"intelligent design" is not scientific,and definitely NOT a theory. Its a philosophical construct at best, and belongs in a philosophy class.
As a Creationist, I happen to agree with you 100%.
Creation Science is built around the idea that if you start with the Bible as the source of your hypotheses, you should be able to find scientific evidence that is consistent with those hypotheses. If the evidence instead contradicts your hypothesis, then either your evidence is flawed, your interpretation of the evidence is flawed, or your interpretation of the Bible is flawed.
Intelligent Design, in contrast, does not start from the premise that the Bible is a literal historical document, because that would mean religion is involved. Instead, ID simply says that life is too complex to have evolved spontaneously on its own, therefore God must have done it. On the surface this sounds similar to Creation Science (both say God did it), but ID doesn't bring anything falsifiable to the table.
The question of whether or not God (or the FSM or space aliens) caused a particular event is not testable empirically, even if it is true. Creation Science doesn't try to test God's involvement, only the actual physical events described in the Bible (for example, that there was a global Flood around 2,000 BC or so that wiped out all humans and animals that couldn't fit in a really big boat). It doesn't look at whether the events described in Genesis were really caused by God, only whether or not they occurred as described (and the mechanics behind how they occurred).
