Most of what people are taught about human history is full of half truths and complete lies. The subject of who created the printing press is just one of many examples. Government approved education is not meant for educating people to think critically and be their own person, but to worship government and authority. Unlearn what they have taught you and don’t trust it. Home schooling, private education and self education resources online are the best ways to get educated and to pass down your values to your children and/students.
