You will likely have a better time getting an answer the more specific you can be with your question: do you want to know about Native Americans on the East Coast of the modern US? The midwest? California? Arctic Circle? The Aztecs?

That being said, here is a BIG related overview Native Americans in what is now the USA have often been portrayed as having "idyllic" lives before Western colonizers arrived - is there any truth to this? How much "easier" were their daily lives? Before Western diseases and colonists arrived, was it a life of easy hunting and simple living? written by u/Snapshot52 and others. I think you might be interested in this comment written by u/retarredroof which is a bit more microfocused.
