Ahh yes, the old entropy canard...

I'm interested in observations that illustrate increased order and complexity.
Paul, what you've got here is an example quite common, when theists have a go at using the second law of thermodynamics to support their position.
You also seem to have done what is most commonly done when using this argument, that is, misinterpret the results, possibly misunderstanding the second law itself.
The key concept is that entropy, in an isolated or closed system, over time, is always greater than zero. Always. What is often missed is the concept of the closed system.
This is usually the result of an anthropocentric or geocentric cosmology, which all too often fails to allow that the earth is not a closed or isolated system. Indeed, we see many examples of complexity on earth that should not otherwise exist. We are the most obvious example.
Very little of what we know now exists, including ourselves, would exist were it not for an external source of energy, the sun. That is what drives all life processes on earth.
Taken as a more closed system (which it isn't, in fact), the solar system is indeed running down. The sun is roughly halfway through its life. Angular momentum is being slowly more evenly distributed. In four or five billion years, this little solar system will not be recognizable.
But, back to our local situation. The amount of hydrogen that has fused into helium in the sun since the dawn of life on earth, far surpasses the energy even received by the earth from the sun during the same time. The amount of entropy in the earth-sun system alone has increased dramatically.
Does this shed a little light on how the second law of thermodynamics holds true, while we still see a local decrease in entropy (for now, at least)?
