it began at the start of the hadean eon after the chaotian and prechaotian eons
The first supercontinent that formed at the end of the Proterozoic eon is called Rodinia. It was formed around 1.3 billion years ago and eventually broke apart around 750 million years ago.
The longest era in geologic time is the Precambrian era, which lasted from about 4.6 billion years ago to 541 million years ago. It encompasses about 90% of Earth's history and is divided into several eons, including the Hadean, Archean, and Proterozoic.
Autotrophic prokaryotes enriched the atmosphere with oxygen during the Archean and Proterozoic eras, starting about 2.5 billion years ago and continuing into the early stages of the Proterozoic era. This process, known as the Great Oxidation Event, was a significant turning point in Earth's history, leading to the rise of oxygenic photosynthesis and the oxygenation of the atmosphere.
The permian period was the end of the paleozoic era.
It's not a brilliant question you haven't said what scale you're looking at - Cosmic, Geologic, etc,Geological time is divided as follows:Hadean 800 million yearsArchean 1300 million yearsProterozoic 1958 million yearsPhanerozoic 542 million years Paleozoic 291 million yearsMesozoic 184.5 million yearsCenozoic 66.5 million years Cretaceous PaleoceneEoceneOligocenePaleogeneNeogene MiocenePlioceneQuaternary PleistoceneHoloceneThe Earth is over 4.5 billion years old, We live in the Holocene Epoch of the Quatenary Period of the Cenozoic Era of the Phanerozoic Eon
i do not know thats why im asking you

Proterozoic
The answer is Proterozoic.
The Proterozoic era ended with the Cambrian Explosion, which took place around 541 million years ago. This event marked a rapid diversification of multicellular life forms, leading to the development of many complex organisms that laid the foundation for modern marine ecosystems.
The Precambrian era is divided into three subdivisions: the Hadean, Archean, and Proterozoic eons. These subdivisions represent different stages in Earth's early history, from the formation of the planet to the evolution of complex life forms.
The start of a new system of transportation, railroads, in the 1840's and 1850's caused the era of canals to end.
This three eras was included in the Proterozoic Eon.The first Era was the Paleoproterozoic Era;next is the Mesoproterozoic Era;then the last is the Neoproterozoic Era. This another three eras was according to the Phanerozoic Eon.The first Era was the Paleozoic Era;followed up by the Mesozoic Era;then the lastly was the Cenozoic Era.
The Proterozoic eon was the third eon in Earth history. It lasted from 2.5 billion years ago to 542 million years ago. Therefor, the Proterozoic was nearly 2 billion years long.
The first supercontinent that formed at the end of the Proterozoic eon is called Rodinia. It was formed around 1.3 billion years ago and eventually broke apart around 750 million years ago.
