You don't accept my valid argument from history. You don't accept miracles either. There's nothing you would accept, it seems. Even if a miracle happened before your eyes, you can always devise alternate explanations.
Of course Christianity requires faith, but so does believing in the existence of Abraham Lincoln. I never saw Abe myself, but I have faith based on the historical records, eye witnesses, and in what he has done.
Faith can either be evidence-based or blind or delusional. We have to use our brains.
If I grew up in ancient Greece, maybe I would have argued with conviction for Zeus. That changes nothing. But here is the big difference: I would not have any good evidence for it, but I do have plenty for Christianity.
I repeat myself when I say that just because people believe in false gods, or that people may believe in their god because of their culture, it does not follow that there is not a one true God -- or that one can confidently know the true God based on historic and other evidence.
