Sphinx carbon dating
It is clear to see that apart from Piazzi Smyth (and possibly Proctor), the dates for the creation of the pyramid are all considerably earlier than modern Egyptologists claim.
This is not due to a lack of science or rigor; On the contrary, the Radio-carbon dating at Giza supports the idea that the Great pyramid was built long before it is currently claimed by Egyptologists.
"Furthermore, it looks like Manetho "cooked the books," stretching out the history of Egypt as long as he could get away with, by adding years which did not exist, listing kings who shared the throne (co-regencies) as ruling alone, and dynasties as proceeding one after another, when many may have overlapped, especially during the intermediate periods.
Nevertheless, Manetho's history is still considered the foundation of Egyptian chronology.
While the Kings-lists are only able to offer us the sequence of Pharaohs, there have been two radiocarbon studies on the Giza complex which allowing us to put dates to the names on the list. In the 1980s several ancient Egyptian monuments, including the Great Pyramid, were radiocarbon dated.
Radiocarbon dating cannot be applied to stone, but it can be used to date fragments of organic material, such as wood and charcoal, which are sometimes found embedded in the mortar between the stone blocks.
The Sphinx Temple apparently gave radiocarbon dates of 2085 BC and 2746 BC (700 years apart).
A tomb just on the outskirts of the Giza site dates from the reign of the First dynasty Pharaoh Wadj (Djet), and jar sealings discovered in a tomb in the southern part of Giza mention the Third dynasty Pharaoh Ninetjer.
How does it affect the context of Ghiza, knowing that it was used before the Fourth dynasty?
This is in accordance with traditional theories about the pyramids.
The stone for this temple is believed to have come from the sphinx enclosure.
We have seen that the cartouches found in the 'Relieving chambers' are the best evidence yet for dating the site as the inscriptions run under and behind other blocks and therefore appear genuine.
