Prehistory is a period of which we have no written trace. Our understanding of prehistory is constantly changing as we explore and search more deeply for new meanings. We only know what we can dig up and find and because we are constantly finding new objects belonging to the Paleolithic period and the Neolithic period, our knowledge of these eras is constantly evolving. As our technology continues to advance, we are able to form insights into how our ancestors lived and functioned. Everyone looks at events differently and new perspectives are constantly being revealed. So it's important to keep an open mind when dealing with constant deadlines and changes.
