It's a fantastic piece and no doubt the product of a master crafter. A huge amount of time and skill obviously went in to it and i expect that the workshop floor was littered with ones that just didn't make the grade as perfection was strived for. But no advanced machinery was required to make it - doubtless there are all sorts of jigs, tools and techniques that were used that we no longer know about that in them selves would be mind blowing to an enthusiast, but it's amazing what can be achieved with things like pole-lathes and pump drills (etc) with the right shaped drill bits and disks attached to them.
Power tools rarely allow us to make craft work that would have been impossible in times past, they typically just reduce the time and sweat required to finish a task.
Precipitation-induced weathering is seen on the body of the Sphinx and in the ditch or hollow in which it is situated. This gives a rolling and undulating vertical profile to the weathered rocks and is very well-developed and prominent within the Sphinx enclosure. The rocks displaying this mode of weathering also often contain prominent vertical crevices and other solution features, as well as cross-cutting diffusion fronts. Many of the vertical and inclined solution features follow joints and faults in the bedrock.
Of the four modes of weathering listed above, some rocks may show one mode overlain by another-thus, in particular cases, the various modes of weathering may be somewhat difficult to sort out. On the whole, however, they are clear and distinct from one another at the Giza site.
What is interpreted as precipitation-induced weathering is the oldest predominant weathering mode identified on the Plateau. It is found to any significant degree on only the oldest structures there, such as on the Sphinx body and the walls of the Sphinx enclosure. Of course, it still rains at Giza on occasion, and thus precipitation-induced weathering can be said to exist on all structures on the Plateau to some small degree; here we are talking in generalities and attempting to look at the broad picture. In many places this precipitation-induced weathering mode has superimposed upon it wind-induced weathering. Presumably the major portion of this precipitation-induced weathering occurred prior to the onset of the current and regime exhibited at Giza (i.e., prior to the modern climatic regime of the Sahara Desert).
On the Sakkara Plateau, some ten miles (sixteen kilometers) to the south of Giza, there are fragile mud-brick structures, mastabas, that are indisputably dated to the First and Second dynasties-presumably several hundred years earlier than the standard dating of the Sphinx-that exhibit no evidence of the precipitation-weathering features seen in the Sphinx enclosure. As noted above, well-documented Old Kingdom tombs at Giza, cut from the identical sequence of limestones as the body of the Sphinx, exhibit well-developed wind-weathering features, but lack significant weathering which is precipitation-induced. For these reasons it can be concluded that the well-developed precipitation-weathering features seen on the Great Sphinx and its associated structures predate Old Kingdom times and, in fact, may well predate dynastic times altogether.

Thank you! Finally some one provides evidence that I can examine. I'm open minded on the subject and not afraid to admit I was wrong. I just got super busy with work but I will read though these. Again thank you.

If the Egyptians were so advanced, why didn't they build any bathrooms?
By 2500 B.C. the Egyptians were pretty adept with drainage construction, accentuated by the significance that water played in their priestly rituals of purification and those affecting the burial of the kings. According to their religion, to die was simply to pass from one state of life to another. If the living required food, clothing and other accoutrements of daily life, so did the dead. Thus, it's not surprising that archaeologists have discovered bathrooms in some tombs. Excavators of the mortuary temple of King Suhura at Abusir discovered niches in the walls and remnants of stone basins. These were furnished with metal fittings for use as lavatories. The outlet of the basin closed with a lead stopper attached to a chain and a bronze ring. The basin emptied through a copper pipe to a trough below. The pipe was made of 1/16" beaten copper to a diameter of a little under 2".

You do know that you can't carbon date stone, right? Archaeologists can only carbon date organic material such as human remains or papyrus to determine the age of the civilization. a reply to: Harte
