A piece of quartz stuck on the end of a toothpick will cut granite.... that's a fact. As for working granite with simple hand-powered tools I might suggest Stocks (2003) rather than an entwined UFO/fringe archeology aberration.

No one from the orthodoxy who actually know what they are talking about states the Sphinx is not water eroded...... after all, it erodes today every time it rains on exposed surfaces.

"millions of 2.5 ton blocks with tolerances of .010 inch"..... is that before or after ignoring the wide joints clearly visible all over the pyramid's core masonry? I will give you another chance to actually get it right......

A lapidary saw in a rigid jig is quite capable of making a very tight, smooth cut..... limestone is not that resistant to mineral abrasion. Calcite, the main mineral constituent of limestone, is only slightly harder than your fingernail, and is nowhere even remotely close to the hardness of diamond.
In the 1800s lithographic plate makers needed to produce flat surfaces on slabs of limestone so that they could get perfect registers and the slab didn't break under the repeated pressure exerted by the printing press. They became very skilled at doing this by hand with a levigator (i.e. a 10-12" cast iron disk with a handle sticking up from one side of its top surface), abrasive slurries, and a number of other simple lapidary tools. It's not really that complex and there doesn't appear to be any reason why the ancient Egyptian could not do this as well. A number of representations of rock polishing are presented in ancient Egyptian art. These appear to show stones used for smoothing, polishing, and shaping. They can be rectangular or round shaped blocks of rock with a flat smooth surface on one or more sides.
For a dynasty 18 example of a sandstone rubber for polishing type "UC395" into the search here [petriecat.museums.ucl.ac.uk].
The ancient Egyptians made these tools out of a variety of rock types, including granite, basalt, and sandstone (Clark & Engelbach 1930). These tools could be rubbed by hand back and forth or in a circular motion across the surface of the stone object with or without abrasive. Stone rubbers are generally used wet to prevent clogging of the grinding surface with rock dust, which lessens their effectiveness (Pond 1980).

Those the same ones claiming granite can only be scratched with diamond? Apparently they missed the physical chemistry and materials testing portion of that engineering course they took through correspondence or whatever. It's pretty clear a rather lacking understanding of basic engineering seems present too....
I seem to remember years ago pointing out to one of those individuals claiming "granite can only be scratched with diamond"... that quartz, the hardest primary mineral in granite, is nowhere close to the hardness of diamond (i.e. like about only 10% of such).
