Negative Charge Land Electric Potential Seeks (Anode) Positive Charge
Earth or Land is the negative electrode, separated by the dielectric air with the positive electrode ionosphere above. Opposite charges attract. Maintaining charge separation allows for the creation of Earths electric field, which in turn supports life shown by the ankh as the purpose of discharging into the Earth using Pyramids when using God Electric Hieroglyphs.
Nebemakhet Tomb on the central field at Giza explains the physics of maintaining charge seperation on the earth. See the hieroglyphs for Nephthys if you dont understand yet...
