Origin of life How did the living come from the non-living?
According to the Big Bang theory, the 'origin of the universe' happened as a result of the Big Bang, 15 billion years ago from today.
About 10.5 billion years after the Big-Bang, that is, 4.6 billion years ago, the solar system evolved, in which planets and satellites were formed.
Thus, the origin of the Earth was about 4.6 billion years ago from a burning gaseous body. In about 0.6 billion years, the Earth's Crust was formed on the above gaseous body.
The period of formation of the crust was given the name of Azoic Cray.
The history of the Earth from the inception of the Earth's surface to the present day has been designated as the Zoic era.
The 'origin of life' was the first to take place in the Adisagar, 3.8 billion years ago, in the Archaeozoic era of the Jivi Mahakalpa.
