The ControversyConflicts between Evolution and Creationism occur when evolutionists argue that creationism is not a scientific theory because it cannot be tested by the scientific method, whereas creationists argue that evolutionists do not take God into account and that evolution is just a theory rather than a fact. Scientific methodology which is based on physical evidence can never be reconciled with the creationist faith-based belief that the Old Testament of the Bible, which was written by Israelites around 1400 BC, is the only true account of creation. Creationists continue to ridicule Charles Darwin even though his theories have been confirmed through many scientific studies.Science requires that a hypothesis or theory should be testable and supported by physical evidence, whereas religion requires acceptance of a doctrine or belief without analysis or judgment. For this reason, conflicts between evolution and creationism can never be resolved. DNA testing has shown that humans and chimpanzees have a 98-percent genetic similarity, providing overwhelming evidence that apes and humans have a common ancestry. Scientists are willing to accept these results as evidence that man is a specific type of ape, but this is what creationists find most revolting, since they believe that "God created man in his own image", as stated in Genesis 1:27.
