Astronomical Connections

It is stated that all three pyramids are always active and have symbolic meanings related to the cosmos, with:

- The pyramid of Cheops connected to Orion.

- The pyramid of Chephren referencing Alpha Centauri.

- The pyramid of Mycerinus linked to Pegasus.

It is believed that the construction of the pyramids may have been influenced by extraterrestrial civilizations such as the Anunnaki, based on:
