Eetoo

Eetoo knows that humanity didn't begin on this planet - the tablets tell him so. His people live simply in small villages dotting the arid landscape, carrying on their tribal traditions. Eetoo, an orphan, raises the sheep he inherited from his parents. Now, Venerable Too Dah, the Keeper of the Tablets says that Eetoo is the one that the tablets say must go in search of the planet of humanity's birth to bring back the writings from another set of tablets, which will complete their knowledge.
Eetoo has also had dreams of finding those tablets. But no one has ever seen a spaceship before. How can Eetoo leave this planet, let alone find his way to the forgotten one?Heptosh arrives on such a ship, seeking to find out what happened to another civilisation that had shared that planet with Eetoo's people in the past, but had disappeared. He finds Eetoo, and asks his help, which Eetoo gives in return for a lift off the planet.
Heptosh takes Eetoo back to his home planet, and acts as his guardian. However, even there, no one knows the location of the planet of humanity's birth. Eetoo makes friends, there's romance, and he meets other space beings, some friendly to humanity, some hostile. He learns that the first human civilisation to reach the stars was cruel and unjust; a menace to other civilisations. That is why some would prefer it if humanity became extinct, as human nature predisposes humanity to follow that path.
This only adds to the questions that weigh on Eetoo's mind - all the more reason to seek what answers can be found on the planet of humanity's birth. When he arrives, we find that it's the first century AD. This could be defined as Historical Fiction, well researched, but most definitely, a Space Opera. Neither aspect reduces the effect of the other. Let's just call it "Historical Space Opera". Think: "Ben Hur of Science Fiction".
