I wish an anti-theist was the franchise creator, one who very clearly saw the flaws of faith/belief as a concept and realized that people would better off without any of it.
The Force would just be a genetic abnormality that some humanoids can use for foresight and telekinesis. The Jedi and Sith both ascribed religious power to it and abused said power for millennia. Luke, being the first to divorce religion from this power, leads in a new enlightened age of discovery.
Nah, that sounds really pretentious and cold.
