They aren’t. They’re all made up stories, its just that some have been maintained in the culture that some people still believe they’re true. A lot of the reason for their staying in culture have been societal pressure and the indoctrination tactics within the religious doctrines themselves that stop people questioning them.
“Mythology” doesn’t mean “Religion we don’t believe in”, it means a collection of stories. One does not exclude the other, you can have religion without mythology and mythology without religion, but you can also have religion with mythology. Most living religions *include* mythologies as components. The Christian mythology is a thing and is mainly the collection of stories found in the Bible. Islam mythology is in large parts overlapping with Christian and Jewish mythology, but also includes the stories of the Prophet. Hindu mythology is the stories of all the Hindu Gods, contained f.i in the Puranas and the Ramayana and Mahabharata epics.
What separates religion from mythology is that religion includes all the “practical” aspects of organised religion on top of their stories: how is the religion practiced, what are their clerical hierarchies, what rituals do believers perform, what is the structure of the religious practices, what do the humans that actually believe in this religion do in expression of their faith, do people worship in special buildings or out in the woods, and so on and so forth.
The story of the last supper is Christian Mythology. The real-world ritual of the eucharist is Christian religion.
A meaningful distinction between these two terms would be one that defines mythology as _a part of religion_. The Biblical stories would be Jewish and Christian mythologies, but there are also other components to Christianity (ethics, organization, practices etc.)
You cannot, however, make a meaningful distinction that would e.g. make the voyage of Argonauts “a myth“ and e.g. Exodus “not a myth”. Without any judeo-christian dogma, you just have to admit they are both myths of their respective cultures.
On a tangent note — there is also no objective demarcation between “religion” and “superstition”; between “liturgy” and “magic”; or between ”iconodulia” and “idolatry”. All these demarcations require you to accept some religious dogma as “true”.
They are literally two words with two different meanings:
Mythology: the collection of myths of a people, concerning the origin of the people, history, deities, ancestors and heroes.
Religion: belief in a spiritual or metaphysical reality (often including at least one deity), accompanied by practices or rituals pertaining to the belief.
“mythology” and “religion” are different because they are two words with literally (and I mean “literally” as “literally”) two different meaning.
