-because thats where humans evolved
The development of humans that walk upright and opposable thumbs. It helped scientists classify us as modern humans.
There is no completely accurate record of ancient history. Anywhere. Ever. Anything written by humans will always be subject to human biases. Also, ancient history is a very broad term, and no one book talks about all of ancient history. For parts of "ancient history", humans did not even have complex (key word being complex) spoken language, and certainly not written language.
Early human history is divided based on how early humans made their tools and weapons. These ages are The stone age, the bronze age and the iron age.
The name of the person who invented the first knife is lost to history. People were using sharpened animal bones and rocks as knives long before humans had learned how to write.
Africa
The letter A represents Africa, where it is believed that the earliest humans lived based on archaeological and anthropological evidence.
Oldest bones unearthed.
The earliest traces of humans on Earth date back to about 2.8 million years ago, with the discovery of hominin fossils in Ethiopia being some of the earliest evidence of human ancestors. These early hominins were part of the genus Australopithecus, such as "Lucy" (Australopithecus afarensis), and represent our early evolutionary history.
Great Rift Valley
Many are awaiting the time when Sara Palin leave Alaska so there can still be humans present there.
The earliest modern humans, Homo sapiens sapiens, are believed to have appeared around 300,000 years ago in Africa. This is based on fossil and genetic evidence.
The earliest humans are believed to have originated in Africa, as supported by fossil and genetic evidence. This is commonly referred to as the "Out of Africa" theory, which suggests that modern humans first evolved on the African continent before migrating to other parts of the world.

To date, fossil evidence shows that humans existed in the Western Hemisphere as far back as 10,000 BC BCE. There is also evidence of tools that also match the fossil remains.
