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 haveanswers 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 amonotheistic 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.
Many religions are very old, but newreligions are always being created when some people aren't satisfied with the answers from the old religions. Things which are considered important and good by religions are called sacred or holy. Manyreligions have sacred books that give the most important ideas and stories of their religions.
Religions often teach how they believe people should behave in order to live happily together and/or toplease God. Many religions believe that people who live in the right way will go to a pleasant place, or (heaven), after they die, or that people who live in a wrong way will go to a bad place, or(hell). How long one stays in these places depends on which belief system is asked.
