Great sphinx of giza carbon dating
Taking all things into consideration, it seems that we must give the credit of erecting this, the world's most wonderful statue, to Khafre, but always with this reservation: that there is not one single contemporary inscription which connects the Sphinx with Khafre; so, sound as it may appear, we must treat the evidence as circumstantial, until such time as a lucky turn of the spade of the excavator will reveal to the world a definite reference to the erection of the Sphinx.
Apart from the Causeway, the Pyramid and the Sphinx, the complex also includes the Sphinx Temple and Valley Temple, both of which display similar design of their inner courts.
In 2004, Vassil Dobrev of the Institut Français d'Archéologie Orientale in Cairo announced he had uncovered new evidence that the Great Sphinx may have been the work of the little-known pharaoh Djedefre (2528–2520 BC), Khafra's half brother and a son of Khufu.
Dobrev suggests Djedefre built the Sphinx in the image of his father Khufu, identifying him with the sun god Ra in order to restore respect for their dynasty.
Although certain tracts on the Stela are considered good evidence, a purposeful fake, created by the local priests as an attempt to imbue the contemporary Isis temple with an ancient history it never had.
the royal son, Thothmos, being arrived, while walking at midday and seating himself under the shadow of this mighty god, was overcome by slumber and slept at the very moment when Ra is at the summit [of heaven].
Colin Reader, an English geologist who independently conducted a more recent survey of the enclosure, agrees the various quarries on the site have been excavated around the Causeway.
Because these quarries are known to have been used by Khufu, Reader concludes that the Causeway (and the temples on either end thereof) must predate Khufu, thereby casting doubt on the conventional Egyptian chronology.
The authors argue that the geographic relationship of the Sphinx, the Giza pyramids and the Nile directly corresponds with Leo, Orion and the Milky Way respectively.
Sometimes cited as an example of pseudoarchaeology, the theory is at variance with mainstream scholarship.
