We should search the origin of life on the earth in microbes and viruses

Origin of life on our earth is a mystery. Nobody exactly knows when the first life appeared on the earth. But it is sure that
the basic constituents of life like Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorous combined in a proportionate
way to create first life on earth. We know that for any chemical reaction an optimum temperature, pressure, catalyst & reagents
are required which if present in suitable proportion, the reaction can occur & the desired product is formed. Probably the
origin of life started in the first production of a purine, pyrimidine rings, amino acids & nucleic acid chains & the first life on
earth is prokaryotic microbes & viruses. So it is clear that we should search the origin of life in viruses & microbes which are
the smallest living particles. Microbes and viruses are the living specks of dust & probably it was formed even when the earth
was hot. Archaebacteria, thermophiles, methanogens are the proof that living organisms can even survive in high temperature,
acidic pH & absence of oxygen. These microbes originated long before the origin of higher plants, as for the production of
fertile land suitable for growth of plants, microbes are required. Inorganic substances, water &microbes for many years formed
the layer of fertile land on the surface of the earth. Structure of viruses which are lacking the cytoplasm & definite cellular
structure but containing nucleic acid core & protein covering are the proof that nucleic acid strands were first produced but
as they cannot survive independently, in presence of water they created the desired products to form cytoplasm & biological
membrane to create a primitive cell. To make it logically more comprehensible the origin of life can be divided into several
steps discussed below –
Step I – Formation of basic structural elements or building blocks of life like purine & pyrimidine rings, amino acids, glucose,
phosphate energy bonds etc.
Step II – Formation of more complex structural forms by chain elongation of basic structural molecules.
Step III – This is the most vital or crucial step where systematic assembling of all these structural elements lead to a structural
unit with functional autonomy where all the biochemical reactions can occur automatically, repeatedly in an organized way,
making it an autonomic functional unit capable of biochemical synthesis, degradation (metabolism), energy production &
self-duplication (reproduction).
