How Do We Know It’S God’S Book?
If you are intellectually convinced by the arguments and you say so then that is being honest. Even if your feelings are different. But if you are not intellectually convinced and say so then you are not being honest, you need to evaluate why you believe in what you believe. Arrogance would be that you would just say “I don’t care about being convinced, I say whatever I feel like.”, this is not arrogance, just a case of honesty or dishonesty. You do need evidence to justify the doubt. Just because the doubt is old does not justify it as is the case with anything, something being ancient does not justify it. You need to make an argument what makes you think it’s a third creation, what creation even is it? What creation is it that built kingdoms for Israelite and Quraish as the revelations promised? Even if you call it another creation as you speculate and throw the narrative out of the window, how will you answer life’s issues? Do you not want to know where you came from? What happens after death? About morality, about desire for justice and immortality? That’s the point, Qur’an gives you the answer you seek, it is the answer you accept by default (even if you are not convinced), to throw all of this away, you need more than just a doubt, you need some evidence, something that makes you wanna go in the direction you are inclined to.
