I feel like a lot of people in this thread are working with a pretty confused understanding of the word "history". It doesn't describe what actually happened. That's just the past. History is the process of recording the past, of working out narratives and saying to an audience "this is what happened". This is something that we would expect to change over time, and we don't need to sacrifice the view that modern standards are more rigorous, produce more accurate work, and are just generally better, to allow that older work that doesn't live up to those standards is still "history".
