Precambrian Time extends from 4.6 billion years ago to 540million years ago. that's the greatest expanse of geologic time.
The geologic time scale that represents the longest time span is the eon. It is a unit of time that is equal to a billion years.
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 is divided up by four major intervals. In order from Largest to smallest: Eons are the largest time frame covering hundreds of millions of years. Eons are divided into smaller time intervals known as Eras. Eras are subdivided into Periods. Periods are broken into finer subdivisions known as Epochs.
The geologic time scale shows the timing and relationship of events that have occurred throughout Earth's history.
Eon The largest expanse of time on the geologic time scale is the eon. An eon would encompass at least two eras.

Human existence has been very brief compared to the entire expanse of geologic time.
The geologic time scale.
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.
