Name them. Gather their testimony. I will wait.
***Name any other figure in history that meets this standard you have set up. I will wait. You throw out Hammurabi, David, Moses, Julius Caesar, Columbus, even George Washington with such an impossibly anti-scientific historical standard.

Pontius Pilate did leave behind a stone carving with his name and title. That appears to be more than the contemporary evidence of Jesus that is available to us.
