Over the last few weeks we have been discussing human immunity. In the first part of the article, we discussed the basic functions of the immune system and the two different kinds of immunity. In the second article, we discussed in greater detail how the various parts of the immune system work. In this third concluding part, we will discuss how we got our immune system.
Evolutionists claim that immunity is simply a natural progression for all creatures in the continual struggle to survive. The fact that there are numerous similarities between various creatures immune systems, such as phagocytosis, has lead evolutionists to claim that slow gradual upward progression has led to the human immune system. Since just about every creature shows a basic ability to identify self, and thus recognize a foreign cell, evolutionists believe they can form a pathway of evolutionary development.
However, like everything else in evolutionary theory, there are significant problems with its attempts to explain how immunity evolved. The largest problem is a complete lack of ability to explain where the first immunity came from. In order for evolution to be a viable theory, it must have the ability to explain the origin of everything, including immunity. The first immunity would have arisen in bacteria by evolutionary logic. Yet why a bacteria would develop immunity or what pathway such a development would follow has yet to be explained or established. Immunities origins are as mysterious as the origins of life itself to the evolutionist.
A second significant issue are the immunoglobulins. based on evolutionists own timeline, immunoglobulins, better known as antibodies, developed around 200 million years ago, which is approximately the same time that amphibians appeared in the fossil record. Note that amphibians are believed to have developed from fish. Thus amphibians should have been the first vertebrates to develop antibodies, fish should have none. Yet fish with jaws do have antibodies. Something is wrong with the evolutionist timeline. Amphibians did not evolve back into fish, so how did fish develop antibodies? Did they develop in parallel? If evolutionists use this explanation, the already long mathematical odds against their theory double, as the same thing now has to develop twice.
A third challenge to evolutionary theory is the incredible complexity of the immune system. The immune system is far more complex than I have been able to detail in this article. This incredible complexity with thousands of moving parts all working together to defend the body against pathogens demands a thorough explanation for its origin. Evolution has no such explanation. Merely explaining the T cells is incredibly difficult, and they are but one part of the thousandfold immune system. Evolution must explain every single part naturally in order to be viable.
The fourth challenge is the ability of every creature to self-recognize. The method of this self-recognition is well known. It is performed via antigens on the bodies own cells. The question is how these antigens developed in the first place. Why would a mindless chance process recognize the need for the body to tell the difference between itself and an outside cell? To recognize that need, and account for it via the antigens, requires intelligence, something evolution was never accused of having an abundance of. Antigens exist, but why evolution would create them is a mystery.
A fifth and final challenge to evolutionary theory ties back into the existence of antigens, that being the existence of Memory B cells. These cells that remember specific antigens of foreign cells are a vital part of adaptive immunity. The question for evolutionists is how did they develop their remarkable ability? A blind mindless process would not see the incredible value of having memory cells to defend against a pathogen. This requires intelligence. Intelligence such as might be found in an omniscient Creator God.
Creationists have no problem with immunity. When God made man, He knew man would fall, and thus become susceptible to disease. As such, in making man, God equipped him to deal with the pathogens he would face when he fell. This takes faith to believe, but accounts for all the challenges I pointed out to evolutionists ideas. Evolution has no answers for these questions. Until they can be answered, evolution remains an unproven hypothesis.
