1). Cave drawings

Cave drawings were the first evidence of people, along with this they are also the first images done by people. They were used as a marker by cave men to say, “I was here” (like modern graffiti where people write there names on walls). Silhouette images of hands, done by cave men, were also used similar methods used today. Cave men would spray the paint from their mouths to get the shape of the hand, kind of like spay paints and templates used today.
