„Realities - The Great Pyramid “

Realities – Worlds or the states of things as they actually exist, as opposed to an idealistic or notional idea of them.

Pyramid – A monumental structure with a square or triangular base and sloping sides that meet in a point at the top, esp. one built of stone as a royal tomb in ancient Egypt although monuments of similar shape are associated with the Aztec and Maya civilizations and were used mostly for rituals.

So maybe all of these races found the Pyramids intact and used them for there own purposes. Scholars of course presume the word is from the Latin or Greek but in reality its origin is ultimately unknown.

This reality is mine, Eypgt, on the western bank of the Nilet River, the Great Temple city of Al Jizah.
This is the pyramid itself.
The only difference is the water, the one you imagine is in a desert and as being abandoned for thousands of years.
