Enlil dreamed the mysterious Galzu, whom he thought represented the Creator of All, warned him that when Earth moved zodiacally from the Enlil’s age--the Age of the Bull--to the Age of the Ram, Marduk would rule the Earth. In the dream, Galzu told Enlil "a righteous and worthy man must be choosen, by him and his seed will Civilized Man be preserved! " Enlil told no one of the vision but prepared to create a mobile general who could stop incursions by Marduk and his son Nabu. 

Enlil ordered his son Nannar to have Tirhu, Nannar's high-priest/king [ie, hybrid of much Anunnaki ancestry] establish himself in Harran at the headwater of the Euphrates (in what's now Turkey, near the Syrian border) the trade center in Hatti, land of the Hittites.  The Euphrates flows from Harran to the Enlilite capital, Ur.  Harran's also at the crossroads of the trade and military land routes to the postdeluvial spaceport in the Sinai.  [Sitchin, 2007, The End of Days, page 73]

"The failure of the War of the Kings to subdue the rebel land secure the landing place, led him to send his Champion, Ninurta to supervise and alternate spaceport in Peru.  Enlil, too, had been away from Sumer, and he returned to find that the Elamite legions--Ninurta's Foreign Service garrisoned in Sumer-Iraq had gotten out of control and committed what the gods considered to be "sacrileges."  

Enlil summoned Ninurta to account for his Elamites' crimes but Ninurta put all the blame on Marduk and Nabu, so Enlil ordered a council to try Nabu. In the council meeting, Utu-Shamash, the Spaceport Commander, accused Nabu of aggression. "Nabu blamed Ninurta and revived old accusations against Nergal in regard to the disappearance of the pre-Deluvial monitoring instruments and the failure to prevent sacrileges in Babylon. Nabu got in a shouting match with Nergal. Then Nabu accused Enlil of telling the Elamites to violate Marduk's temples in Babylon. ''There is no justice, destruction was conceived" Nabu shouted. Nabu's outburst, "an unheard-of accusation against the Lord of Command."

Enki defended Marduk and said that in Celestial Time (rather than the Zodiac Time Enlilites favored), Marduk should rule Earth. But Enki's other son, Marduk's jealous brother Nergal, blamed Marduk and Nabu for the turmoil. Enki told Nergal to shut up and stop obstructing Marduk and Nabu.

Enki and Nabu "argued so much that Enki shouted to Nergal to get out of his presence. The gods' council broke up in disarray." [Sitchin, Z., 2007,The End of Days, pages 87-88].
