The Stages of Evolution 💥💦💧💢💢💥

As mentioned in the previous post, we have four stages of evolution.

The first stage was Hadean; this was a period where nebular hypothesis has happened. The earth was formed by the debris; (the debris was part of a solar system). This is called as the nebular hypothesis. Hadean was a stage where there was no life. The formation of the moon has happened at this stage. The moon was formed 3000 billion years ago.
The earth is divided into three layers: crust, mantle, and core. The crust and core components are formed in the Hadean stage.
The second stage was Archean, this stage is divided into four stages,
a.Eoarchean
b.Paleoarchean
c. Mesoarchean
d.Neoarchean
The volcano's which were cooled down turned into the ocean and there was no oxygen in the atmosphere. The process of inhaling the oxygen was almost impossible until there were prokaryotes in the atmosphere which are unicellular organisms. The process of photosynthesis was started in Archean stage by Archean cyanobacteria which indeed given oxygen(o2) and taken carbon dioxide(Co2) from the atmosphere. The ozone layer(o2+o=o3) which is formed from the oxygen and protects the earth from the most powerful ultra-violate rays was not formed.  All these transformations have happened in the four stages of the Archean stage.
What would have happened after the photosynthesis? Where did a human being come from? How did a life start? Don't you get such questions into your mind?
Well, after the Hadean and Archean, there are two more stages Proterozoic and Phanerozoic which would reveal the existence of living beings.
The two stages will be explained in the next article.
Until then have a great time 😀😀😀😀
