According to LiveScience.com, two geneticists, Alexei Sharov and Richard Gordon, recently applied Moore’s Law to the evolution of life. Moore’s Law is simply the observation that computers have increased in complexity at a roughly steady rate since the first mircrochip was invented. Sharov and Gordon applied that same rate to the evolution of life and extrapolated backwards in an attempt to determine when life began.
Now consider for a moment the assumption behind this calculation: the rate at which organic life increases in complexity through entirely random mutations is equal the rate at which computers increase in complexity through the intelligence of engineers and technicians. Surely this is a conservative assumption, to say the least!
Nevertheless, even though Sharov and Gordon were operating on the assumption that organic life increases in complexity at the rate of intentional design, they still ran out of time! Human beings are so complex that even if we evolved at this breathtaking speed, these two geneticists calculate that about 10 billion years must have elapsed since life first emerged.
Now this is a bit of a problem, since our little planet is only 4.5 billion years old.
Might life therefore be a miracle? Might our existence be evidence of a divine Creator? Not according to these scientists. Sharov and Gordon have another explanation: life hitchhiked to Earth on asteroids from outer space. Seriously. They write,
Contamination with bacterial spores from space appears the most plausible hypothesis that explains the early appearance of life on Earth.
Sure it does.
It was difficult enough to believe that life appeared when lighting struck a “primordial soup” on ancient Earth, but now we have to believe that this life formed on a barren rock hurtling through space at cryogenic temperatures, steadily evolving for 5.5 billion years before it conveniently collided with a habitable planet – and survived the impact.
Now the Bible never says precisely how God created the first cell, how long it took him to do it, or where he put it when he was finished, so my religious commitments do not prevent me from believing in Sharov and Gordon’s hypothesis. However, my religious commitments do not prevent me from believing in leprechauns either.
