Religions are things that people believe in and practice. They usually involve believing in a god or gods, and following a certain set of rules. Religions have been around for a very long time. Over time, they have changed and developed, but it is thought that they began because of something called evolution. Evolution is the process by which different kinds of animals, plants, and humans change over time. Evolution explains how we as humans, animals, and plants have changed over time. Through evolution, people started to believe that there were things that were greater than them, like gods or other supernatural beings. This is how religions were born.
