The rest of Europe was not as advanced. The Jews in Spain were, for the most part, the greater part of the industrial sector in the Mediterranean or Europe. The Spanish kicked them out.
Were you trying to tell us that the settled agricultural tribes in the Americas were not as smart as the Spaniards?
Cortes, for example, was not fighting against hunter/gatherers. His enemy had command of just about the largest city in the world at the time.
And they were so sophisticated that they smote the evil Spaniards back across the ocean from whence they came. You're getting revisionist garbage from left-wing profs.
