History lessons should include material that relates to the Bible.
This is important because people/students should have an understanding of how the church has tried to re-write history down the ages. This should be especially true of the methods that the church has employed to re-write history. Methods such as: torture, burning people alive at the stake, assassination, mass murder, genocide, war, book burning, the destruction of evidence, destroying the holy shrines of older religions and building churches on the same sites, mass indoctrination and plagiarizing the myths of other cultures.
Religion has aways sought to distort the truth and bury the reality. This should be taught in schools.
