Religions try to answer important but mysterious questions like "Where did the world come from?" and "What happens to us after we die?" When people believe that they have answers to these questions, they often start new religions, or add their new ideas to old religions. Many religions believe in supernatural beings such as spirits, angels, devils, polytheistic gods, or a monotheistic god, who can influence people and the world. People who teach or write about religion often say that they got their ideas from a supernatural being. Also it depends on how much someone believes in their religion.
