Sumerians invented writing around 3100 BCE. They used it for the accounting system of the goods that were traded at Uruk. The writing consisted of pictographs, simple pictures that explained what the situation would be. It is like representation of something that you would do. The symbols evolved from pictures to phonograms and later became true writing system.
Even in today's world, we, in everyday life use the pictographs for almost everything. For example, when we are driving we follow the directions of the pictures that represent situation or motion that we want to do. Like “plane for airports”, “ bench for picnic area or rest area”. Essentially, we are following the same approach as they did.
