If you asked me if souls are real or if God is real, I'd say yes to both

Having read your explanation, I think you ought to say both are not real. Your description of God and souls as parallelized cognitive algorithms does not predict what "God is real, souls are real" predicts.

I think it would be more accurate to say "the belief that 'God is real, souls are real' is definitely real, and regardless of the truth value of the statement, the belief itself affects the world". That makes the same predictions as your cognitive algorithm idea (which I quite like), but doesn't cause misunderstandings with people who are using the word 'real' in very common ways.
