What were Canada and America like before they were colonized? Are they all aborigines?

Before the American colonial period (1607)

More than 20,000 years ago, a group of vagrants from Asia came to Central and South America through North America. These people are the ancestors of Indians. When Columbus discovered the New World, there were about 20 million Indians living in America, of whom about 1 10,000 lived in today's Canada and north-central America, and most of the rest lived in today's Mexico and South America. About 1 10,000 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. They are a group of adventurous fishermen. Some people think that they went to the east coast of North America 1 0,000 years ago.

Indians and Inuit (Eskimos) were the earliest inhabitants of Canada.
