The story of the Genesis Ark, while using characters from the Sumerian Ark story as well as the flood story's of the Greeks but in a futuristic dystopian nightmare chalk full of ancient astronauts, a suitcase which contains the DNA and the genetic sequencing of all life on the Deluvian earth. Featuring City States high in the atmosphere.All powerful beings so far advancedfrom our homonid ancestors that they'd genetically altered them to be a slave labor force but instead mimic our god like creators until they decide we'd tasted the fruits of knowledge, if we stumble on the secrets of eternal life we could be as the gods themselves.
Some background on the Greek Characters I'd use in the story as a focal point:
Warned by his father, the immortal Titan Prometheus, Deucalion built an ark to survive the coming Bronze Age-ending flood that Zeus sent to punish mankind for its wickedness. Deucalion and his cousin-wife, Pyrrha (daughter of Prometheus' brother Epimetheus and Pandora), survived for 9 days of flooding before landing at Mt. Parnassus.
All alone in the world, they wanted company. In answer to this need, the Titan, and goddess of prophecy Themis cryptically told them to throw the bones of their mother behind them. They interpreted this as meaning "throw stones over their shoulders onto Mother Earth," and did so. The stones Deucalion threw became men, and those Pyrrha threw became women.
I want to interweave a story of escape from a doomed but incredibly rich and robust socioty but the ultimate overlords decide they need to scrap our planet and let it heal by controling the populated areas with floods and ridding the planet of man who they've decided our the greatest evil, So Deucalion with the help of his father Prometheus, rescues his human mate and the Ark, outsmart Zeus and remarkably somehow survive into a sequel. Pandora's Revenge or Zeus strikes back.
