I wonder what you mean by 'advanced engineering'. The very fact that these huge monuments were built shows that the people - the people of that time - had the skills to do it and would have been justifiably proud of them, even though it must have cost many lives in the process.
"I have seen 5,000yr old fluted bulbous diorite vases in museums that look like they came of the manufacturing line yesterday that are infinitely more interesting from a technological standpoint than just "big blocks". And also Archae, the greater point to the rest of us, Hancock and Bauval notwithstanding, is the casual use of large blocks regardless of whether they be 50 or 150 tons."
What do you mean 'casual'? I doubt very much whether this was done in a casual way; it must have been the equivalent of today's feats of Mars rovers or something. If you are referring to Archae's assessment of the work, I'd say that the word 'casual' is nowhere in sight.
