By aligning the Sphinx with the rising sun at the spring equinox, he points to the Age of Leo, a period that occurred around 12,500 years ago due to Earth’s slow axial wobble known as precession. This astronomical alignment, combined with geological evidence of heavy rainfall erosion (More Information In Part: 3), suggests the Sphinx was designed as an equinoctial marker honoring a much earlier age
