I will start lightly with how the history that we were taught in school was not based on history.
I have always been amazed with the history books crediting Christopher Columbus for “discovering America”, at a time when Leifr Eiriksson’s heirs were hundreds of miles inland. Remember Columbus was not looking for America; he was looking for a short cut to the Far East to bring back goods. When he got to America, he did not know where he was! When he went back to Europe, he lied about where he had been. And this is the great explorer, who discovered America!
