What was man doing for 99%? Of human history?

Thoughts and Reflection;
      During late Paleolithic Era or  The old Stone Age, humans survived by combining  hunting and fishing with the gathering of fruits, berries, grains and root crops that grew in the wild in small groups for a long period of time. Back then people were primitive, even though they were primitive , they were actually very creative. They used stones for weapons, they made sculpture, beads and other forms of jewelry and carved bones and they also painted. People who  created paintings did not write, and historians can't be certain of the reasons for this surge in artistic expression Itself. After thousands and thousands of years they started using symbolic language that changes their life style.
