Enki played the Saviour role to Mankind. He was the creator of 'the Adam'; one of the Terran Human races of Mankind - 'the primitive worker'. He thus understandably termed the doomed earthlings 'my humans'. As chief scientist of the Anunnaki Humans, he could select, obtain and provide 'the seed of all living things' for preservation. He possessed the knowledge of resurrecting animals from their seed DNA. He was also suited to the design of 'Noah's Ark' - a vessel of a special design which could survive the avalanche of water.
The specially designed board was described in Babylonian sources as a 'Tzulili - a term which even today denotes a submersible boat - a submarine. The Sumerian term for such a vessel was MA.GUR.GUR meaning 'a boat that can turn and tumble'.

Ea enjoyed sailing E.DIN's waters alone owith mariners, when in setting up the gold-mining operations around South East Africa, he also organised the transportation of ores to the E.DIN in cargo vessels.
