When did man first appear on Earth?
Bones of primitive Homo sapiens first appear 300,000 years ago in Africa, with brains as large or larger than ours. They’re followed by anatomically modern Homo sapiens at least 200,000 years ago, and brain shape became essentially modern by at least 100,000 years ago.
Where was the first human life on earth?
The first humans emerged in Africa around two million years ago, long before the modern humans known as Homo sapiens appeared on the same continent. There’s a lot anthropologists still don’t know about how different groups of humans interacted and mated with each other over this long stretch of prehistory.
How long have humans existed on Earth?
While our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago. Civilization as we know it is only about 6,000 years old, and industrialization started in the earnest only in the 1800s.
How did life form on Earth?
It seems possible that the origin of life on the Earth’s surface could have been first prevented by an enormous flux of impacting comets and asteroids, then a much less intense rain of comets may have deposited the very materials that allowed life to form some 3.5 – 3.8 billion years ago.
How old is the first person on earth?
The first answer is to assume the first “person” was the first member of our species, Homo sapiens. This person would have been just like you and me, but without an iPhone! The oldest skeleton discovered of our species Homo sapiens (so far) is from Morocco and is about 300,000 years old.
Why is Earth the only planet with human beings?

Why does human life exist on Earth?
Life is able to exist on Earth because of a small number of reasons. It has the right climate, water is abundant, its air is breathable, it receives the perfect amount of energy from the Sun and is able to protect itself from the Sun’s harmful rays and particles because of its atmosphere and magnetic field.

Homo sapiens, who are the modern form of humans evolved 300,000 years ago from Homo erectus. Human civilizations started forming around 6,000 years ago.
