Do You Think the Dynastic Egyptians were Responsible for some of these Advanced Artifacts

We have examples that very much match the Primitive toolsets and techniques found in the archaeological record and we also have examples like this box at elephantine. Island that undeniably do not instead these show evidence for remarkable Machining and Precision or have other aspects of manufacturing that are far beyond the capabilities of primitive handheld tools. Considering these facts and facts of what they are. There are two possibilities here either both of these industries. The Primitive and the advanced existed alongside each other at the same time during the dynastic civilization or they didn't and therefore the dynastic Egyptians could not have made such objects. This must therefore mean that the more advanced industry was from an older time period one lost to history and from a presumably far more advanced civilization whose artifacts were eventually inherited and then reused by the dynastic civilization as we know them.
