Why did the growth of civilization make government necessary

They needed control and land laws and farming laws, also currency

As a civilization develops, government is needed to balance any decisions, religion, and/or way of life. Without a central government, a civilization is most likely split into separate groups to survive, whereas with a government everyone can work and fight together. I hope this helps :D
