Eastern Sahara has been an interesting study object for the specialists who search for the history of this place. There were assumptions about an important pluvial event that could have happened between 6500 and 2500 years BC. These assumptions were confirmed by some fossils from a lake sediments dating from the Holocene epoch that were discovered recently. What today are hyper arid area with no plants, once were regions of desert grassland and savanna. In the Sudan's North-West were found about 500 kilometers of vegetation from the Holocene period. There were analyzed the salient features from the Southern and Northern sites that were discovered as well as the pollen of these sites in order to show that in the Eastern Sahara existed a gradient cover with vegetation. The fact that in its prehistoric times, the Eastern Sahara had water resources from the rainfalls or from rivers was shown by some researches that were made regarding the Sahara wet condition in the prehistoric times. The data revealed the existence of three dry river courses with a width that varies from 8 to 20 kilometers. The existence of the water sources in the prehistoric Sahara allowed to the man, animals and plants to exist in the Eastern Sahara of those times. The existence of these dry river courses also explains the oases` presence in such a hyper arid zone. The origins of these rivers are in the Sahel's sub-Saharan belt or the Sahara's massifs. It seems that the last time when these rivers were flowed with water was during the pluvial event we were talking about in the beginning of this article. Life and death in the Eastern Sahara were brought by the alternation of the wet periods with the dry periods, as well as the fauna and flora`s modifications.
