Native Americans have inhabited North America for thousands of years. Before any other civilizations came to embark on the United States, Native American tribes had flourished throughout the land. Starting from the Archaic Period, they had created a way of life  like no other; Native Americans created tools and shelter using what they found in nature, and hunted nearby animals for food and clothes. From creating spear points with rocks to hunt for food to using stone pestles to grind medicines, Native Americans lived a life that was constantly advancing.
