I did not say these granite boxes are ‘uncompleted’.
My understanding is that they are not finished as perfectly as Dunn and his supporters would have us believe.
As for your, ‘What about the perfection that is there.’, we have to ask: Could this perfection be more by accident than design?
Then there are the imperfections we see in the Great Pyramid’s granite sections, and the fabulous Hattusha city (‘cut out of granite’) to be taken into consideration.
Prompted by your comments here, I have just ordered from Amazon UK a copy of Dunn’s ‘Lost Technologies of Ancient Egypt: Advanced Engineering in the Temples of the Pharaohs’.
So few answers - and not one of them mine.
