Hogwarts and the Bible?? Not the same by distinction or content. In fact opposite of each other. Hogwarts does not give the history of Israel past present and future or speak of a mighty nation that comes to the aid of their brother, the house of Judah in the last days, having its tall images knocked down and cities destroyed. History speaks of Jesus and the Bible that survived under God's protection, being written by men from different centuries and all kinds of backgrounds, from kings to shepherds, yet sounding like one author in agreement of man's condition of sin and death and the need for a Savior. That author being the very Spirit of God, Himself, inspiring men after His own will to write of Him. Check out the evidence of the Bible just in age and number of manuscripts available. In comparison, Roman history would be a myth. There is just no book like it on the face of the earth, and it has evidence that demands upon us a verdict. It t least deserves more than a glance, IMO, but that does not mean there are not many other things out there to demand our attention and wants for amusement...
It's a big mistake to ignore it and compare it to a book of sorcery, which the Bible condemns, as there is a devil and his demons, the third of the angels that fell from God's realm in rebellion, that manifest themselves through the works of men, but only if allowed - usually by deception. Ofcourse, evil can be denied to, even though its works in the world are easily seen, but that's a whole different subject.
I can see that you have not read the Bible very closely or with interest, not that it does anyone good that would do so without a seeking heart and unbiased mind. To narrow the mind to just what can be seen has always been that thing which kept man from moving forward whether in science or in spirituality. All things are made of the unseen and all things are possible. It is only in the restrictions of our minds and our ignorance that the unknown is not revealed, and even that which can be known and seen can be ignored for what it must truly represent. All creation speaks of God. Even our conscious being spoke of God at some time in life and knew Him as Creator, but that truth is easily displaced with lies and lawlessness in this world of peril - where sin and death rule if not for God's promise of eternal life.
