Eetoo

His mission is to leave this planet and search for answers that can only be found on the planet of humanity's birth. But nobody he knows has ever seen a ship that can sail to the stars - the kind their forefathers arrived on.
Eetoo is an orphan caring for the small flock of sheep he inherited from his parents. The only one he's close to, Venerable Too Dah, who taught him to read the ancient tablets, now tells him he must find his way to the planet of Humanity's birth and find the golden tablets that will complete their knowledge of truth. His own dreams also confirm it. But how?
He unexpectedly meets someone who gives him a lift off his planet, and his journey begins.
On his search, he discovers how evil the ancient humans were who first left Earth to colonise the stars. Though the ancient Nephteshi Human Empire is a thing of the past, some alien species have painful memories of their atrocities, and would rather see humanity extinct. The paradox keeps Eetoo searching for answers, taking him to first century Earth
Other galactic species are more friendly to humanity, and Eetoo gains the friendship of both humans and non-humans, including some romance.
Think: Ben Hur of Science Fiction.
The parts of the narrative set on Earth are influenced by readings of first century history in light of the Dead Sea Scrolls, the Pseudepigrapha, Rabbinical sources, as well as readings of Shalom Asch's The Nazarene. Some study of Quantum Mechanics also helped. Such a combination of rabbis, Essenes, and aliens could only exist in a historical space opera.
