What is the main difference between the era of the Ancient World and the Primitive World?

The era of the Ancient World follows immediately after the time of the Primitive World. In the days of the Ancient World, the construction of cities began. As a result of the unification of these cities, the first states appeared. The primitive world was dominated by the world of primitive communities, which in the new era of the Ancient World changed to a slave-owning system, where religion and the first written language originated. Thus, the era of the Ancient World differs from the era of the Primitive World by the processes of the emergence of civilization – a cultural society.
