Adapa and Titi, Enki’s son and daughter, mated. Titi bore twins, KA‑IN and ABAEL, the first ADAPite humans, humans with far more–due to Enki’s genetic infusion‑‑Nibiran genes relative to Erectus genes than their mothers, the ADAMite girls Enki impregnated. Enki schooled his (albeit clandestine) son Adapa. He ordered Adapa to teach his descendants–the enhanced Earthlings–to run farms, herds, estates and less enhanced Earthlings. Enki brought more Earthlings from Africa to Sumer for Adapa to train for the Expedition bosses’ homes and facilities.
Enki’s heir, Marduk, pre-empted Adapa’s son Abael and taught him how to tend goats and sheep Enki’s youngest son, Dumuzi brought back to Earth from Nibiru.
To counter Marduk and Kain, Commander Enlil had his son Ninurta teach Aba-el to raise the enhanced grain Ningishzidda’d brought from Nibiru.
Ninurta
Enlilites, the Commander insisted–not Enkiites–, would run Earth’s farming. So Ninurta taught Kai-in, Marduk taught Abael.

KA‑IN’S LINE PROLIFERATED
Enki took Ka‑in to Eridu for trail before Enlil, Ninki, Ninurta and Nannar of Enlil’s Lineage, Ninmah, and Enki, Damkina and Marduk of Enki’s (The Seven Who Judge ). Marduk, Abael’s mentor, told them to kill Ka‑in. But Enki revealed he begat Ka‑in’s father Adapa, so Ka‑in was Marduk’s grandnephew. “Ka‑in must live,” said Enki, “to breed superior Earthlings to work field, pasture and mines. If Ka‑in too shall be extinguished, satiation[of food supplies]to an end would come, mutinies will be repeated.”

Adapa told Ka‑in, “For your sin of your birthright you are deprived, but of your seed seven nations will come. In a realm set apart they shall thrive, distant lands they shall inhabit. But having your brother with a stone killed, by a stone will be your end.” Ninurta returned Ka‑in to the wilds east of Edin and ” begat sons and daughters.” Ninurta, “for them a city built, and as he was building, by a falling stone was Ka‑in killed.” Ninurta may have killed Ka‑in. [ZS, Wars : 112]
Ka‑in’s survivors planted grain. They founded and ruled the city of Nud [also called Dun, Dunnu and Nu.dun]. Sons of Ka‑in’s successors for the next four generations murdered their fathers. For the next three generations after that, each ruler of Nud killed his parents, married his sister, then ruled. Ka‑in’s son’s son’s son, Enoch, succeeded Ka‑in four generations later. Enoch married his sisters, Adah and Zillah. Adah’s first son, Jabal (and the sub‑lineage Jabal begat), lived in tents and herded cattle. Adad’s second son, Jubal, begat lyre and flute players. Enoch’s other wife, Zillah, bore Tubal‑Cain, a smith, “artificer of gold, copper and iron.” [ZS, Wars: 111 ‑112; Enki:, 181‑193]
ADAPA AND TITI’S OTHER PROGENY AND THEIR ISSUE SPREAD
Titi bore thirty sons and daughters to her brother Adapa. Nibirans divvied them up and taught them to write, do math, dig wells, prepare oils, play harp and flute. Nannar, Commander Enlil’s second son, gave these Adapites rituals to worship him and the other Nibirans as gods. Enki taught astronomy to one of his descendants, Enkime. Marduk rocketed Enkime to the Moon and Marsbase, then to the Spaceport at Sippar to oversee the Earthlings there for Shamash.
