Why are the stories of ancient religions considered “myths” while those of christianity and judaism are given credibility?
Western civilization has gradually moved from a multi-god to single-god concept over time. One reason may be that myths were largely communicated by oral tradition, while the single-god concept was written down. Myths were geocentric too, with the Vikings, Celts, Romans, Egyptians and Greeks having their own names for gods, accompanied by stories. When those ancient civilizations disappeared, so did belief in their system of gods. Judaism, Islam and Christianity, based on books which followers believe are inspired by a single god, are considered more sophisticated approaches defining a god and man’s relationship to that god. These current religions are more universal in scope, probably because their traditions are written and accessible to many cultures. In a practical sense, maybe it’s easier to please one god than to try to figure out which god needs to be pleased in what way at what time.
