 The Quran is wrong for a whole bunch of different reasons, but the bigger thing than that is understanding why there cannot be a hell, why that contradicts the notion of God. Pretend for a moment that there is a God, there still isn't a hell and Quran is still wrong. You said that you know that there is no hell. How do you know that? Nobody ever did anything so evil they would have warrant an eternity of being burned alive. Adolf Hitler, ISIS and so on, they deserve to be judged and punished because they were not punished in this life. What is the purpose of punishment? For their wrongdoing, for some people they get afraid wrong. You think that somebody who's done something wrong should be punished? Why? Why not? Can you tell me that? Why not? No, tell me why not? Because it is just.
