Humans have lived in what is now
Niger from the earliest times. 2 to 3.5 million-year-old
Australopithecus bahrelghazali remains have been found in neighboring
Chad.
Archeologists in Niger have much work to do, with little known of the prehistory of the societies that inhabited the south, the home of the vast majority of modern Nigeriens.
[1] The deserts and the mountains of the north, though, have garnered attention for the ancient abandoned cities and pre-historic rock carvings found in the
Aïr Mountains and the
Ténéré desert.
Considerable evidence indicates that about 60,000 years ago, humans inhabited what has since become the desolate
Sahara Desert of northern Niger. Later, on what was then huge fertile grasslands, from at least 7,000 BCE there was pastoralism, herding of sheep and goats, large settlements and pottery. Cattle were introduced to the Central Sahara (
Ahaggar) from 4,000 to 3,500 BCE. Remarkable rock paintings, many found in the Aïr Mountains, dated 3,500 to 2,500 BCE, portray vegetation and animal presence rather different from modern expectations.

One recent find suggests what is now the Sahara of northeast Niger was home to a succession of
Holocene era societies. One Saharan site illustrated how sedentary hunter-fisher-gatherers lived at the edge of shallow lakes around 7700–6200 BCE, but disappeared during a period of extreme drought that may have lasted for a
millennium over 6200–5200 BCE. Several former northern villages and archaeological sites date from the
Green Sahara period of 7500-7000 to 3500-3000
BCE.
[3] When the climate returned to savanna grasslands—wetter than today's climate—and lakes reappeared in what is the modern
Ténére desert, a population practicing hunting, fishing, and cattle husbandry. This last population survived until almost historical times, from 5200–2500 BCE, when the current arid period began.
[4]
As the Sahara dried after 2000 BCE, the north of Niger became the desert it is today, with settlements and trade routes clinging to the Air in the north, the
Kaouar and shore of
Lake Chad in the west, and (apart for a scattering of oases) most people living along what is now the southern border with
Nigeria and the southwest of the country.

my brehs...I knew 'common sense' would reign supreme. Great work still Tommy Knocks very much appreciated.
The north europeans didn't know how to read or write until the Romans taught them (1AD), and Greece was europes first civilization (300BC) with the help of semite neighboring countries who obtained their knowledge from the egyptians. Egypt and Nubia had already been rolling since 3,000BC
The Hominini divergence happened 7 million years ago meaning we just had older versions of humans chilling around the world gaining consciousness and taking baby steps to civilization
