Here's why (they) love gold. The philosophers stone(monoatomic gold). In Egypt they called it MFKTZ. It was made at the temple of Hawthorne at Mt Sinai. "Moses burnt the golden calf in a fire, ground it to powder, scattered it on water, and forced the Israelites to drink".
Here's what i found. Mason alchemists saying the philosophers stone is a gold powder. The Egyptians thought it gave you powers and let you communicate with god. Same book with this talks about using the blood of infants
.

The idea is this special type of gold when ingested in large amounts increase the electromagnetic field of the body and cells. This study says it impacts how the brain works. Possibly allowing them to communicate with god at a higher vibration. Was used in other cultures also.
