The cradles of Civilizations
Though all cradles did not fructify into large cities yet the effort was made by humans at various places.
The cities, as we know, came into being only 5000 years back i.e. around 3000 BCE, as far as our discovery of ancient cities is so far made. Small settlements with or without buried corpses of earlier time period show that human civilization existed for far longer period and only thereafter developed enough technology to build big cities.
Small settlements are mostly from stone age and the cities show signs of metallurgical knowledge which was called as copper age. The places where human settlements of stone age were found are called cradles of civilisation for here human civilisation was in nascent stage from which it grew up later to adolescence age or copper age.
It may be noted that there are 84 ancient settlements of civilisations are listed in Encyclopedia Britannica. These are:
