Prehistory of mankind is way too horrible to be remembered.
But if we choose to ignore it, then we'll be doomed to repeat it.

One of many reasons why some people today are very difficult to accept the existence of advanced technology in prehistory era is because they didn't realize that their minds have already been clouded by an unconscious presumption which states 'ancient people should be primitive, before gradually evolving into this modern era nowadays'. I call this as 'Toba Syndrome'.

Ignorance is a knowledge illiteracy.

If the ruler of this world really believes that earth's history repeats itself again and again, then I understand why the truth about prehuman civilizations are kept secret so tight.

In this life, when you deny someone an apology, you will remember it at time you beg forgiveness.

Often blaming, is a trait of a childish soul.
