All this started just with excess/surplus of food. It has led to the start of a basic civilization, which now has been changed/modified by people to create a more productive environment and world around them. It shows us how creative humans were; with so little, they have come to so much. Even now, civilisations are being modified and can tell us so much about a certain place. With so little, we can make so much and lead a much better world. If we did not have civilisations, we would still be hunter gatherers, searching for food and keep moving. A civilization helps us settle down somewhere.
