Also, regarding "To the question-did the AE have metals prior to 2,000BC...", I assume you meant "To the question of which metals the AE had..." to clarify that no one has questioned whether the AE had metals prior to 2000BC.
Finally, regarding those "swords" that dated to 3300BC, do you know how they were "dated", e.g., directly vs. through context? As you mentioned, they're copper, so there is no relevance to granite work during the OK. Also, if they are "swords", they appear to be strictly ornamental/symbolic since they do not have a functional guard or grip that fits a human hand. Or perhaps they were food skewers.
How can any of us ever know, when all we can do is think?
