History is about the past. One must be mindful that rehashing the past means the information is static, and can be (and usually is) filtered. Humans detail the past through stories, typically in the form of image, video and words. Even if the story told is with perfect honesty, it represents a source of communication (information transmission) error on several notable fronts: (i) perceived and expressed through the point of view of the author/s; (ii) closed loop of space and time within which the story takes place; and (iii) difficulty in defining and communicating qualia. There was a stream of information, some of it more consequential than others, that led into the circumstances painted in the story, and there was a stream of information that came out of the story. It is (seemingly) impossible for a human to perceive, let alone detail, this information flow into a finite storyline. The best we can settle for are approximations of what "happened", of what led to that happening, and what came after. The better the explanation, and harder it is to vary, the more reliable the story of history.
