We don’t realize the unfathomable amount of chemical reactions and events that happen even in a tiny bit of living material. Every chemical reaction in life happens for a natural reason. There is locally no purpose in them, they are natural events. However, we dont see plain reactions, we see for example mitochondria, cells, etc. Life from a strictly biochemical perspective is a sum of chemical systems that interact. From a biochemical standpoint, there is not such a thing as an individual organism. This is probably a result of a need of human brain to organize and understand systems. Thus, we think that living systems can create order.
While in fact life as a whole, if we even include for example death, food and nutrient recycling is a much more disordered system overall, exactly like all spontaneously forming chemical systems. And similar systems under the same laws of nature will constantly produce similar results. Imagine you go to a planet with many chemical reactions on its surface. Your chemical analysis will be similar both now and after 30 years. Every chemical reaction in life happens for a natural reason, for example adenine and thymine form bonds during replication. There is no purpose in them, they are natural events. DNA molecules are a part of the soup, but they are stable and their interactions will be relatively preserved and will expand.
