"The second law of thermodynamics is an expression of the universal law of increasing entropy, stating that the entropy of an isolated system which is not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium." - A loose definition from the "scholarly" Wikipedia.
Some creationists state evolution cannot exist due to the 2nd Law of Thermodynamics. This is my favorite argument. They argue things should devolve over time in our closed system...so god must be the giver and designer of life. The key to the 2nd Law is the "isolated system" tidbit. Remember the huge, glowing orb that heats and lights the Earth? Yeah...it's called the Sun.
Also, I have a quibble with people who believe the Universe is not in chaos. Sure, some portions have some order. In a place as vast as the Universe, given enough time & due to natural laws...some order is bound to occur. They seem to forget the fact just about everything seems to be expanding at an increasing rate, stars are exploding, galaxies are colliding with on another and black holes are swallowing star systems like I down a bag of M&M's.
Let's narrow the focus, however, and just think about Earth. Our planet is periodically bombarded (on a geological time scale) by large objects from space. Tons and tons of new debris falls to the Earth every year. Our planet is blasted by X-rays & Gamma rays...even Stevie Ray, Ray Charles and Charlotte Rhea. And this is just a small example of what goes on on this "pale blue dot."
Yep...this is one orderly closed system he "created."
