By a social fact, Durkheim is referring to facts, concepts, expectations that come not from individual responses and perferences, but that come from the social community which socializes each of its members.
Religion provides social control, cohesion, and purpose for people, as well as another means of communication and gathering for individuals to interact and reaffirm social norms. Durkheim's second purpose was in identifying certain elements of religious beliefs that are common across different cultures.
