This article examines the main arguments concerning the nature of life's early beginnings. It first places biogenetic processes in a physical and systems-theoretical context. In this case, biogenesis would not involve the chemical construction of individual molecules, but rather the creation of an energetically self-sustaining, dynamically organized chemical system from the ground up. This system would have initially separated from the general operating physicochemical processes, gradually becoming more independent of them. As a system, it had to build its structure step by step, with each stage becoming more complex and stable than the previous one. Changing its basic structure too much; as long as a system's structure remains intact, it will continue to operate in the same way even if its chemical constituents change. This property of a system was especially useful when the systems, which had already evolved and operated for approximately 1.3 billion years, had to adapt to new environmental conditions during the Great Oxygen Event, or GOE, which occurred approximately 2.5 billion years ago. As energy processing systems, their constituent molecules carry the energy and can thus be replaced by other, more efficient ones as needed or as external chemical conditions change. It is the energy flow that began and has continued to exist. continued to change chemically, but for this to occur, the general physical conditions of the environment must have remained more or less constant. This automatically transforms the general problem from one of chemistry to one of thermodynamics and physical inorganic chemistry. It also implies that biogenesis does not concern the origin and evolution of individual chemical components, but rather the splitting off of processes of intense interactions that gradually diverge from those in the early oceans to form an increasingly distinct system governed by an energy flow.
