The presence or absence of fossils has been used to compare the relative ages of rocks around the world and to arrange sedimentary rocks into a geologic time scale. Eons are the largest intervals of the time scale and range from 540 to 2,050 million years in length

The geologic time scale covers the entire history of Earth, which spans approximately 4.6 billion years. It is divided into eons, eras, periods, epochs, and ages to categorize and study Earth's history.
The geologic time scale.
The Geologic Time Scale is measured in years, often in millions or billions of years. The age of our solar system is about 4.5 billion years. The 'geo' part of the name means it refers to our Earth.
Geologic Time. It's called the Geologic Time Scale.
Precambrian is the largest division of the geologic time scale.
Phanerozoic is the eon which geologic time scale means visable life.
The Precambrian
in the scope of geologic time, how significant is the presence of humans?
Cenozoic
On a geologic time scale, yes. On any other time scale, no.
