Well, in my own personal opinion, I see history as the thing that gives us a purpose. if you look at all the things that humans have that we created with our own hands and minds, whether it be technology, art, or the like, we can attribute that to events that happened thousands of years ago in a place that is far from our own. History is one big "cause and effect". Because history links together, we can draw lines from the now, all the way to something that seems so far from us. This makes us realize why we do the things that we do. It's our purpose to finish history and do the things necessary to keep history going. that's why it's important to know how all of it links together. I hope this made sense.
