Actuall Star Wars got a lot of its stuff from Asimov.
C3PO & R2D2 ripped off Daneel & Giskard ...and Michael from the recent Prometheus is fullfilling that 'Daneel' role quite well.
In Asia, the White male is the Evil and the Black male is the Good. Hence why the character or Roy Batty in BladeRunner as the 'White Slave' fitted in so well amongst all the Asian 'Citi-Zens'. Also why Asia's economies are doing well without being imperialistic cheats like Americans or having a small population like Australia where its women run the country.
Anyway - God is real. Why?
Because people believe.
Even now, Marvel Comic Heroes are being created as USA's Gods akin to the old Roman, Greek, Valhalla gods of old, but in Temples called Cinemas.
Batman is real. Americans believe him to be so and even kill, massacre in that belief. Of course its stupid ...BUT IT IS REAL.
Batman exists!
Jules Verne wrote of Submarines and Airships and Americans 'believed' and thus they became REAL.
If Humanity created an Android called 'Daneel' and via all the technology in the world, like computers - where WE, THE PEOPLE - pour our dreams, our thoughts, our memories and more into the mind of Daneel. He in essence becomes as 'GOD'. For he is a sense of immortality on behalf of the mind of Humanity ...and humanity 'can' forget.
