One of the ways to survive that they used was agriculture. Only a few areas in the world actually used agriculture but eventually it started to spread.

These civilizations formed in five different sites. Four of these sights arose along the shores of the great rivers, yet they all formed independently of the others.
As all of these civilizations were arising, there were still more ways to survive needed. A couple of these were hunting and foraging (gathering). There were advantages and disadvantages to this. For example a disadvantage would be that the food supply would often decrease rapidly which would lead to people moving more often. An advantage, however, would be that there was more free time left over after short workdays.
