Why the Spaniards didn't leave the land of the INCAS?

Unlike Asia and Africa, America never saw their invaders leave. Their autonomy was lost, but that does not mean they have disappeared. Many survived, specially the ones who still lives in the cordillera and valleys around.
In the Andes, more than 12 million people still speak the language of the Incas. For five centuries we have listened only to the history of the "winners".  It is time to hear the other side of the story that began in 1492 and still continues to this day.
America as a continent was not discovered because by logical thinking you cannot discover an inhabited land. Instead we can say it was invaded. Such an obvious point has been distorted by the history that Europeans wrote and taught to the world that was totally in chaos and in need of fairy stories or myths.
The history of the other side is also mythical, but while Western myths are triumphalist, those of the 'less fortunates' have to explain and overcome catastrophic scenarios.
Education about the world to the generations of the 1950s and 1960s was something that happened mainly in Britain before 1850s. A little of Greece and Rome, and a great deal of the Tudors, Stuarts and Hanoverians was the drummed history of the time. Nothing about the Incas of Peru and other cultures of Central America. They were dismissed by Western historiography.
Ancient America was shown as poor and undeveloped continent, laking the progress that the humans in the other side of the world had. The plow and the wheel were their favorites; another was writing. Historians took the absence of them as proof that ancient Americans weren't civilized. It never occurred to them that plows and wheels are not much use without draft animals such as oxen or horses, neither of which existed in the Americas.
Ancient Americans developed magnificent achievements in fields that are now being of great interest to astronomers and mathematicians.
We can see from this perspective that the Europeans felt diminished by the outstanding achievements that this people did without the commodities of the West.  They did not tell to the western world the real story about this great civilization instead they meddled the cultures hoping in the end to reach the knowledge that these Andean People had. But one important they forgot, these Andean People were not cut for the pleasures of the western lifestyle, instead they were formed and dressed to fight for the rights of the Cosmic Force of the Creation and to maintain the harmony of these force in every living being around the Cordillera of the Andes.
