Is the question of to believe or not to believe as simple as right and wrong? (Hint... Yes)

Some atheists, probably most are truly certain that all of the religions are nonsense. Most religious people believe that all but THEIR religion is nonsense.So two things: 1 close to 100 if not 100 % of the world’s population think that most or all religions are nonsense2: Atheists and Theists AGREE that most or all of the worlds religions are nonsense. So why are we arguing? We all agree. Religion is nonsense?
