They argue that there are many flaws in Darwin's theory and it is not scientifically sound. They are called Creationists. Evolutionists claim that the theory of evolution has many advantages to a society. Evolution provides an scientific origin for the the universe. A world without a Creator is desirable for those who want to believe there is no God.
Macroevolution appears to be a false theory.
The biochemical evidence indicates the cell is irreducibly complex, which means evolution was impossible and the cell could only have been formed by an intelligent designer. Molecular evolution has never addressed the question of how complex structures came to be. In effect, the theory of Darwinian molecular evolution has not published, and so it should perish. No one at Harvard University, no one at the National Academy of Science, no Nobel Prize winner - no one at all can give a detail account of how the cilium, or vision, or blood clotting, or any complex biochemical process might have developed in a Darwinian fashion. But we are here.
