Another reason is that about other artifacts about sculptures, etc, it shows how creative early humans were. For the sculptures, the hominids used different tools such as a rock, etc. Not only that, but hominids also made and dug traps for small animals. The hominids are good hunters using spear throwers, stones, etc. Hunting is a big thing for hominids because they could chase horses, bisons, and get the meat and the skin for survival. When hominids found shelter, they started to express their feelings about the world in art and they started to make sculptures.
So artifacts can tell us about the lives of early humans many ways by art, etc. "These artifacts and the blessing they bring are for all the people. This is such a rare opportunity-probably never again in my life time," by archaeologist Noel Lee. Without these artifacts, we wouldn't have a clue of about the lives of early humans.
This is the other part of the cave painting.
These are some sculptures of bisons that were made about 14,000 years ago.
