It is based on the fact that all the oldest hominid fossils have been found in Africa. As a result of that the theory goes that human life originated in Africa.
Early humans are believed to have originated in Africa. The earliest known hominids, such as Australopithecus afarensis and Homo habilis, have been found in various parts of Africa, supporting the theory that this is where human evolution began.
Africa
It is argued that the human race began in Africa, therefore Africa is the cradle of civilisation.
The theory is that human language originated in Africa, particularly in the regions of eastern and southern Africa. This hypothesis is based on genetic and linguistic evidence, as well as archaeological findings.
It is the theory that the origins of our human species were located in the Rift Valley of east Africa, and that humans first began to make their way (migration) out of Africa approximately 100,000 years ago. As such, all of our ancestors were originally from Africa. The first migration was to the Middle East, then slowly beyond. The last areas to be populated by humans were North and South America, with the first humans having trekked across the "land bridge" during the last Ice Age, about 11,000 to 15,000 years ago.
Because that is where human bones were first found.
Assimilation model, multiregional continuity model, and out of Africa model
Some theories of human evolution include the Out of Africa theory, which suggests that modern humans evolved in Africa and migrated to other parts of the world. The Multiregional theory suggests that modern humans evolved simultaneously in different regions of the world. The Recent African Origin theory posits that modern humans originated in Africa and replaced other hominid populations.
I guess you could say the God was the founder, or creator of Africa. Humans were created in Africa, so they didn't even 'discover' Africa.
Africa is widely referred to as the cradle of human civilization. It is the birthplace of early human ancestors and played a significant role in the evolution of the modern human species. Archaeological and fossil evidence support the theory that humans originated in Africa before spreading to other parts of the world.
The continent of Africa is believed to have been settled first by early human ancestors. Archaeological evidence suggests that human ancestors began to populate Africa around 2 million years ago.
