 Well, there's no such thing as miracles. Therefore, Jesus prophesied the destruction of Jerusalem. There's no such thing as prophecy. Therefore, the Gospels could not have been written before the destruction of Jerusalem. Well, guess what? Luke and Acts very clearly were written before the destruction of Jerusalem. They don't talk about the destruction of Jerusalem. They don't talk about the trial of Paul, which would have been probably around 64 AD. So Luke and Acts were written before.
