In many fictional works where Christianity, Judaism, Buddhism, and the other assortments of religion don't exist there are usually made up religions. Or, the opposite happens and there is no mention of religions whatsoever. That does not mean religion doesn't exist in that world, but it just isn't mentioned. Often times there are different religions that clash such as the Faith of the Seven and the believers in R'hllor in Game of Thrones. The difference between this and Mythopoeia is that while a myth is generally a belief in a god that is rarely worshipped anymore(ex: Zeus), a religion is the worshiping of a god that many people believe in(ex: Buddha). An example that is mythology would be people a story taking place during the time when Greece was a great empire.If there is proof that the gods exist, then that would be a religion. However if there is a story that takes place in modern times in which the Greeks belief in many gods is generally not believed, and there is no proof of it, then the Hellenistic religion of the Greeks would be mythology. No Real Life Examples, Please!, for obvious reasons.
