That is a good question, and you would be surprised to see the advanced richness of Native American civilizations that existed prior to European contact (1492).
For example, the Mayans, Aztecs, and Incas in Mesoamerica (Central to South America) built great empires that were advanced far beyond our perception of stone age savages. Like the Egyptians, they were astronomers and architects who did complex calculations with a unique counting system. They built great pyramids, and they had their own calendar. The resources were so plentiful that their civilizations grew to an estimate of 19 million! Sadly, we do not have their original written records because the Spanish Conquistadors destroyed almost all of them under the belief that they were pagans who needed to be converted to Christianity. In fact, these beautiful civilizations were completely destroyed by the Conquistadors.
Another Native American civilization were the Anasazi, also called the Ancient Pueblo Peoples. They were located in the Southwestern corner of North America, which is around Arizona, New Mexico and Mexico. They were also astronomers, architects, and farmers. As architects, they built great pueblo housing complexes to support large populations. As farmers they build vast irrigation systems for their crops. Unfortunately, their population grew so large that they overused their land, and, to make matters worse, a 300-year drought led to the eventual collapse of their civilization.
I hope this will encourage you to read more about the Native American Peoples. You will learn that they were far more advanced than you would ever imagine.

Most of the Native Americans whole civilization revolved around the mighty buffalo because it could provide food, shelter, and bone tools and weapons.
To Native Americans, no one owned the land- it was there for everyone else to use. Native Americans saw land treaties with Europeans as agreements in which they received gifts, such as blankets, guns, iron tools, or ornaments, in return for which they agreed to share the land for limited time.

Many tools were made from nine and stone, but as was their nature, Native Americans used every part of the animals they killed including the tendons, bladder, etc. It depends upon what tools you are referring to.

Mainly planting. The Native Americans never really were big on using tools. That was considered a "White Man" tradition.
The Native Americans of the "Plains" made "Tepees, Whips, Clothes, and other items such as tools and Drums" [ETC]
Some tools developed in the Middle Stone Age include blades, scrapers, burins, and microliths. These tools were typically made from flint, obsidian, or other types of stone, and were used for activities like hunting, skinning animals, woodworking, and cutting plants. This period saw advancements in tool technology and the development of more specialized tools for different tasks.
