Prehistoric Art
When we visit art galleries or learn about art in school, we tend to think of paintings on canvas, sculpture or photographs. Often these will be clearly recognisable as people or objects like food and flowers, and we can relate to them as familiar in some way.
Art and pictures have been around ever since people first were recognised as human by historians, in pre-historic times. Prehistoric simply means history which dates before written accounts are available to study. The earliest humans did not have writing with which they could communicate and this means that art and pictures were even more important to them.

It had land, an extensive atmosphere and an ocean that covered two thirds of the northern hemisphere as well as smaller bodies of water. But significant climate change caused the water and atmosphere to boil away, leaving Mars a dry and arid planet. Or so we thought… then came the news from Nasa – Water found on Mars!
