Archaeologists try to find out about people of the past from which no written records exist.
Rock art is only one field of research for archaeologists. However, archaeologists have certain problems with the art because it is different from the other material which they study.

By studying this material archaeologists hope to find out how it came there and what it reveals about the original people who used these objects. This process does not work with rock art.
