Precambrian
This period is also split into two Eons: Archean (from 2.5 billion to 4.5 billion years ago) and Proterozoic (from 542 million to 2.5 billion years ago).
The geologic timescale is represented as a calendar year for easier understanding of the vast span of time. In this representation, the Earth's formation occurs on January 1st and the present day occurs at midnight on December 31st. This compressed timescale helps to comprehend the timeline of Earth's history within a familiar context.
The span of geologic time subdivided into periods is called an era. Eras are further subdivided into periods to help scientists classify and study the Earth's history in a systematic way. Each period represents a distinct interval of time with its own set of characteristic geological and biological events.
The Earth's geologic time scale spans about 4.6 billion years, from the formation of the Earth to the present day.
Eon is the broadest division on the geologic time scale, representing the longest time span. Eons are further divided into eras, which are then subdivided into periods, epochs, and ages.
The unit of measurement called the span is equal to 9 inches. There are 2 spans in one cubit.
The Precambrian Eon represents about 88 percent of geologic time on Earth. This eon includes all time prior to the Paleozoic Era and spans from the formation of the Earth about 4.6 billion years ago to the beginning of the Paleozoic Era around 541 million years ago.
A long span of geologic time is called an era. This is a major division of geologic time that is further subdivided into periods. Examples of eras include the Paleozoic, Mesozoic, and Cenozoic.
an era is a very long span of geologic time

because the time span of earth past is so great geologic

4.6 billion years
4.6 billion years
Humans span roughly 0.0044% (about 4 thousandths of one precent) of the time since the Earth was formed.
Erosion of already deposited layers or a time span of non-deposition.
The longest in geological time is an Eon eg. Archeozoic Eon . Edit: there is also the supereon, which is usually composed of 2-3 eons.
Probably it is dung that is a fossil
