Religions are systems of belief which deal with the supernatural? - what happens to us when we die, the nature of Deity (or Deities) (cf God) and our relationship therewith. Most religions begin when Deity intervenes in the lives of a person or group, enlightening them and establishing a superior way of life leading to internal peace in this life and qualification for some kind of Heaven after this life.
Religions deal with the (more or less) divergent lifestyle?s espoused by other religions in several ways. Religions with more closed sets of beliefs may consider all the others wrong, corruptions or counterfeits of the true faith, while more open religions praise all belief systems as beneficial.
Extinct, ancient polytheistic religions, such as those of ancient Greece, [ancient Rome]?, [the Vikings]?, etc., are often studied under the heading of mythology. More exactly, the stories and legends around these beliefs comprise the mythology of one of these religions. More generally, by extension, for the non-adherents of any given religion, the stories and legends thereof are sometimes referred to (but usually pejoratively) as the mythology of that religion.
