From the origin of the earth until the first eukaryotic cells appeared (4.6 billion year ago until 2.5 billion years ago) was called the Archaean Eon.
First organisms formed, pangaea came together, homo sapiens lived. There are lots of good images on google.
Scientists use the geologic time scale to outline the history of life on Earth. This scale divides Earth's history into different time intervals based on major geological and biological events. It includes periods, epochs, and ages that help scientists understand the timing and sequencing of events in the history of life on our planet.
In geologic time, the Hadean is the first EONof Earth's history, from it's formation 4.57 billion years ago to about 4 billion years ago. The Hadean is not an era, which is a smaller subdivision of geologic time.
Most geologic periods are named for the location where rock formations were first found that contained fossils from that period, some others (e.g. Carboniferous) were named for materials associated with the fossils.
The formation of the Earth is the earliest geologic event.
He was Neil A. Armstrong.
Homer is not called the Father of History. Herodotus is called the Father of History (at least in the western world) because his history is the first to look for logical casues for the events he depicts.

Historical geologists divide the history of the earth into for units of time called Eras. The first one that began when the earth formed---- 4.6 billion years ago---- was called the Precambrian Time. The next--- after the PT--- was known as the Paleozoic Era. The third--- when dinos roamed--- was called the Mesozoic Era. The on we live in is called the Cenozoic era.
The first muganda if you follow history was called muntu who produced twins and one of them was called Kintu who is mistakenarly called the first muganda, but the first muganda was muntu.
It's called lithosphere as I remember in science.
The methods the geologists used when they first developed the geologic time scale. Were studying rock layers and index fossils worldwide. By Patrick
