Early civilization:

More than 40 thousand years ago, Indian ancestors arrived in North America through Asia, and then to Central America and South America; When Columbus arrived in what he thought was the New World, about 30 million Indians lived in America. Today, about 654.38+50 million Indians live in the United States and Canada. The composition of these indigenous people is very different in heredity, language and society.

It is estimated that in the15th century, there were at least 400 unrelated and distinctive cultural forms in the north of the Rio Grande, with various body types and language families.

About 10 thousand years ago, another group of Asians moved to northern North America, which became the Eskimos. The first white people to come to America may be vikings. Some people think that they went to the east coast of North America before 1000 years ago.
