There are extensive erosion patterns on the Sphinx and it's surrounding structures. It is normally accepted that the Sphinx got it's erosion because of the wind and sand as it was supposed to have been built around 2500 B.C. That area has been covered in desert since about 4000 B.C. so water erosion was simply never considered. Except by some geologists;
"In 1996, a pair of controversial Egyptologists claimed that rain, not just wind and sand, caused significant erosion of the Sphinx; geologists backed up their claim. Considering that the region's moist prehistoric climate shifted to current arid conditions around 4,000 B.C., rain damage would indicate that the Sphinx was built well before Khafre's time."

This is what
wind erosion looks like - the erosion pattern moves sideways:
This is what
water erosion looks like - the erosion pattern moves from up to down an creates cracks or fissures:
This is what erosion on the southern wall of the sphinx looks like:

Notice the wall behind the Sphinx, how the erosion pattern goes from up to down. Exactly the kind that water erosion would cause. Notice the Sphinx itself, how new it looks...it's because of a reconstruction project. Bricks have been placed all around the Spinx where you could previously see more water erosion.
Sphinx Reconstruction:
So basically the accepted theory is that wind and sand erosion caused the erosion of the Sphinx because if water erosion is accepted then the structure would have to predate the accepted dates of the Egyptian civilization.
Besides the obvious water erosion patterns there is also one simple fact that gets overlooked by conventional Egyptologists. Sand will pile up against rocks or stones and cover or mostly cover them.
If a stone is covered in sand then it won't get eroded by the wind or loose particles of sand. In other words, the stones are protected.
When Napoleon visited the Sphinx in 1798 it was covered in sand:
This picture is from the early 1900s when the Sphinx was being excavated:
In summary,
1. The Sphinx has water erosion patterns when it should have wind and sand erosion.
2. Sand piles up against rock. So the Sphinx has been covered in sand for most of its history, protected.
How could the Sphinx possibly have gotten water erosion while it was covered in sand?

At the end, you mean "wind erosion while it was covered in sand?" I believe, because water can sink through sand...
i don't think it has to predate dynastic egypt. there is a thoery that it predeates the great pyramid of khufu, though, becuase before the pyramid of khufu, water could run down the giza plateau and erode the sphinx. but that does not neccessarily mean it predates dynastic egypt.
I think people are missing the point... sigh*
