I would suggest that one's view of our origins don't [sic] have any practical effect on any subject - not medicine, engineering, biology, etc.
You are demonstrably wrong in this suggestion, at least as to biology and medicine. And, if you include in "view of origins" the idea of a world wide flood at any time in the past, you are also demonstrably wrong about engineering. Belief in biblical creationism and a world wide flood contradicts fundamental principles in each of the fields you mention, and many others as well. As one example, consider geology. Take the example of Glenn Morton. Coming out of college, he was a committed creationist. However, as he began to do actual work in the field, he discovered that the evidence was inconsistent with what he was taught. He struggled for years trying to reconcile what he could see with his own eyes and the drivel that he'd filled his head with about a young earth and the noachian flood. He finally came to the conclusion that what he had been taught about a young earth was nonsense. You can read his story
here.
Now, I suppose that it's possible to do some selected work in each of those fields that, as a practical matter would not be affected by belief in creationism or the noachian flood, but that is not nearly the same as saying that those beliefs wouldn't have any practical effect.
