I think a more realistic way to attack this issue is the exact same way I attacked the Pyramid Texts; context. Simply stated we need to know their import and export products to provide a good understanding of their technology. Egyptologists assume that everything was religious. Papyrus was exported for writring religious texts, myhrr was imported for religious ceremonies, etc.

I seriously doubt it! There was consumer demand so quite probably some imports were chiefly about satisfying such demand and some might be trivial such as turquoise from Afghanistan for baubels. It's possible as well that there was a technological demand for this and nothing should be written off as impossible. But just as today most imports and exports of most countries represent technological needs and uses.

The knowledge of the people can be deduced from not only the sophistication of these products and their artifacts but also from the nature of them. None of these were invented nor discovered through superstition and magic so it is highly illogical to assume all the uses were for superstition and logic. The paradigm is a frankensteins monster made of teflon because it is cobbled together from disparate things and nothing will stick to it except through magic. It is illogical, nonsensical, and wholly unevidenced.
