Do you not see how those statements contradict each other? You say, on one hand that intelligent cannot preclude intelligent design and, on the other hand, since it can't it isn't "science" and should hold be withheld from any discussion. It seems to me that in the 3rd century the fact that the earth could not be shown to be round, your reasoning would have precluded any speculation that it may be true.
Aristotle had three proofs that the Earth was round and Erastothene sometime later actually measured the size; the Earth's shape was known before this even. Perhaps 600 years later, people had forgotten this. (Or maybe you left of the BC.)
should hold be withheld from any discussionNo, I'm in favor of it being discussed, but I don't think that a science class is the correct forum for a non-scienctific subject. Students would get pretty confused if their english teacher suddenly started teaching them maths, right?
God can do anything. Therefore, He could have designed living systems that Evolve. Yet finding life that Evolves, does not show that there is an Intellegent Designer.
You really can't quantify or measure anything that can be done by God. litterally any result can be explained by the magic words, "God did it".
Question: Does God manhandle the earth around the sun, or did He design Gravity and let it do the rest? How would we be able to determine the difference? Be specific. Describe an experiment that will tell me the answer to that question.
