Appearance of the First Living Unit on Our Earth

The physical life of our Earth was sterile and lasted for 3.75/3.8 billion years when the first living
substantial unit that is the biological life appeared. Here we want to tell you only that this unit was a
bordered temporary substantial structure/matrix which needed and could accept the external –
electromagnetic or/and chemical – energy and which was suitable to maintain a life-long continuous
electron and ion transport that is its own metabolism as well as to produce different compounds and
emit metabolites as well as heat further which had the ability of reproduction. The start of the life of
that unit is unknown but it could begin only in fluid water with optimal substantial, energetic and
environmental conditions including the entropy of our Earth, too. The first living unit was born about
800–750 million years ago. That fact means that not only C, O2, water and different inorganic as
well as organic compounds which were needed for its life but also the convenient form of energy
which could be accepted by it had already appeared during the atomic and the abiotic chemical
evolution.
