The Second Law of Thermodynamics states that the amount of entropy in the universe always increases and will some day reach a maximum when no useful energy is left and disorder is total. Equivalently, perpetual-motion machines of the second kind are impossible. This does not designate that life cannot come from nonlife.

In 1951, Stanley Miller and Harold Urey, two scientists at the University of Chicago, combined the gases that are the ingredients of the Earth's atmosphere in a flask and zapped the flask with an electric charge, the kind Nature provides in the form of lightning.

They wound up with organic molecules, including an astounding variety of amino acids, the basic building blocks of proteins, which are the prime components of all life on Earth. They demonstrated that life could arise from inanimate matter.

Scientific theories are never absolutely proven. They are accepted as known facts when they are confirmed by observation or experiment. Evolution by natural selection is such a scientific theory.

Carbon dating is extremely precise. It is based on carbon-14, an isotope of carbon, with a half-life that can estimate the age of carbon-bearing materials up to about 58,000 to 60,000 years. All life-forms on Earth contain carbon-14.

To develop a mature toleration and modern understanding of evolution, I recommend the book "The Greatest Story Ever Told" by Richard Dawkins.
