You are just being silly, I can predict the history of the past because it changes to suit the current political power check the history of any tyrannical government. I can't change what really happened but that isn't nearly as relevant as what people think happened. Get a clue.
You are just being stupid. The narrative of the past is not the same as the past itself. The events of the past are fixed and cannot change. It is impossible by definition to predict the past.
The narrative of the past can be changed, and you can attempt to predict those changes in the narrative, which is what I think you are trying to say. But that is not at all the same as the past itself changing.
Ignorance can be cured by learning, in this case by learning what the word “prediction” means, and by realizing that predictions can only be of the future, by definition. If you cannot or will not learn that, then you are, unfortunately, stupid and not merely ignorant.
Get a clue yourself, or don’t; I don’t care. I have wasted more than enough time on you.
