Naturalistic explanations are those, which assume that there were no forces involved in the history of life other than matter, energy, and the chemical and physical laws governing their interactions. Naturalistic explanations assume that there were no intelligent agents that could have influenced life in the past.
There are several problems with naturalistic explanation of life and lack scientific evidence that is said to supposedly support evolution. If you truly look at Darwin’s theory of evolution you will see that there is no way that it can explain how life truly began. According to Darwinism, “inherent in natural selection is the notion that those life forms best equipped to survive will win the struggle for existence.” The first problem is with “biology”. As millions of years passed and small changes occurred that slowly but surely left the organism more and more advanced and more fit to survive. They believe that living organisms are very complex, that one could not construct their existence. The second problem is with “Geology” with that once life does form, the fossil record indicates that biological complexity will change. The fossil record lacks the transitional forms; the evidence is proven against the naturalistic evolutionary transitions in the history of life. The third problem is with “Math Probability” with belief that life comes from non-life. The lack of support and the perception that it is not necessary to prove something that so obvious. One would argue with the lack of details.
You asked us to explain three problems, which I did and just wanted to mention that there are more problems with naturalistic explanation of life such as chemistry and physics. I would also like to note that I believe that there is a God and he alone created the entire universe.
