A myth, is a truth, which cannot be told in any other way.
Rather than try to define something literally, try to understand its meaning.
e.g. we cannot say what the smallest particle of matter is, we have never seen it, yet we know something is there.
So we create a myth - the 'atom'. And even though we know that is not the thing, it still conveys its meaning. In a way we can all understand and discuss.
Whereas before, it was not possible to talk about it. Because we all had a different idea of what it meant to be. What was its meaning?
There is nothing in the material world who's meaning is not described in myth and symbol.
Yes, this is an extraordinary proposition. OK, show me that it is untrue?
Finally, try not to agree with me.
Look at what is happening in front of your face, while having suspended all prior belief systems.
