And I'm sure you, like most ppl, don't understand the term myth.
The common meaning of the word myth is a complete lie, a hoax, a fabricated event. Such as "UFO sightings are a myth kept alive by people so lonely that they want to believe something exists outside our solar system."
But this not what is said about the word's true meaning.
What Is The Difference Between Myth, Legend And Fable
A legend is a mostly historical event, with some elaboration. Like ghost tours of old houses, fish stories, or the tale of the Trojan War in Illiad/Odyssey. The point is to liven up a historical event. The Bible is not legend.
A fable is a deliberately untrue story that involves forest critters usually, and is supposed to provide a moral. Cinderella, Sleeping Beauty, Aesop's Fables, Paul Bunyan, all of these are fables.
A myth is something much more than a simple fable though, and it's not a legend either. It's something that may or may not be historical (yeah, geniuses stop trying to timeline the Bible to real history, it's not the point) but the purpose is not the history nor amoral lesson, but to explain how things work. Think of the story of Noah. It's a story of how the world is almost destroyed, yet God makes a promise (and shows it, every time you see a rainbow) that God will not try to flood the Earth again. This is a story though not just to explain about rainbows but about the environment and God's forgiveness. Or think of Moses who frees us from slavery. Ever been in a dead-end job where you get no appreciation? You hate it, but you have basically screwed up alot of jobs and are afraid to leave. Yeah that sort of job. If you understand being stuck, you understand someone promising a better life. And then there's Jesus.
