Why do People Make Art?

I think that people way back in the beg. of time decided to draw stuff and create art because they wanted to remember something they saw in the day or if they had like a dream or something then they wanted to record what they saw they would draw it instead of writing it because a lot of people didn't know how to write. Now a days, I think that people decide to make art to pretty much do the same exact thing. Artists want to take an image that can change over time and capture it in the moment when they see it. Also art is made to show an artist point of view on something. Overall, I think the purpose of creating art hasn't changed at all.
