Can you offer any proof - besides 2000yr+ old testimony - that:
* Hammurabi compiled a systematic code of law;
* A real man named Socrates inspired generations of Greek thinkers;
* Plato wrote a book named "The Republic" which expressed his dualistic philosophy;
* A young general known as Alexander conquered vast portions of the known world;
* Emporor Caligula grew into a cruel and demented individual;
If the historical record is not enough to prove this fact, then the entire breadth of history is meaningless drivel.
