Please I need some help with this

The history of Greece can be traced back to Stone Age hunters. Later came early farmers and thecivilizations of the Minoan and Mycenaean kings. This was followed by a period of wars and invasions, known as the Dark Ages. In about 1100 BC, a people called the Dorians invaded from the north and spread down the west coast. In the period from 500-336 BC Greece was divided into small city states, each of which consisted of a city and its surrounding countryside.
There were only a few historians in the time of Ancient Greece. Three major ancient historians, were able to record their time of Ancient Greek history, that include Herodotus, known as the 'Father of History' who travelled to many ancient historic sites at the time, Thucydides and Xenophon.
Most other forms of History knowledge and accountability of the ancient Greeks we know is because of temples, sculpture, pottery, artefacts and other archaeological findings.
