What's the difference between religion and mythology?

Religion is a mode of worshipping a higher power of some kind.  Mythology is a narrative that reveals a hidden truth.  A religion is very distinct from a "cult", in that it allows people to come and go as they please, rather than requiring a material cost to join or exit.  A myth is commonly mistaken to be a "fiction or fable", likely because they use elements of storytelling.  

Mythology is an attempt to explain what is ineffable through using words.  This is an aspect of teaching religious/spiritual beliefs to gain some semblance of meaning and understanding of a deeper reality, beyond what we tangibly observe.  Intentional and unintentional human error is expected to erode the original teaching, especially over thousands of year, across language and cultures.  

Comparing religion to a big "game of telephone", doesn't invalidate the authenticity of people's beliefs.  Your take on the subject discounts untold volumes of research, history, and a fundamental sense of the origins of words.

Not very bright, are you.

Mythology is a corpus of stories and beliefs.

Religion, properly used, is a methodology for discovering truth, such as experiencing God for ourselves.

You really didn't think this through, pard.  Try again.

The only difference

is whether or not

you believe it to be true.

You are mistaken (a very common mistake).

The difference between the two can be CLEARLY seen

by comparing the standard English definitions:

https://www.dictionary.com/browse/religion

https://www.dictionary.com/browse/mythology

Now: most religions INCLUDE one or more mythologies.

When you refer to "Greek mythology" or "Norse mythology" or what-have-you

unknown to you

you are using those terms ACCURATELY

because you are talking about ***specifically the mythology***

and NOT the classical Greek religion or classical Norse religion, both of which are ***much broader fields of study*** than is the study of their respective mythologies.

Except in a very few cases

cases in which the ONLY thing known about a religion is the mythology

(and so scholars in writing equate the religion to the mythology)

when we say "mythology" we mean "specifically the mythology, not the whole religion"

and when we say "religion" we mean "the whole of the religion, including any mythologies it includes" and not "just the mythology of the religion".

So:

***religion does NOT become mythology***.

Religions often INCLUDE or INCORPORATE mythologies.

Nothing. They are the same fictional nonsense.

Depends upon the religion and the myth. 

They're exactly the same except that with religion, people still believe that mythical horseshit to be true and work hard to convince others (usually children) to believe it.

Billions of nutters actually believe religious nonsense.

Religions are about God / Supreme Being.

Mythology are about Myths.
