Scientific laws are no more solid evidence than scientific theories. A scientific law is a simple, basic concept around which a science revolves. But they're not any more "evidence" than a scientific theory. That's why Einstein's "theory" of General Relativity supersedes Newton's "law" of Gravity.
Also, if you mean the literary definition of an "epic", the Bible is not one. For one, epics are specifically poems, like the Odyssey.
Dali: "I know what the picture should be ... We take a duck and put some dynamite in its derriere. When the duck explodes, I jump and you take the picture."
Halsman: "Don't forget that we are in America. We will be put in prison if we start exploding ducks."
Dali: "You're right. Let's take some cats and splash them with water."
