HEY MATE HERE IS YOUR ANSWER -

In paleoanthropology, the recent African origin of modern humans, also called the "Out of Africa" theory (OOA), recent single-origin hypothesis (RSOH), replacement hypothesis, or recent African origin model (RAO), is the dominant model of the geographic origin and early migration of anatomically modern humans (Homo sapiens). It follows the early expansions of hominins out of Africa, accomplished by Homo erectus and then Homo neanderthalensis.

Expansion of early modern humans from Africa through the Near EastMap of the migration of modern humans out of Africa, based on mitochondrial DNA. Colored rings indicate thousand years before present.The model proposes a "single origin" of Homo sapiens in the taxonomic sense, precluding parallel evolution of traits considered anatomically modern in other regions,but not precluding multiple admixture between H. sapiens and archaic humans in Europe and Asia.note - H. sapiens most likely developed in the Horn of Africa between 300,000 and 200,000 years ago.The "recent African origin" model proposes that all modern non-African populations are substantially descended from populations of H. sapiens that left Africa after that time

Note - H.Sapiens means Homo Sapiens , the early humans
