Pyramid coordinates 29.9792458

Speed of Light = 299,792,458

Could it be that our ancestors who built the pyramids (believing their future kin would be of advanced mindset) wanted all of their relatives to know the light (solar return) can be found in death (symbolic of what the pyramids represent, tombs)?

The Giza pyramids are precisely (some argue approximately) aligned with the constellation of Orion; the stars of Orion are associated with Osiris, the God of rebirth and afterlife.
