Mujus, the "we" is collective (based on that used in Gobbledygook's post). I think the major problem with the Bible and similar texts is that supernatural/otherworldly phenomena are described alongside comparatively mundane phenomena. You're right that because of that, these texts tend to be discounted as evidence, but I think part of the reason for that is because it's difficult to determine what they are, if accepted as such, evidence for, whether that's the existence of a given deity or a collection of deities or whether that's the occurrence of a natural disaster or other event (such as a global flood), or if one is supposed to be evidence of the other, or vice-versa. I always find it interesting how some people tend to think that an original document is automatically more accurate than later versions based on its original status, when the possibility exists that the originals are the most flawed versions of a given document, and that later versions come into existence in order to rectify those flaws. Of course, in some cases, such as in Adolf Hitler's Mein Kampf, for lack of a more contemporary example (and the fact that the validity of religious texts is subject to a greater degree of debate in comparison, but I digress), later versions can add to those flaws and thereby damage the work's reputation in a fashion that would not otherwise occur. Please excuse my mangled train of thought, though it could just be me rambling, as I tend to do on occasion, for the same reasons.
