How did early humans use art to express their prehistoric culture?

I think the art that caveman use is painting and sculpting like the golden clay buffalo sculpture, which is the ceremony of a child transforming into an adult. How scientists know is because there were children's feet was near the statue.  I think that early humans express their feelings about the world, family and religion and how important it is so maybe they decided to paint it so everyone can remember. Looking at these paintings in the past few lessons it looks like they could be telling a story about their heroes or heroines and who brought them one of a important key to survival. I also think that maybe drew some facial expressions and the movement of how character (animal, hunter a tribe) is feelings. 

This connects to their culture by their rituals, like the 'cave painting of a human.' Scientists say that this is maybe a hunting ritual, because social scientist think it could be the artist was asking for success for the other hunters or his self not to be killed and kill the animal. Ceremonies are also a big part because all the art pieces we saw so far are almost all are ceremonies art pieces. Maybe they respect and worship animals because in the paintings I noticed that all the animals are drawn very well and the people are drawn like stick men. I think they respect animals because it is very important to survival even today. If animals do not exist then, early humans did not create the tools we have now and their inteligent then we will not live as long and survive as long as we do now.
