But history is already pre destroyed? Roman emperors rewriting there predecessors into monsters, empires spewing nonsense to justify atrocities, the little lies the powerful on all ladder steps of societies tell themselves. Thats why historians have to be such detectives and goto sources who will not lie, like graveyards, drill cores and ancient cesspools. Cause the (re)written word, is almost always of no value when getting to the truth.
