Fallacy: Abiogenesis is not part of the theory of evolution
The exclusion of abiogenesis from the general theory of evolution is illogical on two counts. First, a central tenet of evolutionary theory is that no intelligent design exists. Having made that contention, those who profess Darwinism remain responsible to refute every line of evidence to the contrary, including the explanation as to how life could have gotten started without intelligent design. If intelligent design was required to create life, then the central assumption of Darwinism has been refuted.
The second logical fallacy is the arbitrary delineation as to when evolution begins. Central to the theory of evolution is the assumption that all life can be reduced to chemicals. The doctrine of gradualism contends that no sharp distinction between life and non-life exists. If a bacterium was the "first life", then it was preceded by a non-living entity. No biologist believes that. If a bacterium was preceded by a simpler life form, then there is no logical reason to exclude that study from the theory of evolution. All theories of abiogenesis include autonomous self-reproducing entities that supposedly led up to more complex single cell life over about one billion years of earth's history. Since no one can propose a viable life form simpler than a bacterium, it has been declared that a bacterium is where “evolution” begins. Thus, the exclusion of abiogenesis from the theory of evolution is the exclusion of one billion years of history of evolving life forms. With this perspective in mind, it is obvious that the exclusion of abiogenesis from the theory of evolution is arbitrary and self-serving.
If one insists that evolution is the study of the ancestry of living forms, then one should begin that study with the first self-replicating entities. Because evolutionists cannot account for one billion years of supposed evolutionary history, they have arbitrarily drawn the line at a modern bacterium, supposing that anything simpler than that is not part of the theory of evolution.
Abiogenesis is fundamental to evolution because proposed mechanisms of evolution occur on a molecular level. It is believed by many evolutionists that DNA is not as complex as it is, and that chemistry itself possesses properties of life. It is believed that chemistry can not only create life, but can somehow direct the rearrangement of nucleotides to result in complexities of DNA code. This belief is adopted only because of a pre-held belief in evolution. The general theory of evolution, as viewed by most Darwinists, encompasses everything from the Big Bang to the present day, and abiogenesis is fixed in the center of it.
Frequently the concession is made by evolutionists that God might have created the first single cell life just to get the evolutionary process started, but thereafter retreated and allowed natural selection to take its course. Later in life, Charles Darwin admitted that perhaps the first life was formed by an intelligent creator.* This separation of evolution from abiogenesis leads to the suggestion that God might have been necessary to create life, but thereafter was not necessary. Since so many conceptual impossibilities to evolution are obvious, it is illogical to suppose that God was necessary to solve one enormous obstacle, but thereafter was not.
