The Precambrian is the largest span of time in Earth's history before the current Phanerozoic Eon, and is a Supereon divided into several eons of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago (Ga) to the beginning of the Cambrian Period, about 541.0 ± 1.0 million years ago (Ma), when hard-shelled creatures first appeared in abundance.
There is no indication as to how long the first trump will last, but assuredly it will last long enough for all peoples of the world to hear it.
If it is managed carefully it will last a long time, especially if you do not disturb the capital but only take the earnings.

• PRECAMBRIAN EON (noun)The noun PRECAMBRIAN EON has 1 sense:1. the eon following the Hadean time and preceding the Phanerozoic eon; from about 3,800 million years ago until 544 million years agoFamiliarity information: PRECAMBRIAN EON used as a noun is very rare.your lovely Chloe xxx
3.5 billion years ago was the Paleoarchean Era(3,600 - 3,200Ma). This was in the Archean Eon(3,800 - 2,500Ma) & during the Precambrian SuperEon(4,500 - 542Ma).
The earth first formed at the beginning of the Precambrian supereon which spans a very large period of time from 4,567 million years ago, through to 542 million years ago.The beginning of the Precambrian where Earth formed is known as the Hadean eon, stretching from 4.7 Ga (billion years ago) and ended roughly 3.8 billion years ago.
The Precambrian is a long period and just as Earth has many climates now, it had many then.
Supereon is the longest classification of time in geology. The Precambrian period is a supereon comprised of the Hadean, Archean, and Proterazoic eons.
Precambrian is an informal term for the time before the Cambrian Period, the first period of the Phanerozoic Eon. The Precambrian consists of three eons, the Hadean, the Archean, and the Proterozoic. The Hadean Eon is about 760,000,000 years long. The Archean Eon is about 1,300,000,000 years long. The Proterozoic Eon is about 1,960,000,000 years long This comes to a total of 4,025,000,000 years.
supereon, composed of multiple eons
The Precambrian Super-Eon lasted from 4,576.2 until 542 million years ago approximately 4.0422 billion years.
Precambrian is BEFORE the Cambrian period!
The Precambrian is the informal name for the large expanse of time preceding the current Phanerozoic Eon. It began with the Earth's formation about 4.5 billion years ago and lasted until the advent of multicellular life about 542 million years ago. Overall the planetary environment was drastically different. Life appeared sometime late in the Precambrian, but it is not known when. The Precambrian "supereon" is divided into three eons: the Hadean, Archaean, and Proterozoic. Very little is known about the Precambrian, despite the fact that it comprises nearly 90% of the Earth's history. This is simply because Precambrian rocks are so old, and are either heavily metamorphosed, have been destroyed by erosion, or remain buried deep beneath Phanerozoic strata.
There is some debate among experts, but it is generally accepted that the Precambrian lasted from 3.9 to 4 billion years. This time period is made up of three eras which are the Paleoproterozoic, the Mesoproterozoic, and the Neoproterozoic era.
It is 4 billion years
