Before Columbus arrived in the Americas, it was home to many Indigenous peoples and had thriving cultures, cities, and civilizations. This book explains how life was like in the Americas and how the people lived before Columbus changed everything. It also tells the story of how Europeans, when they arrived, thought the Americas and its people were primitive and not as advanced as themselves, when in fact the Americas was quite advanced and had its own unique cultures and peoples.
