Yeah there is. Objectively, the recording or telling of any historical event in any language in probably all times, has been laced with allegory, rhetoric, bias and comment. Literature is by nature whether it be historical, scientific or fictional ~ imaginative, embellished, encoded and colloquial.

So how to tell which parts to view in an allegorical sense is easy. All of it. It's all in some way analogously but not literally related to our present world, written by thinking people of an ancient world.

Consider, if someone was to find the writings on this site in a couple of millennia and read through them to find discontinuity between your thoughts and the thoughts of one of your fellow atheists and come to the conclusion that you, neither, based anything you had to say in real experience because you contradicted each other, what would you have to say to them? There is your answer.

I'm sure in a couple thousand years people will say the same about the limits of our knowledge. But you'd still hope that our better half of wisdom could stand the test of time, right?
