I'm not a Christian and I'm hesitant to challenge you on Christian theology, but since when do Christians believe that every single word of Jesus' was literally true? I was under the impression he was famous for speaking in parables.
"I was under the impression he was famous for speaking in parables."
He did indeed. But in most cases it is made clear by the author that Jesus was using a parable.
Almost always, an introductory phrase such as, "Another parable put he forth unto them, saying, The kingdom of heaven is likened unto..." to distinguish a parable.
On the other hand, Jesus claimed to have been an eye witness - to have actually been present when Lucifer was cast out of heaven. This would be before the creation of man. This implies a lot about Jesus' knowlege of the facts of creation.
