The entire history of humankind is but a blink of an eye next to the vastness of geological time.
Geological time scaleThe geological time scale (GTS) is a system of chronological measurement that relates stratigraphy to time, such as location the period of time when a significant event that has happened, the time can even be dated back to the history of when the earth first existed. This strategy is commonly used by geologists, paleontolosists and many other Earth scientists to describe the timing and relationships between events that have occurred throughout Earth's history. Getting into more depth, the arrangement with GTS are determines by unites of time from what was found inside the layers of the rocks. Such as the changes made in the layers of the rock and the specific characteristics of the time. The above conditions can help the worker to track more precisely of the event that had happened.

Geologists and paleontologists measure the Age of the Earth and the History of Life in millions and billions of years. For this reason a special kind of "calendar" is required; one that measures not weeks, months or years, but millions, tens of millions and hundreds of millions of years. This is the Geological Time-ScaleThe Geologic Time-Scale is divided into units. From the largest to smallest these are: Eons, Eras, Periods and Epochs. Each of these time periods had different conditions and unique ecosystems. Their beginning and end are often marked by some event such as a mass extinction, the appearance of new life, a change in the rocks' magnetic signature, or by human convention.
