When did the nomads come to north America?

Answer 1

The first nomadic hunters walked across dry land from Asia. The great ice age lowered the water of the Bering strait and created a new land, Beringia. Beringia is generally thought to have been a flat plain, dry and dusty. It did support plant and animal life. The date they arrived is in dispute and keeps being pushed back. The land bridge existed between 10,000 and 25,000 yeas ago. Supposedly the way south wasn't open much before 12,000 years ago. At the same time sites in Virginia, Pennsylvania, and Chile have been dated to 16,500 years ago. Current thought is that people were in Alaska at least 18-22,000 years ago and found a way South.

Answer 2

Nomads are people that are constantly moving from one place to another. The first nomads to travel to North America lived during the Ice Age.
