Precambrian time covers the vast bulk of the Earth's history, starting with the planet's creation about 4.5 billion years ago and ending with the emergence of complex, multicelled life-forms almost four billion years later.
According to http://science.nationalgeographic.com/science/prehistoric-world/precambrian/, the "first multicelled animals appeared in the fossil record around 600 million years ago. There were three categories: sponges, cnidarians (such as jellyfish, sea anemones, and corals), an annelids (or worms).
In the earlier time of that era there was the proterzoic era, than archeon era, and then Hadeon Era. In the Hadeon Era thats when the earth formed. In the Archeon Era it was about 1 billion years after the Hadeon Era and thats when everything started to cool down. In the Proterozoic Era it was about 2 billion years ago there are two supercontinents, one visible across the equator on this side of the earth and another one on the other side.
The Precambrian is the earliest of the geologic ages, which are marked by different layers of sedimentary rock. Laid down over millions of years, these rock layers contain a permanent record of the Earth's past

This video is most likely how the earth was created when life even first existed the bacteria almost killed everyone and they couldn't get the right air so they have to defeat the bacteria to live and the EARTH WAS RUSTING FREAK OUT!!!!!!!!!!!!! But then they left but there is still some bacteria in the earth we shall KEEP FIGHTING!!!!!!!!!!!!!
Some of the things that happened in the Precambrian Era: Earth and it's moon formed. Oxygen became present. Many ice-ages. First life on Earth. First oceans. Many mass extinctions.

The first sign of life occurred in this era.
One significant event from the Precambrian era is when the Earth was getting created.
oceans and atmosphere form.
during this time it was one of the first times that life was on earth
Life was first made during this time.
Formation of a planet.
Pangea started to split apart.
A signifacant event that happend in Preambrian times were/are...The formation of the Earth, also first life animals and bacteria and worms.
Planet formation.
In the first Time or precambrian time the first life or bacteria. They also formed our planet.
Meteors hit Earth and they created the Continents we live on today.Worms,Fungi,and Bacteria were the first life on Earth.
The Hadean eon was when the Earth was forming and gravity pulled gas and dust from our solar system to create Earth.

The formation of the planet and the metors that brought water to earth over millions of years.
It took along time to have more living things on the earth.
The first fish evolved in this era.
the formation that made water
The first ice age, which might of been the harshest in earth's history.
formation of a PLANET
If the metior didnt hit we still would be in pangea
Formation of planet occured.
The Precambrian is the earliest of the geologic ages, which are marked by different layers of sedimentary rock. Laid down over millions of years, these rock layers contain a permanent record of the Earth's past
the first ice age was in this era.
Part of how the Earth was formed occurred.
the meteor of life gave life to earth and made us humans.

Chemicals in the water created life.
The first sign of life occurred in the Precambrian era.
chemicals in the water created life
A significant event from the Precambrian era is when the Earth was created.
A important event that happened during the Precambrian is snowball earth. This is when life really started to evolve.
The Earth was created during this era, and the first signs of life were starting to exist!
One significant event from the Precambrian era of the geological history of Earth is, formation of the Earth and Moon.
the earth formed
This video is most likely how the earth was created when life even first existed the bacteria almost killed everyone and they couldn't get the right air so they have to defeat the bacteria to live and the EARTH WAS RUSTING FREAK OUT!!!!!!!!!!!!!

meteor strikes creating water
the planet formed and catfish wer made lol
the fist human like creature named lusi
The Earth formed during the precambrian era. Thats kinda important I guess.
The first sign of life occurred in this era.
AIR
The Earth was created during this era and there were signs of life.
Hi Ruby!
The first sign of life occured in the precambrian era.
The first signs of life began to form.
oxygen was formed
Earth was made by meteoroids..... (which isn't true)
