I agree that Harry Potter is fictional and that some of the Bible relates to historical figures. But any narrative is embellished and changed over time. The four accounts of Jesus' life in the New Testament don't agree on events. Archaeological finds don't vindicate things in the Bible, it's too easy to find an old artefact and conveniently match it to something written thousands of years ago. And thanks, I have an education, in physics, which is why I can point to lots of scientific findings.
The human hand print... someone put their hand in some mud, and then that impression was covered in more mud and then by a global flood, yet the hand print was preserved? Yeah, right...
