Let us first take a brief look at the history of life on the Earth. It is estimated that the Earth on which we live was born as a member of the solar system approximately 4.6 billion years ago. And it is thought that the first life on the Earth, that is self-replicating molecules resembling genes, were born several 100 million years later, about 4 billion years ago.
