The Evolutionists' Dilema

I've a couple of questions for all those who claim evolution is the only rational explanation for man's presence on this planet.

First, how does evolution even work within the context of the laws of thermodynamics, particularly entropy? Think about it: in very simple terms, entropy states that the universe is gradually decaying from a universe of great order to a universe of totaly random chaos with everything being the same temperature. Evolution flies in the face of this by saying that of all the processes we know, the most complex process of all, life, started by itself and increased its order and complexity through purely random events. The realitiy is, both processes are mutually exclusive: either random things change from more order to less order (entropy) or they change from less order to more order (evolution) or random changes have no net effect over time because all of the random permutations cancel each other out.

Secondly, if we really are the result of random changes alone and that survival of the fitest is the sole key in determining which species lives on and which one dies out. Why don't we now live forever or much longer than we do with the bodies we have? It would seem that those who live longest would reproduce the most and thereby edge out those who don't reproduce as long. But that hasn't happened. Why?

Bottom line: entropy is an observed and well proven law. The universe is decaying to a state of totaly random and homogenous chaos. It is losing its order. But, it is perfectly reasonable to see how a creative force outside of the universe (God) created life that could exist and even thrive within this context of decay. No other paradigm about how life came to be makes sense.
