First of all, I'm getting really tired of this statement that "Intelligent Design" assumes that there is a God. Now I know that's what most folks who share my belief in God want you to think. Unfortunately, in addition to being a Christian, I'm also well-versed in science. And science and Christianity are not incompatible - provided that BOTH keep open minds. I doubt that some of the (other) fundamentalists intend this, but if they want to play in the ballpark of science, they have to play by scientific rules.
Intelligent design means just what it says: that the development of life on earth was planned at some level - whether natural or "supernatural."
In other words, if an alien race seeded the earth with organic material or lifeforms, that would constitute "intelligent design" the same way which an all-powerful God creating life would. BOTH are "intelligent design."
The real problem with "Intelligent Design" is that it is exposing the fact that scientists aren't nearly as open-minded as they want you to think that they are.
Let me give you a scenario - whether it is actually the case or not is unimportant. The premise of science is that it leads us to knowledge, understanding, and "TRUTH." Therefore, to accomplish its goals, science *MUST* cover every circumstance.
Pretend that life was "created" by a supernatural force - by God.
In order for science to arrive at the truth, it MUST end up with the conclusion that God exists. Obviously, in order for science to arrive at that conclusion, they'll have to either a) theorize that God exists - in other words, make a "best guess" - or B) prove that God exists.
In order for science to arrive at the truth, they must be open to the POSSIBILITY that God exists. Ditto with aliens. Ditto with the forces of randomness and chance.
Any scientist who does not leave their mind open to the possibility that God exists (until conclusively proven that God does NOT exist) is not practicing good science - he's practicing RELIGION, where faith alone is good enough. In this manner, he is violating the scientific method. And I do not advocate teaching this type of science in anything other than in a religious institution.
As you can guess, I'm in favor of teaching what few "facts" are proven about "Intelligent Design" - which, to my knowledge, is none. Until then, only the questions posed by "Intelligent Design" are necessary to be taught - QUESTIONS are *ALWAYS* supposed to be taught when dealing with THEORIES. At this point, "Intelligent Design" should be referred to as a HYPOTHESIS. Likewise, Evolution should be referred to as a THEORY (a hypothesis supported by scientific evidence). Scientifically speaking, that's what each is. And I believe that for true knowledge, we need people investigating - via the scientific method - the HYPOTHESIS of Intelligent Design.
The method I propose - the pure scientific method - will eventually lead to the truth - whether life was created by God, by Evolution, or by a Flying Spaghetti Monster. Neither religious nor scientific fanatics can say the same about their methods.
Sorry, but when I see "Intelligent Design" being attributed only to "God" *OR* when I see hypotheses being dismissed without cause, I get a bit upset. Science prides itself on precision and accuracy. Semantics matter. (Call it the engineer in me, I guess.)
