Superman, was a commerical venture by a company that never claimed that Superman was real. Nor do millions of people pray to Superman, nor has anyone ever seen a miracle by Superman.
Try harder next time.
I can write a story about a Marshmellow God, but to have facts in history to back it up? No I can not. However, the story of the bible has many historical facts in it. And as far as I know no one has ever disproved the bible.
I can disprove Superman. I can contact the authors, finf the orginal scripts and drawings and ideas. Can you do the same for the Bible? Yes, look outside at flowers, animals, life, and yes death.
