How did early humans use art to express their prehistoric culture? 3rd BlogPost

This is my 3rd blog post, in this blog post Mr. Thomas asked us to answer 1 of 3 questions in a 2-3 paragraph form. The question I chose is in the title of this blog post.
We all have a good idea of what prehistoric humans looked like, something like us, but we don't know what they did everyday, or what they thought about the world. But we do get some hint from the clues they left behind for us to discover. One of the main clues they left behind is what we call cave art. Of course, cave art is, well, found in a cave somewhere. But why did they paint cave art in the first place? Maybe it was just a pass time, or maybe they did it for more, important purposes. We'll never really know because we weren't there.
Cave art is hard to figure out. It could mean, or be anything. The possibilities are endless! They could of known more than us, but, back to the conclusion we weren't there. OK, I haven't really answered the question at the top yet, so here it goes. How did early humans use art to express their prehistoric culture?
I think that they used art to express stories, or legends. I think this because some drawings look like they are only half of the thing itself. Half of a bull could mean the bull was never finished, maybe the bull was waiting for the rest of it's body to be created by some magical being or other animal. Maybe it's just a symbol that means this painting was done by this person. Or maybe they just painted what they saw that day, because they saw a creature that had only have left.The painting could even be telling someone about their greatest adventure, or achievement.
Painting give us a great idea of what life was like back then. There are many cave paintings of animals and what appears to be men with spears. Painting like that give us a hint of what animals lived back then and what they did to survive. Early humans were probably not on the top of the food chain but somewhere there near the top, so to survive they killed for food and safety. Cave paintings also give us hints of their culture because there can be paintings of smaller animals next to bigger versions. This may represent a family. The smaller animal is younger and the bigger animal is older. There's also a hint of their culture in their paintings because some people find paintings that have things in them that are hard to figure out. One time in Humanities we were trying to figure out a picture of a cave painting. The first part was hard to figure out but the last part was even harder. The last part was a picture of some kind of bird, or so it seemed. It looked like a bird, but with very long legs. It still makes me wonder if it was just as it seemed, a bird with long legs, or what other people on our class thought, a totem pole. We still don't know what it is.
In some caves people find, what I like to call, cave prints on the walls. Cave prints are actually hand prints but I like to call them cave prints because their found in caves, and their printed on the wall for eternity. I think cave prints were put on the wall to represent a family, or a important gathering that took place inside that part of the cave. We only have to wonder what they were thinking at the time they painted the walls in the caves. They could've painted, or had a gathering anywhere, but they chose the caves. I'm guessing they chose the caves because they were dry and the safest place at the time. But how do I know that? They could of been the most dangerous places at the time, I wasn't there. No one was, no one but the early humans themselves.
I'd like to thank Mr. Thomas for giving me this assignment, and modthesims.info for the picture of the cave art.
