It is well known that, left to themselves, chemical compounds ultimately break apart into simpler materials; they do not ultimately become more complex. Outside forces can increase order for a time (through the expenditure of relatively large amounts of energy, and through the input of design). However, such reversal cannot last forever. Once the force is released, processes return to their natural direction - greater disorder. Their energy is transformed into lower levels of availability for further work. The natural tendency of complex, ordered arrangements and systems is to become simpler and more disorderly with time.
In the long run, complex, ordered arrangements actually tend to become simpler and more disorderly with time. There is an irreversible downward trend ultimately at work throughout the universe. Evolution, with its ever increasing order and complexity, appears impossible in the natural world.
"Of all the statements that have been made with respect to theories on the origin of life, the statement that the Second Law of Thermodynamics poses no problem for an evolutionary origin of life is the most absurd… The operation of natural processes on which the Second Law of Thermodynamics is based is alone sufficient, therefore, to preclude the spontaneous evolutionary origin of the immense biological order required for the origin of life." (Duane Gish, Ph.D. in biochemistry from University of California at Berkeley)
World-renowned Evolutionist and avid anti-Creationist Isaac Asimov confirmed that:
"Another way of stating the second law then is, 'The universe is constantly getting more disorderly!' Viewed that way we can see the second law all about us. We have to work hard to straighten a room, but left to itself it becomes a mess again very quickly and very easily. Even if we never enter it, it becomes dusty and musty. How difficult to maintain houses, and machinery, and our own bodies in perfect working order: how easy to let them deteriorate. In fact, all we have to do is nothing, and everything deteriorates, collapses, breaks down, wears out, all by itself - and that is what the second law is all about."
Isaac Asimov, "In the Game of Energy and Thermodynamics You Can't Even Break Even", Smithsonian Institution Journal (June 1970), p. 6
"The Second Law of Thermodynamics states that the amount of available work you can get out of the energy of the universe is constantly decreasing. If you have a great deal of energy in one place, a large intensity of it, so that you have a high temperature here and a low temperature there, then you can get work out of that situation. The smaller the difference in temperature, the less work you can get out of it. Now, according to the Second Law of Thermodynamics, there is always a tendency for the hot areas to cool off and the cool areas to warm up—so that less and less work can be obtained out of it. Until finally, when everything is one temperature, you cannot get any work out of it, even though all the energy is still there. And this is true for EVERYTHING in general, the universe all over."
