Would not that be the very definition of "faith"? Keep in mind that these "stories" can't be DISPROVEN either.
As I mentioned in another topic, I am pagan, and personally believe the "gods" may be highly evolved aliens. Can't be proven, can't be disproven.
As for any holy books or religious works (even the Edda of my own beliefs), they must be taken with a grain (or more) of salt. Ultimately they were all written by men and subject to error and personal bias.
I suggest you read "The God Delusion" by Richard Dawkins. Of course, he is what you might call an "evangelical athiest", so keep that salt handy. Pay particular attention to "the invisible teapot" illustration, which kind of highlights the can't be proven/disproven thing.
