You seem awfully ignorant. Read some of Einstein's writings for instance. There are many famous, respected scientists who are deeply religious. However, science by definition does not address "God" or the "supernatural", at least as long as they are claimed to have traits and capabilities that transcend the physical world.
Science has not made, nor does it seem likely to make, any pronouncements about what existed before the Big Bang, or what caused the Universe to have its particular laws and composition. So, the explanations that "God created the Universe", "the Universe suddenly appeared randomly from nowhere", and "the Universe was created when an extra-universal garbage collector accidentally collected too much garbage and it imploded" are all equally plausible and likely from a strictly scientific standpoint. Science is willing to concede that the unknowable is the province of religion...it seems to be taking quite some time for religion to admit the counterpoint, that the knowable is the province of science.
I think ID should only be taught in science class if Flying Spaghetti Monsterism is given equal time, and the reason why is fully explained.
Heathen infidel blasphemer! Everybody knows the Invisible Pink Unicorn (PBUHH) created the universe. Reject your pagan pasta god or be cleaning out Her stables for eternity!
Atheistic science by definition does not investigate such things, yet it seems to do fairly well. You make the mistake of protracting your preferred definition of science into a universal definition of science. It is well within reason to assume science is simply the exploration of everything supernatural while it merely assigns the words "natural" to those things for which it has an explanation. One thing for sure: there is no lack of organized matter behaving under predictable laws. That is what intelligent design is all about.
Maybe your definition of "scientists" extends only as far as those who wear lab coats and propose detailed hypotheses for specific phenomena. Mine is wide enough to accomodate any intelligent observer who is free to accept or reject any positive statement about the universe based on the evidence at hand. Since the universe is replete with organized matter that behaves according to predictable laws it is hardly unscientific for an observer to deduce that an almighty, intelligent agent is present and operative.
