Some people want to believe that a belief in God is not necessary in order to have good morals. They believe their morals are correct because they want to believe them regardless of whether these morals are based on something more solid than just their feeling. Thinking God is necessary to help us construct good morals is different than thinking that God exists. Remember, Satan believes God exists but he and the other fallen angles don’t live or exist with any morality other than to steal, kill and destroy. (John 10:10)
