Time on my hands.
I wrote this back before the courts in Pennsylvania pimp-slapped intelligent design out of the science class room. I worked really hard to make the simple graphics as accurate as possible, and I didn't want it to sit forever ignored on my hard drive. Now it can sit forever ignored on my blog. Cheers - KDB
A very good friend who was my roommate while he was working on his PhD in theoretical physics once told me that one of the unwritten laws of physics is, “That which is not expressly forbidden is compulsory.” In other words, unless there is a darn good reason why something will not happen, probability demands that given enough time it will happen. That’s evolution in a nutshell. All you need is a lot of time. Luckily for us a lot of time has passed on this rock we call earth. As James Hutton, the father of modern geology, famously said of the earth, it shows “no vestige of a beginning, no prospect of an end.”
The earth formed 4.56 billion years ago (Ba). During its accretionary period the earth was being bombarded with a large number of meteorite and comet impacts. Those impacts have continued with decreasing frequency to this day. It has been discovered that many basic organic compounds exist in meteorites and comets. Therefore, the basic building blocks of life have existed on earth virtually from the very beginning. Urey and Miller showed that amino acids can be naturally synthesized in their famous experiment where they ran a spark through an approximation of the earth's ancient atmosphere. It has since been shown the deep sea volcanic vents also generate organic compounds, and the surrounding rocks themselves can act as a template to assemble the organic bits into very complex compounds.
Has enough time elapsed since the earth formed to allow this dilute brew to coalesce into simple cells and eventually complex life? Consider the following 4,560 lines. Each line represents one million years. I’ve color coded them to correspond to important periods or instants of time.

Okay, so what is the point of this little exercise? The point is to show that there has been plenty of time for things to happen on their own without the guiding hand of any manner of deity. To invoke a deity to explain anything exhibits, IMHO, a profound lack of understanding of nature, probability, and an even more profound lack of imagination. Certainly there are circumstances and occurrences that defy scientific explanation. However, to simplistically dub them “an act of God” is merely a game of one-upsmanship, and holds no virtue over the playground taunt of “I know something you don’t know.”
This point of view does not deny the existence of God. God is a metaphysical entity whose existence can be neither proved nor disproved. This perspective does, however, acknowledge that the existence of God is in no way required for life to evolve on this planet. Does it diminish God? Not in the least. In fact as Robert M. Hazen so elegantly pointed out in his book, Genesis: The Scientific Quest For Life’s Origin, those who deny evolution in favor of creationism (currently known as ‘intelligent design theory’) diminish God by relegating God to the gaps in scientific knowledge. As we learn more those gaps will close and so will the space reserved for God by intelligent design proponents.
As Hazen writes, “Isn’t more satisfying to believe in a God who created the whole shebang from the outset – a God of natural laws who stepped back and doesn’t meddle in our affairs? In the beginning God set the entire magnificent fabric of the universe into motion. Atoms and stars and cells and consciousness emerged inexorably, as did the intellect to discover laws of nature through a natural process of self-awareness and discovery. In such a universe, scientific study provides a glimpse of creator as well as creation.”

Goodbye Joy. Goodbye Katherine.
Two of my coworkers died in an automobile accident this weekend. Katherine Johnson and Joy McLean were driving in the mountains on their way from Missoula to Joy’s farm in Idaho. They were caught in a sudden snow storm, lost control of the car, crossed the center line, and were hit by an oncoming car.
Goodbye Katherine. Goodbye Joy. We were hardly what could be called close friends, but I want to thank you both for sharing a small fraction of your life with me. You’ll be missed.
