They certainly had the tools to shape granite... all one needs to do that is use hammerstones. It’s laborious but American Indians worked granite into discoidals, celts and spuds and the like the same way, albeit on a smaller scale.
Hammerstones?
Mainstream academia has made that claim for generations, but it’s never been proved or demonstrated that its possible to cut and perfectly finish multi ton granite blocks to microscopic flatness, with sharp right angles with those sorts of primitive tools.
Some years back, a Japanese team set out to prove that the ancient Egyptians could have quarried, cut, dressed, moved, and erected the stone blocks of the pyramids, using only the tools and methods they possessed in dynastic times.
Not only was the team incapable of fashioning multi ton blocks with those tools and methods, they wound up resorting to using modern power tools to fashion blocks of only a few hundred pounds.
After transporting their blocks to the building site with modern methods and equipment, they found they could not stack them into a tiny pyramid less than twenty feet in height.
Yet we’re made to believe the dynastic Egyptians built the Great Pyramid with 6.3 million stone blocks, averaging 2.5 tons apiece, using nothing but copper chisels, stone hammers, and brute force, in just twenty years.
Not only that, they were so precise in their planning and execution, the Great Pyramid is only out of perfect square by one quarter inch over thirteen acres.
That’s a level of perfection that can’t even be equaled today.
