I have no problem with an approach that treats some of it as real and some of it as allegory or metaphor. It does muddy the discussion somewhat, because it's likely that there will be differences of opinion among Christians regarding at least some parts of the Bible, aside from the ones that insist that all of it happened exactly as written. As long as we're clear where a person stands on any particular story being discussed, I don't see the problem.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
