This is the first way Indians got food, by going out and getting it. 
The first way Indians got their food was scavenging, they went out, this was before weapons made for the purpose of hunting were created. Most of the time the men took a roll in scavenging, but all the Indians ate back then were dead animals or wild plants/berries.
Scavengers usually did have sorts of weapons such as short daggers but never really started hunting with them until later on; they used these to cut roots and peel dead animals' skins. What happened?
