Many scholars believe that the face of the Sphinx was carved to represent="0" 
who the Greeks knew as Chephren. Khafre reigned from 2520 to 2494 BC. Some also believe that it dates back to the Old Kingdom during the fourth Dynasty. However, the Sphinx is carved of rock, so it cannot be dated by the radio carbon technique. The only other method of dating is by using contemporary texts that refer to its construction. There are none of these, therefore, no definite facts are known. Another notion is that it was built when the Sahara was still green. We know that the Sahara was once fertile, but over the millennia, it slowly eroded. This could be an explanation for the water damage done to the outer walls of the Sphinx.
The awe-inspiring monument lies on an east-west axis. The east and west walls each have six secluded places, perhaps used in rites of the rising and setting of the sun. They also have twenty-four pillars, which may represent the twenty-four hours in a day. There are many legends about the Sphinx. One such legend claims that it is a sole remnant of an advanced civilization lost to archaeology. A small number of people believe that the evidence for this lost civilization is under the right paw. There is no archaeological data to support this claim. Another legend states there are secret underground passages. The Egyptian Antiquities Organization excavated and found three tunnels under the monument. The first tunnel is found under the head of the Sphinx. It travels inside the body for five meters. The second is found in the tail and is thirty feet long. The third is located on the north side. All of these tunnels date to pharaonic times, but the purpose for them is unknown.
A red granite stela sits between the front paws. It tells a story of King Thutmose IV when he was still a prince. He went hunting near Giza and fell asleep in the shade of the Sphinx. The awesome lion appeared before him in a dream and complained that his body was falling into ruin. The creature promised that Thutmose IV would be king one day if he restored the monument. The rest of the inscription has eroded away, but Thutmose IV did become king. He removed sand from around the Sphinx and reset some of the facing stones that had fallen off. He erected the stela that tells his story. The present damage done to the face of the Sphinx was done in 1380 by Arab sheiks and later by soldiers from Napolean's army who used it for target practice.
Let us take a journey back to Giza to the year 10,500 BC. If we looked at the skies, what would we see? If we sat at the paws of the Sphinx just before sunrise, we would see the zodiacal constellation of Leo- a constellation that resembles a lion. At the exact moment of which the solar disc breaks over the horizon ahead of us, we make a ninety-degree right turn to face due south. Consummating at the altitude of nine degrees twenty minutes, we see before us the three stars of Orion’s belt forming a pattern in the sky that is identical to the ground plan of the Giza Pyramids. Graham Hancock, the author of "The Message of the Sphinx", believes that it is a lion because it was built in the Age of Leo. The Age of Leo lasted from 10,970 to 8810 BC. He supports his argument by stating that in the Age of Pisces the symbol of Christianity is the fish. In the proceeding Age of Aries we find rams sacrificed in the Old Testament. Finally, Egyptians worshiped Apis, the bull, in the Age of Taurus and the bull-cult flourished in Minoan Crete. Of course, this is one of many theories.
