I think myth is trying to explain how the world came into existence without some supernatural element. No matter what theory you look at, eventually you get back to something that can't be explained without creation.
The big bang theory starts with the notion of a cosmic explosion that caused matter to be hurled in all directions. So then, under this theory, the question becomes how did the original matter come into existence?
"The big bang theory starts with the notion of a cosmic explosion that caused matter to be hurled in all directions."
Actually, it wasn't an explosion but the expansion of the universe.
BTW, the Big Bang has nothing to do with the Theory of Evolution.
The original proposal for the "Big Bang", before Hubble, was by a religious astronomer who was seeking a way to scientifically detect God.
Which is the same thing that IDers are doing.
I'm just amazed that it's the religious folks who now reject the Big Bang, when they could as easily point to it and say "there is the evidence of God".
the question becomes how did the original Creator come into existence?
Both questions have difficult answers.
