Abstract

The author thinks that the endless and timeless Universe is a permanent substance and energy flow as well as movement of celestial bodies. Celestial bodies may have physical and biological life. The life of our Earth can be divided into different periods and ages. Its physical life was sterile. Essence of the biological life is the existences of a living unite which is a substantial matrix with a permeable wall which separates it from its environment. Through its wall during its life on and back directed movement of substance and energy exists. Effects of the living unites during their total existence determine the biological life of our planet. Our Earth is a closed system for the living unites. Substantial and energetic processes mainly those which have happened from 1778 on the Earth are analyzed in this paper.
