Is Luke Skywalker a Real Person?

I'm not at all convinced that you can infer from the fact that Jesus said that, that he believed in a global flood. And that event really happened. We know he's not omniscient because he says that he doesn't know stuff. He pleads ignorance about certain things. Supposing you could show that Jesus believed in aglobal flood then you have, I think, a difficult question about when God became incarnate in Jesus.
