How Did Life Begin?

My last blog remarked on the fact that Richard Dawkins, one of the world's leading atheists, now believes in the possibility of "intelligent design." Dawkins is quite willing to grant that life may have originated on earth not by evolution nor by some chance combination of chemicals. He knows how infinitesimal are the odds of random chemicals simply mixing together to produce, say, the first cell. Even the simplest cell is more complicated than the most elaborate human inventions, such as the jet airplane or the most advanced computer. Consequently Dawkins told Ben Stein that maybe smart aliens deposited life on earth. I call this the ET explanation. Intelligent design is okay with Dawkins as long as that intelligent design does not involve a supernatural creator.

Some atheists on this blog are not happy with Dawkins' ET explanation. They want to go back to the early twentieth-century view that somehow the chemicals must have assembled together to produce the first cells. And the favorite piece of evidence is the 1953 experiment conducted by Harold Urey and Stanley Miller. Urey and Miller were operating on Darwin's hopeful assumption that perhaps life originated accidentally in some "warm little pond." They mixed together various chemical compounds, including hydrogen, ammonia, methane and water. To their delight they were able to generate organic compounds, including a small tincture of amino acids.

For a decade or so this generated enormous excitement in the scientific community. But then two things happened to take the wind out of the Urey-Miller balloon. First, scientists found that the early conditions on earth were nothing like the ones that Urey and Miller envisioned. For one, there was virtually no oxygen on the earth in its early stages. So even if chemicals somehow came together to produce organic compounds and amino acids, they could not have done so in anything like the way that Urey and Miller showed.

Second, biologists seeking to try and create life in the laboratory discovered that the really difficult thing is not producing amino acids. It is converting those amino acids into proteins. Here is where things get really complicated, and here is where chance really collapses as a reasonable explanation. For the details I direct you to Franklin Harold's scholarly yet accessible The Way of the Cell. Harold notes that as a consequence of the two developments listed above, the Urey-Miller experiments are now largely dismissed as a viable hypothesis of life's origin. And of course knowledgeable atheists like Dawkins and Francis Crick know this, which is why they have fled to the ET explanation--an explanation that would seem to require at least as much faith as believing in divine creation.

If you enjoy seeing atheist arguments exploded in this way--or even if you're an atheist with masochistic tendencies--you may want to attend one of my "God v. Atheism" debates this week. On Monday, April 21 I'll be debating philosopher Walter Sinnott-Armstrong at Dartmouth College. The debate is at 8 pm in Alumni Hall on the Dartmouth campus. On Tuesday, April 22 I'll be debating Dan Barker, head of the Freedom from Religion Foundation, at Harvard. The debate is at Memorial Church, 1 Harvard Yard, at 8 pm. Finally on Friday April 25 I debate the controversial philosopher Peter Singer at Biola University. The debate is at Chase Gymnasium on the Biola campus near Los Angeles. You can get tickets at the door or at apologeticsevents.com.
