Here's something about humans.

Here are some important events in human history:
Homo sapiens
Around 315,000 years ago, Homo sapiens first appeared in Morocco

Neolithic Revolution
Around 12,000 years ago, the Neolithic Revolution in West Asia led to the domestication of plants and animals, and the transition from nomadic to sedentary life

Iron Age
Around 1,300–900 BC, the Iron Age began with the discovery of ways to heat and forge iron

First written records
Around 3,200 years ago, the first written records in Old Chinese were recorded on oracle bones

Mycenaean Greece
Around 3,450 years ago, Europe's first deciphered writing was discovered in Mycenaean Greece

Maya script
Around 2,300 years ago, the Maya script, the only known full writing system developed in the Americas, emerged

Middle Indo-Aryan
Around 2,260 years ago, the earliest deciphered written records in South Asia were discovered

Human history can be divided into several eras, including:
Stone Age: 3.3 million to 5,000 years ago
Bronze Age: 5,000 to 1,400 years ago
Iron Age: 1,200 BC to 500 BC
Classical Era: 500 BC to 500 AD
Medieval Era: 500 AD to 1500 AD
Early Modern Era: 1500 AD to 1800 AD
Modern Era: 1800 AD to present

Added information!

The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago.

First know appearance of humans.

Humans first appeared in Africa between 6 and 2 million years ago. The species that humans belong to, Homo sapiens, evolved in Africa around 300,000 years ago.

Here are some key milestones in human evolution:
300,000 years ago: Bones of primitive Homo sapiens first appear in Africa.

200,000 years ago: Anatomically modern Homo sapiens appear.

100,000 years ago: Brain shape becomes essentially modern.

50,000 years ago: Humans develop the capacity for language.

70,000-100,000 years ago: The first modern humans begin moving outside of Africa.

12,000 years ago: The beginnings of agriculture and the rise of the first civilizations occur.

Humans are the only known species to have successfully populated, adapted to, and significantly altered a wide variety of land regions across the world.
