During this time of “prehistory,” humans spent most of their lives moving from place to place, hunting for food, building crude shelters,protecting themselves from wild animals and from the wrath of nature. Around 3000 BCE, things slowly began to change. For the first time, humans started to settle down in one place.

Easy access to a river or a sea was important because people need it for food (fishing) or irrigation, transportation and trade.
