now if they would have made almost perfectly flat copper plates using stone hammers I could believe it , but almost perfectly flat stone using copper tools I just cant believe.
It all depends. Do you know how to make a flat surface on just about anything? You take 3 objects of the same material and start rubbing them together, alternating so that they are all three in contact that is 1-2 1-3 2-3. If you use just 2 they will wind up with one dished and one domed. But with 3 you can get 3 perfectly flat surfaces. In fact that has been the traditional way to make optical flats. The Egyptians were perfectly capable of figuring that out for themselves, it isn't really high tech, it just takes patience. And that is basically what it took for the Egyptians to cut and set all that rock.
