The Geologic Time Scale is the history of the Earth broken down into four spans of time marked by various events, such as the emergence of certain species, their evolution, and their extinction, that help distinguish one era from another.

How was the planet Earth born?

Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.

How did the world start?

A big bang to be exact! Billions of years ago, all matter of the universe was compressed into one tiny point until it finally exploded around 12-14 billion years ago. This explosion is what scientists call the Big Bang. During this time, humongous masses of dust and gas spewed throughout space.



How did humans start on Earth?

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. Then some of them spread from Africa into Asia and Europe after two million years ago.

How did all life begin?

Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.

What era are we currently in?

Officially, the current epoch is called the Holocene, which began 11,700 years ago after the last major ice age.

“The Sun” is also considered proper nomenclature. Thus, it is likely that “Earth” (also considered proper,) as the third satellite of Sol is either properly Sol III, or Sol-3. Our Moon (again, considered proper) would be Sol IIIa, or Sol-3a. Also correct would be Sun III, Sun-3, Sun IIIa, and Sun-3a.
