while at face value i agree that it's a false dichotomy, i don't think you appreciated the degree to which this devalues creationism:
unlike agnostics, for which the mere possibility of god coinciding with current scientific paradigms might suffice, for creationism there is a deep seeded belief that in order to explain the splendor, diversity, complexity and seeming order emerging out of the chaos, which defines life as we know it, as well as it's very existence, god is not merely a side dish, but a major requirement, that a miracle is required to explain all of this.
evolution comes in, the miracle is pushed to the laws of nature
DNA chemistry comes in, the miracle is pushed to biogenesis
the RNA world comes in, the miracle is pushed to the still mysterious emergent of cellular membranes
eventually that will probably be recreated in a lab as well... the miracle would be pushed to the primordial soup.
solar system evolution is already starting to comes in into planetary levels, and the miracle is pushed to the big bang.
now out of quantum physics, the multiverse is testing the waters, which means that the required universe to support life conditions isn't a miracle, it's just an unavoidable result of every physically possible universe existing, and we just happens to be in one of those things with life in them, because where else could we emerge in the first place?
god can coincide on an agnostic level, as a possibility, but the deeper and more through the understanding goes, the less he seems to be needed.
i think believers are NOT a bunch of idiots incapable of healthy self doubt and reason, they include the same vast diversity of levels of intelligence as the rest of the human species, do in fact ask themselves why they believe... and natural science, well, its stripping them of their best answers, and quite a few of the older generations might fear for their children's faith. this might seem irrelevant to an agnostic PoV, after all they should accept their children no matter what, right? but if for a moment you consider a religious parent's PoV, a belief that your children will actually suffer and experience an infinity of torment for not believing, would you want to save your child from that at all cost? for those and probably many other reasons, scientific theories devaluing the role of the miracle pose both a personal and a sociological threat.
it is ironic, that simply believing you believe because it depicts the universe in a more meaningful way to you, is in itself not a very meaningful enough belief for most.
