If we took 100,000, 200,000 even, of the strongest most skilled, totally motivated manual laborers on earth today, with the top structural engineers in charge of them, and gave them the best food and accomodation, and all the necessary tools, raw, materials and stones that the ancient Egyptians had, all readily to hand, but no power tools or use of electricity, is it within our purview to be able to build a Great Pyramid today?
If not, why not?
Approximately how long would it take?
And if they were allowed all the latest power tools, cranes, tractors, diggers etc? Could they do it, even then?
