Pre-PrΓ¦terian is a first and earliest geological supereon of [ππππππ-πππ-π ππππ-πππ] before Vitazoic eon, it has three divided eons. This supereon started around 4817 Β± 0.16 million years ago, until 788.8 Β± 0.16 million years ago. Which 88% of the geological time of [ππππππ-πππ-π ππππ-πππ] is on this supereon.
In today, the 88.2% of the geological time of [ππππππ-πππ-π ππππ-πππ] is part of this supereon.
The [ππππππ-πππ-π ππππ-πππ] was borned. Where there's no water and life, but a hell with worldwide volcanic activity and chaotically very hot temperature. Until the "major impact". Which caused new major changes of the whole planet.
