The left alway pushes revisionist American History in publics schools. Obama went on the apology tour blaming the USA for all the troubles of the world, while ignoring the impact of dictators ad socialist atrocities. This was consistent with left wing education.
The left is very insecure, since their propaganda is metastable, and will not take much to knock over, if the students start to discuss alternate ideas. Currently, the left has a monopoly when it comes to forced indoctrination via testing where students have to repeat the lie to get a good test score. They fear others will use testing to force a competing indoctrination.
The main cause of revisionist history, in public schools, is due to the left based educational system, trying to throw all demographics a bone, in terms of teaching history; added more in terms of the role of women and minorities to the lessons. Since the time for teaching is limited, this often misrepresents history, in terms of the impact of the major things, needed to get a proper vision of the overall past.
As a loose example, say a new club is formed. This club was conceived and forms due to the efforts of two members, who were the funding parents. It now has hundred of members. In an attempt to make it "fair", the left will try to add the contributions of anyone, with an alternate demographic; their voter base. Since there is only an hour to teach this history lesson, this added data alters the historical perception, since it does not do justice to the biggest contributions of the two founders, in short time available. History is distorted and revised based on political priority, under the guise of fairness.
The left teaches America from the eyes of the contemporary PC standards, instead of maintaining history in the context of its own time, where people have limited understanding of future times, just as we do. Make America Great does not resonate with those who have learned revisionist history.
The way I look at Creation, is this is connected to the evolution of the human mind. It is not about biology, which is a revisionist history trick to sabotage it. The timing of Genesis; science based carbon dating, coincides with the formation of the first stable civilizations.
Civilization was not based on instinct and DNA. There is no civilization gene. It was based on a profound change in the human mind. Civilization was contradictory to eons of natural evolution based on humans who were wanderers, hunters and gatherers. Staying in one place, to form civilization, while expanding population was not natural. These first civilization humans needed a new mind set, that could willfully chose to ignore eons of instincts and fight the urge to wander.
This was the divine spark that the mythology of Creation teaches. DNA tells us nothing of this psychology change. DNA is only good for superficial things like hair or skin color. Fossils can tell us about their possessions, skills and things, but It cannot tell us what was inside their minds. There is a tendency for science to use revisionist history, to infer the mind set of the past, by the present. The bible, on he other hand, is a record of the mind from that time. It is more like a raw data set of mind data, in terms of what the first "new" people believed. It is part of real history.
