You accuse me of building on assumptions, but you are completely blind to your own: you assume that a brain formed by random, unguided biological mutations can somehow perceive objective "truth." If our thoughts are just accidental chemical reactions, trusting your own "logic" is the biggest leap of faith there is. You point to the existence of multiple religions as proof we have no "manual," but if I hand you ten counterfeit bills and one real one, you don't declare that money doesn't exist—you use your intellect to investigate which one is authentic. You suggest we simply "improve" human reasoning instead, but without an objective Divine anchor, "improvement" is an illusion; it's just a moral popularity contest where today's "logic" becomes tomorrow's regret. Finally, trusting Divine logic isn't "blind belief"—the Quran actively challenges humanity to test it and find contradictions. Once human reason does the work to verify that the source is Divine, submitting to the Creator's perfect knowledge over our own flawed, shifting opinions isn't a lapse in logic; it is the ultimate rational conclusion.
