The Great Sphinx of Giza,

Is the largest monolith statue in the world, standing 73.5 m (241 ft) long, 6 m (20 ft) wide, and 20 m (65 ft) high.
It is the oldest known monumental sculpture, and is commonly believed to have been built by ancient Egyptians in the third millennium BCE.
The Great Sphinx faces due east and houses a small temple between its paws.

Most Egyptologists believe that the Great Sphinx was created by the Pharaoh Khafra (Hellenized: Chephren) and that the Sphinx therefore dates to his reign (2520-2494 BCE). Some Egyptologists have put forward as models for the Sphinx different members of the royal family, including Khafra's father, Khufu, and his 'brother', Djedefre, and some geologists have suggested theories dating the Sphinx to various periods before Dynasty IV.

Orion Correlation Theory

This theory was originally posited by authors Graham Hancock and Robert Bauval, in a series of separate and collaborative publications from the late 1980s onwards.[26] The basis of the theory is the proposed exact correlation of the three pyramids at Giza with the three stars ζ Ori, ε Ori and δ Ori, together forming the asterism commonly called Orion's Belt, in the relative positions occupied by these stars in 10 500 BCE. Extensions to the theory concern the geographic relationship of the Sphinx, the Giza pyramids and the Nile as a reflection of Leo, Orion and the Milky Way, respectively.

The hypothesis has been examined by several scientists, who have published detailed criticism and rebuttal of these ideas, including two astronomers, Ed Krupp of Griffith Observatory, Los Angeles and Anthony Fairall, professor of astronomy at the University of Cape Town, South Africa. Using planetarium equipment, Krupp and Fairall independently investigated the angle between the alignment of Orion's Belt and North in c. 10 500 BCE and found that the angle differed considerably from the "perfect match" claimed by Bauval and Hancock in their Orion Correlation Theory: 47-50 degrees (planetarium measurements) compared to 38 degrees (pyramids). Furthermore, Krupp highlighted that the pyramids' line bent northwards, whereas Orion's Belt has a "kink" to the south, which had led Bauval and Gilbert to invert the pyramid map in their publications without revealing they had done so.
The Orion Correlation Theory and other similar hypotheses are used to support an overall belief in an ancient and technologically-advanced, but now vanished, global progenitor civilization (often Atlantis), a theory rejected by most archaeologists.
