After several unsuccessful attempts to create Earthling workers, the team implanted a zygote (female apewoman's ovum fertilized in a test tube by male Nibiran sperm) in Ninmah's womb.  She delivered the child, named it Adamu.  To duplicate Adamu, Ninmah implanted test-tube hybrid zygotes from apewoman eggs fertilized by Nibiran sperm in the wombs of seven female astronauts from her Medical Corps.  All the resultant seven hybrids were male.   

Ningishzidda then created a zygote to develop into a female hybrid. He implanted this zygote into Enki's spouse, Ninki.  Ninki carried the fetus, who emerged as Ti-Amat, a sandy-blonde female.  Ningishizzida cloned Ti-Amat's essence into test-tube zygotes and implanted them in the same seven Med Corps women who bore the hybrid males.  All of the surrogate mothers carried female hybrids, again delivered by caesarian. The seven female and the eight male hybrid clones were put together in cages in the African lab.  The clones copulated frequently, but the females did not conceive.

Enki, Ninmah and Ningishziddha concealed the fact that they'd genetically changed Ti-Amat so she could reproduce.  Enki brought Ti-Amat and Adamu to his place at the head of the Persian Gulf.  Ti-Amat and Adamu wandered in Enki's orchard at the head of the Persian Gulf while Ti-Amat's fetus, the first bred from hybrids, grew inside her.

Enlil discovered Ti-Amat's pregnancy.  He raged when he realizing the hybids could henceforth breed among themselves.  Enki’s team had exceeded its mandate to make workers.  He, Enlil, Commander of the Mission, did not authorize Enki's team to create a new species.  

Enlil rebuked Ningishziddha.  But Ningishziddha said he'd withheld the Nibiran longevity gene from the hybrids.  Enlil appealed to the Council on Nibiru, but the Nibiran Council, desperate for the new primitive workers to mine Earth's gold to save Nibiru's atmosphere, ratified breeding hybrids.  Enlil angrily expelled Ti-Amat, Adamu and the seven hybrid males back to Zimbabwe to breed as miners.

           Rockets from Nibiru (then in elliptical orbit around the Sun every 3,600 years) reached Earth best when Nibiru neared the Sun, at perigee. But at perigee also, Nibiru 's gravity disturbed planets of the inner solar system.  Perigee also affected Nibiru's atmosphere.

One of Nibiru's perigees, more than 350,000 years ago, disturbed the atmosphere and prompted volcanoes and earthquakes on Earth and Mars.  "Kingu, Earth's Moon, was also affected" by mighty winds and "brimstones falling." Marduk (Enki's son who ran the astronaut base, smelting and transshipment facilities on Mars) reported Marsbase unusable and asked for re-assignment on Earth.  Enlil agreed and beamed King Anu on Nibiru that rockets should instead of transshipment form Mars, take gold directly from Mesopotamia to Nibiru.

Keep Marduk as Astronaut Boss and re-assign them to a moonbase, Enki told the King, "The netpull [Gravity] of Earth is than Lahmu's [Mars'] much greater. To overcome it our powers shall be exhausted. Let us an alternative examine: nearby Earth, the Moon....Smaller is its netpull, ascent and descent thereon little effort will require. Let us a way station consider, let me and Marduk thereto journey. Let the Moon be first examined," Anu to Enki and Enlil the decision beamed."

Though he okayed the Mars trip for Enki and Marduk, Anu shrunk Enkiite power, especially Marduk’s, (whom he’d agreed would succeed Alalu as Nibiru’s king) with the astronauts. Anu suspected Enki, Marduk’s father, abetted both the Igigi revolt Anzu led and also the miners' revolt in Africa. So the King ended both gold transfer on Mars and Marduk’s job as Mars Operations Boss. Anu also favored Enlil's lineage over Enki’s when he gave rule of the new spaceport (from which the gold would directly rocket to Nibiru) at Sippar to Enlil’s son's son Utu. 

"In a rocketship did Enki and Marduk to the Moon journey.  In a place of rolling hills they set the rocketship down. Eagles' helmets [eagle-shaped helmets] they had to don; the atmosphere was for breathing insufficient.  In the rocketship they made their dwelling. For one circuit [orbit = one Earth year] they remained.  [Sitchin, Z., 2002, The Lost Book of Enki, pages 153 -161]

The slaves, descendants of Adamu–Homo Erectus and Homo Neandertalenis hybrids [Sitchin, Z., 1995, Divine Encounters, page 47]--in the Edin, proliferated and, in addition to slaving for the Nibirans, foraged all over Mesopotamia.  The naked Adamite slaves cavorted, copulated and bred everywhere.  Their numbers grew.  They exhausted created food shortages.  Enlil, already angry Enki created fertile slaves, demanded he solve the food crisis. 

Enki  introduced plants and domestic animals for the slaves to tend but kept to himself a plan to upgrade slave intelligence with his genes.
