Everyone knows what action of others makes them happy or unhappy which means everyone knows how to act towards others, which means there is no need for Scriptures--a fact God knows--hence did not authorize writing of any scriptures in the world.
If we take the other option that God would use scriptures, there there is greater problem: We have an ocean of scriptures with all their interpretations. Among them, which is the right one? If Bible is chosen after sufficient debates, there is still problem. Among the 66 books that make the Bible, which one is true as most of them contradict each other? So are the case with verses. In one place it would say: "You are dust; unto dust you would return" which is flatly contradicted in other parts (Ecclesiastes 3:5; 12:7). Question about God is even worse--over 2000 years of debate among Christians have not yet finalized who is the God of the Bible!
