Yup, as I posted above, there are places in Egypt where buildings were left unfinished and it is clear that they simply dragged the stones over sand. Basically they buried the building site in sand and later dug it out again, while dressing the stone from the top down. It is easy to do if you have enough people and time on your hands and they had those aplenty.
Anyone that actually lived in the middle east knows that sand is everywhere. They simply stacked the blocks while building up a sand pile around it, then eventually dug the sand away again, while dressing the stone from the top down to the bottom. There are actually some unfinished spots in Egypt where the tools of the trade and the gravel heaps surrounding the still partially dressed stone remained. There is no mystery about it in reality - only on TV.
