What is the prehistory of America?

1497, Columbus, a magnificent wave of North American immigrants, "mistakenly" discovered America, a virgin land far from human civilization. This brilliant "mistake" began the history of a country threatening the world today. In order to stick to their beliefs, groups of Protestants came to the United States to expand their living space. In order to escape from the demons of death and hunger, poor farmers and craftsmen also moved to America. The enclosure movement in Britain forced farmers to lose their land and be displaced, and many people joined the ranks of immigrants. Colonists and explorers hoped to find gold in this strange land. As a result, a magnificent wave of North American immigrants lasted for hundreds of years and became the "prehistoric era" of the United States.
