaks very well and writes very compellingly, following the rules of reasoning at least as carefully as Richard Dawkins.
It won't be proved in high school class whether God created man or flatworms did. As long as the kids do their experiments and write their papers by the rules and procedures of science (invented by believers in God, by the way), drawing their inferences according to logic, who cares whether the teacher tells them Darwin had it wrong? The practice of science, not the theology, is what counts.
‘Who is correct concerning the ultimate “whys” of creation actually doesn’t matter in science.’
True, but I did think of one other interesting issue this morning.
ID is frequently conflated with Christian theology. If one ignores (for the moment) Christianity, but posits ID, there is quite a pause between the creation of the Universe 13.7 billion years ago and the creation of life approximately 2 billion years ago (not to mention another big gap until potential worshipers a few million years ago). Cosmology, geology and paleontology all point to that timeline being generally correct.
So, if the Creator and the Designer were the same, what was it doing for the 10.3 billion years in between?
