What we understand when we talk about prehistory is the period of time elapsed during the evolution of early hominid ancestors of modern Homo Sapiens until the appearance of the first written records that humans wrote on Earth. So it is the period of time in which humanity was only able to pass on their knowledge from generation to generation orally. The historical sources that we can analyse to study Prehistory are only prehistoric archaeological sources as there are no written sources. In addition when we study the prehistory we find that the preserved archaeological remains are scarce and are actually only a small percentage of objects that existed.<br />

Prehistory is usually divided into the following stages:
* [[Paleolithic|The Paleolithic]] is the oldest and longest stage. Men were nomads and were engaged in gathering and hunting. They had to adapt to [[climate changes during the Paleolithic | several important changes to the climate]]
The Mesolithic |Mesolithic]] is the transition between [[ The Palaeolithic in the Quaternary and Pleistocene |the Paleolithic]] and [[Neolithic]] between 10,000 BC and 7,000 BC Mankind still engaged in hunting and gathering but the last ice age has ended.* [[ The Neolithic |Neolithic]] agriculture and grazing appears and begins to form the first permanent settlements.
