Darwinian evolution is not a science. Lets do the math.
The scientific method is used every day in forensic science to determine whether an event in a crime scene was an accident or by design and intention. Mathematical probability is a scientific argument and is frequently used in determining many issues of scientific inquiry.
The scientific method cannot be used to prove events which occurred outside of human observation. No one observed the origin of the universe by either chance or design, but scientific evidence via mathematical probability can be used to support either a chance or design origins for the universe.
If you went to an uninhabited planet and discovered only one thing, a cliff carved with images of persons similar to what we find on Mt. Rushmore, you cannot use the scientific method to prove that these images came about by design or by chance processes of erosion.
Mathematicians have said that any event with odds of 10 to the 50th power or over is impossible even within the entire time frame of the supposed billions of years popularly assigned for the age of the universe.
