If they knew how to heat up limestone, and turn it into mortar, it would have made the task so much more easy.
The chiseled "stones" could in actuality be limestone powder, mixed on site, poured into molds, in place. There have been objections to this theory, but it does easily answer a question about how the huge stones were moved and assembled.
Something that I thought was really interesting was that the ancients had plywood which would make producing moulds easier.
It would also be a hell of a lot easier for the hired hands to tote wheelbarrows or baskets of material and jugs of water way up high than would moving 5000 pound blocks of rock.

X-Ray Analysis and X-Ray Diffraction of Casing Stones from the Pryramids of Egypt, and the Limestone of the Associated Quarries (1984) by Joseph Davidovits
published in Science in Egyptology, Proceedings of the Science in Egyptology Symposia, Manchester, U.K., pp. 511-520, 1984.
The hypothesis that the limestone that constitutes the major pyramids of the Old Kingdom of Egypt is man-made stone, is discussed. Samples from six different sites at the traditionally associated quarries of Turah and Mokattam have been studied using thin-section, chemical X-Ray analysis and X-Ray diffraction. The results were compared with pyramid casing stones of Cheops, Teti and Seneferu. The quarry samples are pure limestone consisting of 96-99% Calcite, 0.5-2.5% Quartz, and very small amount of dolomite, gypsum and iron-alumino-silicate. On the other hand the Cheops and Teti casing stones are limestone consisting of: calcite 85-90% and a high amount of special minerals such as Opal CT, hydroxy-apatite, a silico-aluminate, which are not found in the quarries. The pyramid casing stones are light in density and contain numerous trapped air bubbles, unlike the quarry samples which are uniformly dense. If the casing stones were natural limestone, quarries different from those traditionally associated with the pyramid sites must be found, but where? X-Ray diffraction of a red casing stone coating is the first proof to demonstrate the fact that a complicated man-made geopolymeric system was produced in Egypt 4,700 years ago.
