Vatican image only reflects something known: the octagonal shape like Mayan 8-spooked wheel Stargate:

The Great Pyramid does have 4 walls but since they are somehow slightly curved, they create 8 walls as seen from satellite view... just like Dome of Rock in Jerusalen, Russian church plan, some Muslim pillars, Ching I mandala and so on. Key Lines, domes, pyramids...
The disc in Sumerian tablet does have an octagonal shape within and if that represents the Sun (or another planet or even a red star), don't disregard the fact there are smaller discs (smaller planets), harnessing the sound of all planets and the Sun?

The fact there's a GIANT seating on the throne indicates he's the one with that technology. Obviously he ain't a human being but the little ones standing in line. But I don't see these little fellows entering in whatver device but maybe helping. It seems sand is pouring from that device bending like a palm tree and creating the shape. Or is it clay rather than sand?

Where the hell is that giant? On earth? Why are there humans with him? I doubt they are in Nibiru. It seems the giant fellow was right here on "eretz" (earth) messing around with us for his purposes.

Incas and Egyptians associated GOLD with the Sun.
