Abiogenesis or origin of life refers to the process by which life naturally develops from non-living matter to simple organic compounds ( Bergman, 2004). While the facts about a biogenesis are still unclear, the prevailing scientific theory suggests that the change involves a gradual process. From a simple organic compound, there is an observed increase in complexity, which affects replication leading to the development of cell membrane. Although there is uniform agreement among the scientists, on the occurrence of abiogenesis, the theory still lacks a clear model hence leading to disapproval. This piece, therefore, explains the existence of abiogenesis through three processes such as chemical, geophysical and biological means. Furthermore, it explores how the theory of the origin of life differs with the scientific viewpoint below. The study of abiogenesis combines all the three aspects of chemical, biological and geophysical means. The chemical theory on a biogenesis states that there are pre-life series of chemical reactions that give rise to present life. It further explains that living matter composes of carbon and water that is necessary for its function. The carbon and water undergo specialized chemistry to form four chemical families’ namely amino acids, lipids, and carbohydrates ( Gentili & Jumpponen, 2006) . The amino acid, which forms a significant constituent of protein in a living organism can be manufactured from the inorganic compound. The manufacturing process, however, requires special conditions such as lightning and radiation to catalyze the reaction. The theory also points out that the catalysis process in chemical reaction leads to the formation of precursor molecules, which are important in the self-replication process ( Fox, 1975) . The complex organic molecules can be found in the solar system, which may have acted as foundation materials for the development of present life. The next procedure that explains the origin of life involves biological concept. The concept links the source of life, with the branching of bacterial species. Biological view point of abiogenesis suggests that life developed instantly after the formation of oceans ( Bergman, 2004) . It acknowledges that there is similarity in the structure of the bacteria found near water vents, to that of microbes in the present era. The similarity in the structures provides support for the theory that the origin of life started near hydrothermal vents. Another evidence that supports the origin of life concerning the biological thought is the presence of elements such as oxygen, nitrogen and phosphorus in old Metasedimentary rocks. These elements can be traced in the inorganic compound and also inorganic compounds hence supporting the theory of abiogenesis. Finally, geophysical concept also supports a biogenesis. According to geophysical view point, the earth's atmosphere consists of hydrogen from ammonia, water vapor and methane, which are conditions that are conducive for the development of organic molecules. This development of complex organic molecules from inorganic compound supports the origin of life from non-living compounds. On the other hand, scientific experiments conducted by Fansesco Redi and Louis Pasteur disapprove abiogenesis theory. According to his experiment, using a maggot in covered and uncovered jars, Redi observed that no maggot appeared in the covered jar while in the open jar there were some maggots (Gentili & Jumpponen, 2006). He argues the flies were able to land in the open jar to reproduce hence acting as the origin of life. Again, Louis Pasteur, after doing a series of experiments, concluded that life only comes from life and this disapprove the abiogenesis theory. Pasteur uses a set of flasks to conduct his research, with boiled broth inside them. His design could allow free flow of air from outside to mix with air from inside the flask ( Geison, 2014) . Pasteur observed that some flask’s neck was broken and there was microbial development in the broth hence, origin of life.
