Step-by-step explanation:
According to the Judeo-Christian tradition, God cast Satan out of Heaven due to Satan's rebellion against God's authority, his desire to be equal to God, and his questioning of God's decisions. The rebellion of Lucifer (Satan) is mentioned in the Bible stories, such as in Genesis and in the New Testament. It is believed that God, who is seen as all-powerful and all-knowing, is not responsible for the evil in the world, but rather it is the result of the actions of a fallen angel and humans' weaknesses and temptations. The existence of evil has long been a difficult problem for religious believers to explain, but various theological perspectives have attempted to address this issue, such as by attributing evil to human free will and the process of soul-making. Ultimately, the question of why evil exists and why God allows it is a complex and deeply philosophical one that has been debated by theologians and philosophers throughout history.
