text: AN.U was the ruler of the ANNANAKI, or "those from heaven to earth came"; he was the first to set foot on Earth according to ancient Sumerian tablets. He piloted a craft from Niburu to Earth to look for gold to mine and grind into a powder to form an orbiting cloud of gold dust, probably to protect its atmosphere from dissipating into space anymore than it already had from its very elliptical solar orbit.
