Evolving Hitchikers in the Galaxy

I just saw the Hitchiker's Guide to the Galaxy. The movie was the long awaited adaptation of Douglas Adams's radio show, book, and BBC short series.
The book is the first of five in the "Hitchiker's trilogy". It tells the story of Arthur Dent, who joins the imperturbable alien Ford Prefect on an interstellar journey, after the earth is destroyed by the Vogons (another alien race) to make way for an interstellar bypass. The book (and movie), however, is more of an excuse for Douglas Adams, through the voice of the electronic "Guide", to explain his philosophy about Life, the Universe, and Everything.
His main point: Humans aren't so special. They are an insigificant race in "the unfashionable end of the Western Spiral arm of the Galaxy". "[Earth] is an utterly insignificant little blue-green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea..." (remember this was written in the 80's).

In fact (possible plot spoiler here) they are the outcome of a computer program. The Earth is not actually a proper planet at all (please see the film or read the book for clarification).

Douglas Adams was a devout atheist, and quotes the evolutionist bible "The Blind Watchmaker" by Richard Dawkins (brilliant book by the way) as his favorite book. The ideas in "Hitchiker" and many of his other books bring out this idea behind the absurdity and silliness of the plot. They are brilliant. Funny, silly, absurd, and incredibly intelligent.
Evolution has managed to get itself back in the presses. It's a scientific theory that has proven to be correct in explaining countless scientific phenomenon. The people who criticize it use disagreements over its mechanisms as an excuse to call the theory itself into question. However, it's pretty close to what a non-scientist would call a "fact". Its premise can be quite threatening to those that believe that humans are the center of the Universe. It can also be threatening to those who believe in God.
Do I believe in God? Honestly, I don't know. I believe there is a lot that we (as humans) don't know or understand. I swing back and forth as to whether that lack of understanding, can be called God, or is just the chaotic and amazing mix that's explained by the things we call physics, chemistry, and biology. Perhaps the answer is a mix of both. I certaintly don't know.
I do agree with Adams, in that we need to think that we, as humans, are not more important than the rest of nature. We are a apart of nature, and we happen to have the power to affect the planet, both for good and bad. We have to use that power carefully, or it will destroy us.
