I think I have heard you make this claim of confusion before, but I am not sure who, in your view, has been confusing “design” with “creation”.
“Creation” in the Bible and Christian theology implies design (i.e., God knows in advance exactly what he wants to produce, what its properties will be, etc.), but the word denotes more than design; it denotes bringing something into existence, not merely conceiving of it as a plan or intention. I don’t know any Christian theologian who would reduce “Creation” to “design”.
If I say, “God designed the living cell,” I’m saying nothing more than that God, in advance of the first cell’s existence, had the layout of all the organelles etc. in his mind, and all of their complex interactions; but if I say, “God created the living cell,” I’m saying something much more, i.e., that God brought the living cell out of the world of his mind and into physical reality. The meaning of the two terms is quite distinct, and if they are carefully used, there should be no confusion.
I know that some of the BioLogos and ASA critics of ID have confused “X is designed” with “X was brought into existence by miraculous, non-natural causes.” For example, Dennis Venema seems convinced (despite an explicit statement of Behe to the contrary) that Michael Behe insists that everything that is designed must be created by supernatural intervention. That is, Venema seems to equate “designed” with “supernaturally created.” Is that what you are thinking about? If so, I agree that this is a bad confusion, and I’ve tried to address it, time and again, on various blog sites. But many TEs have been reluctant to let go of this blurring together of the two terms, for reasons of their own.
I agree that if anyone confuses “create” with “design,” this will create all kinds of problems for discussions of origins. But I don’t think we have to replace “design” with “craft” in order to avoid this problem. I think we simply need to insist on the fullness of the Christian meaning of “creation,” and then the distinction of “creation” from “design” will be easily perceptible.
