You also have to keep in mind that these stories, whether they were transmitted written or orally, they're oftentimes retransmitted from generation to generation. And especially in the oral case, but even in the written, you gotta wonder what's added over each generation. You can imagine people embellishing, making the story a little bit better, or taking out things of the story that really doesn't fit in with their worldview. So even when we have the writing, and this is, once again, some images of early writing. This is the famous Sumerian cuneiform, this is a Sumerian cuneiform tablet here. Even when we have it, and obviously we have much, much more writing as we get to the more recent past, we have to be very, very, very skeptical. We know today, even if two observers observed something yesterday, something that just happened, they might have very, very different perceptions of what happened.
