What’s the best naturalistic explanation for the origin of life proposed by atheists?

3 Comments

I just ordered the newest edition of “The Mystery of Life’s Origin“, which is a classic book on the origin of life by pro-design authors. The new edition has several new chapters. It reminded me of my interest in the origin of life when I was a younger man, just starting full-time work with a hot Internet start-up in the big city.

Back then, I liked to listen to debates about the origin of life (e.g. – Walter Bradley versus Robert Shapiro, etc.), as well as lectures and interviews. I ordered tons of academic lectures and debates, especially from Access Research Network. Two of my favorite interviews from ARN featured Dr. Charles Thaxton and Dr. Dean Kenyon.

Let’s start with Charles Thaxton’s interview.

And here are the questions:

1. How did you first get interested in the origin of life?
2. How did you come to write The Mystery of Life’s Origin with Walter Bradley and Roger Olsen?
3. Was there an advantage to having the three of you collaborate on the project?
4. What is the primary argument of your book, The Mystery of Life’s Origin?
5. Have scientists come close to developing a plausible naturalistic explanation to the origin of life or do you still consider the origin of life to be a mystery?
6. Do you see a particular irony in the timing of Stanley Miller’s experiments and the discovery of DNA by Watson and Crick?
7. How does the emergence of modern genetics tie in with the Darwinian scenario of life going from simple to complex?
8. What are the major problems with origin of life simulation experiments?
9. Isn’t it rather impressive that amino acids were produced in the Miller experiments?
10. How close is the development of amino acids to the threshold of life?
11. What are the steps involved in producing proteins from amino acids?
12. Why are amino acids isolated during this process?
13. How can the investigator affect the outcome of a simulation experiment?
14. How did you evaluate the different chemical evolution experiments?
15. Are the initial conditions in the simulation experiments plausible?
16. What did the earth’s early atmosphere contain?
17. Will the simulation experiments work with this atmosphere?
18. There seems to be an underlying assumption that the origin of life resulted without any intelligent input whatsoever yet the simulation experiments appear to rely upon intelligent guidance. Could you comment on this irony?
19. Are there any natural processes that would have filtered out destructive ultraviolet light?
20. What additional steps beyond creating amino acids would be required to develop life?
21. What is so difficult about making proteins or nucleic acids?
22. In addition to the energy problem in protein synthesis isn’t there a sequencing problem?
23. Are DNA sequences analogous to a written language?
24. Has Hubert Yockey made similar claims?
25. In The Mystery of Life’s Origin you refer to order, randomness, and specified complexity. Could you give us an overview of these concepts?
26. What do you think the presence of specified complexity in a living system indicates about its origin?
27. In inferring the necessity of intelligence to produce life haven’t you ventured from the realm of science to religion?
28. Could you summarize the reasons why you believe intelligence was involved in the origin of life?
29. What are the major objections to your current point of view?
30. How was The Mystery of Life’s Origin received by the scientific community?
31. What was Dean Kenyon’s response to your critiques of his book, Biochemical Predestination?
32. What was Dean Kenyon’s response to The Mystery of Life’s Origin?
33. Were you a bit apprehensive about meeting Kenyon after writing a book which was quite critical of his views in Biochemical Predestination?
34. Are self-organizational theories plausible?
35. Would you comment on the work done by Prigogine and Eigen?
36. What is your assessment of RNA scenarios?
37. What other problems do you see with an RNA world?

You can learn more about Charles Thaxton here.

And here’s the interview with Dean Kenyon:

And here are the questions:

1. What first interested you in biology and the origin of life? What is your academic background in this area?
2. What was your viewpoint on the origin of life when you wrote Biochemical Predestination?
3. How have your views on the origin of life changed since you wrote Biochemical Predestination?
4. Do many of your colleagues support your new position? If not, why not?
5. What are the general presuppositions that scientists make who study the origin of life?
6. What is the Oparin-Haldane hypothesis, and what role does it play in current research and teaching on the origin of life?
7. What are the major underlying assumptions of the Oparin (chemical evolution) hypothesis?
8. Are there any other important assumptions in origin of life theories?
9. How well are these assumptions supported by currently available scientific data?
10. What is your evaluation of the Miller type of simulation experiment? What do these experiments tell us about possible chemical events on the prebiotic Earth?
11. Is it possible that interfering cross-reactions might prevent life from arising naturalistically?
12. Stanley Miller’s pioneering work in the origin of life assumed a reducing atmosphere of methane, ammonia, water vapor, and carbon dioxide? Is there sufficient empirical support for this assumption?
15. How large a gap is there between the most complex “protocell” model and the simplest living cell?
16. What is the biologically relevant information content of the simplest living organism known to exist? What are estimates for a theoretical minimum information content of the first living cell?
17. How probable is it that such complexity could arise by undirected chemical processes?
19. What are the major unsolved problems in research on the origin of life?
20. What is the relevance of the Second Law of Thermodynamics to the origin of life?
21. Is it plausible that an “RNA world” was the precursor of the first living cells?
25. If life did not originate by chemical evolution on the primitive Earth, what other possible scientific explanations exist?
26. What do you mean by your statement that “perhaps scientism is more widespread than we like to think”?
27. Is it possible that natural processes are insufficient to account for the origin of all biological information?
28. Can science rule out the possibility that most biological information had an intelligent cause?
29. What alternatives are there to pursuing purely naturalistic explanations for the origin of life?
30. What do you mean by “intelligent design” as it relates to the origin of life?
31. Why is an intelligent design or creationist interpretation of scientific data bearing on origins not acceptable to many scientists?
32. What criteria could be used to determine if the information content of living organisms had an intelligent or natural cause?
34. Does academic freedom allow you to discuss the difficulties of scientific naturalism and origin of life theories? If not, why are they protected from criticism?
35. How should the origin of life be taught in light of the California Science Framework policy which states that “nothing in science or in any other field of knowledge shall be taught dogmatically”?
36. How is scientific progress impacted when critiques of current theories are suppressed?

The challenge for naturalists posed by the origin of life makes it well worth your time to learn and understand. I used to explain this argument to my entire IT department on white boards when I was a young man. It’s fascinating, and more convincing than personal testimonies or abstract philosophical arguments. Although I read books on the origin of life, I learned how to present the information as an argument by watching the interviews above over and over.

People sometimes ask me how I was able to survive 22 years in IT with my theism intact. It turns out that there are no shortcuts to a theistic worldview. You have to support it with evidence. You have to be able to show your work about how you reached your conclusions. I’m a theist today because I never found a single atheist in any software development job who could even begin to challenge the evidence that I collected from listening to all those lectures and debates that I started from in my early 20s. It was as easy to defeat them as taking candy from a baby.

If only Christian parents and Christian leaders understood the importance of scientific facts when they talk to young people about Christianity. We need to be less worried about hurting the feelings of young people by making them “feel dumb”. Christianity isn’t supposed to be easy. It’s not a bad thing to ask people to work hard at learning how to rationally ground your beliefs with evidence. If we want to stop our young people from being lazy, ignorant and cowardly, then the right way to do it is to make them work. Make them learn. Make them fight.

Andy Bannister and Michael Ruse discuss how atheists find meaning in life

4 Comments
Two horses fight it out, may the best horse win!
Two horses fight it out, and may the best horse win!

I’m summarizing a recent episode of the Unbelievable show.

Details:

Atheist philosopher Michael Ruse joins Justin as we spend a second week looking at Andy Bannister’s new book ‘The atheist who didn’t exist’.

Its amusingly titled chapters include ‘The Peculiar Case of the Postmodern Penguin (or: Why Life without God is Meaningless). Michael and Andy debate whether it’s a problem that atheists can’t have meaning with a ‘capital M’.

Here is a summary of the discussion between Ruse and Bannister, and my comments below the summary.

The MP3 file is here.

Summary:

  • Ruse: ultimate questions are serious questions, and some religions are attempting to provide serious answers to those questions
  • Ruse: there is a psychological element to belief in God but it’s not a complete explanation, but it can apply to non-belief as well
  • Bannister: there are psychological reasons why people would prefer unbelief (quotes Thomas Nagel and Aldous Huxley)
  • Bannister: (to Ruse) what do you think would follow next if you got new information that caused you to believe in God?
  • Ruse: I’d feel scared, I’d think of all the reasons that God would dislike me, rather than any reasons why God would save me
  • Bannister: according to the Bible, God is not so much interested in mere belief, but in active trust in him
  • Ruse: without being smug, I just completed 50 years as a college professor of philosophy, and I have a sense of worth from that
  • Ruse: if God turns up, and says that 50 years of being a professor is not good enough, well, I don’t know God, I’m sorry, I did my best
  • Brierley: Andy, explain to us this story of how a penguin explained to you how he invented a subjective meaning in life for himself?
  • Brierley: (reads the story)
  • Bannister: when it comes to reading a book, the real meaning is the meaning the author intended the book to have
  • Bannister: readers can inject their own meaning into the book that has nothing to do with it, but the author gives the real meaning
  • Bannister: meaning in life is like reading a book – you can make up your own meaning, but the author’s meaning is the real meaning
  • Brierley: (to Ruse) on atheism, is there any objective meaning?
  • Ruse: “obviously, someone like myself cannot have meaning with a capital M in that sense”
  • Ruse: the real question is and atheist can find a sense of self-worth, “I find that I’m happier within myself, I can find meaning”
  • Bannister: what would you say to someone who drinks away the family inheritance and gets the same sense of happiness you have?
  • Bannister: what would you say to all the people who are unable to get “a sense of self-worth” from their career, because of where they are born, sickness, etc.
  • Ruse: I have nothing to offer them, some people are born into such awful situations that they are bound to be bad people
  • Ruse: these unfair accidents of birth, etc.,  fits with atheism better
  • Ruse: what we should do is change society so that more people can build a sense of self-worth through achievements
  • Ruse: that way, they can say to God “I used my talents” so they can create feelings of self-worth and happiness (apart from God)
  • Bannister: meaning in life cannot be answered without answering questions related to identity, value, which are rooted in the overall worldview
  • Bannister: on the Christian worldview, you have an infinite worth, your value isn’t determined by circumstances, earnings, friends, etc.
  • Bannister: your value comes from what Jesus was willing to pay to save you, namely, giving his own life for you
  • Bannister: when I travel to meet other Christians in other parts of the world, they have a happiness that should not be there if they are getting happiness from wealth, fame, achievements, etc.
  • Bannister: but when you come to the West, many people who have wealth, fame, achievement, etc. are unhappy
  • Ruse: well maybe who look after a flock of sheep every day may get a sense of self-worth from that, or from other jobs
  • Ruse: I do take Christianity very seriously, it is a grown-up proposal to answer grown-up questions – it works if it is true
  • Ruse: we don’t have to follow Nietzche’s statement that if there is no God, there is no meaning in life – we can find a middle way, we can achieve meaning in life by using our talents to achieve things
  • Bannister: I disagree with Michael, I don’t think that the meaning you invent for yourself is authentic meaning
  • Bannister: distracting yourself with amusing things and happiness is not an answer to the problem
  • Brierley: (to Ruse) are you saying that you have searched for ultimate meaning, and you are settling for subjective meaning?
  • Ruse: my subjective meaning is not second class to objective meaning, “I feel a real deep sense of achievement, of meaning, of self-worth, of having used my talents properly, and I don’t feel in any sense a sense of regret” (what matters to him is how he feels)
  • Bannister: notice how Michael keeps bringing in value judgments. e.g. – “use my talents well”, that implies that there is a right way and a wrong to use your talents, which assumes an objective scale of right and wrong, which makes no sense in atheism
  • Bannister: an atheist can sit in a sun room and enjoy the feelings of happiness generated by the light and heat of the Sun, without asking whether there is a Sun out there
  • Bannister: ultimately, at the end of the day, my concern is not whether something makes me happy or makes me feel fulfilled
  • Bannister: ultimately, at the end of the day, I think there is only one real reason to wrestle with these questions of meaning, and that is to find truth
  • Ruse: sometimes we reach a point where we cannot get to true answers to some questions, sometimes we look for truth, but then give up and confess “I cannot find it” and then move on from there

Is it possible to dispense with God’s advice on your decision-making and achieve something that affects a lot of people, or makes people like you, or makes you famous, etc., and then have that please God? “Look, God, I did something I liked that affected a lot of people, and made them feel happy as they were on their way to Hell because they rejected you”. I think a lot of celebrities, athletes and musicians have feelings that they have achieved something, but having feelings of achievement because you entertain people doesn’t mean anything to God.

So what is the standard? How you imitate Jesus – self-control, self-denial and self-sacrifice to honor God – that is the standard. If I had to choose between giving up two hours of my life to summarize this discussion for my readers, and all the fame and fortune that people who make godless TV shows, movies and music have, I would choose to make this debate summary. My goal in life is not to have fun, thrills, travel and feel happy in this world. I have a Boss. Performing actions that respect the Boss is objectively meaningful. It’s may not seem like much compared to what James Bond does in million-dollar movies, but at least I am wearing the right uniform, and playing for the right team.

I’m starting to notice that a lot of younger Christians are more interested in feeling good, having fun, being liked by others than they are in being able to know what’s true or show what’s true. Christians are no exception to this problem of finding meaning in life. A lot of us are just taking in entertainment and trying hard not to think at all.

New study: model of 700 quintillion terrestrial exoplanets suggests Earth is special

The Circumstellar Habitable Zone, where liquid water could potentially exist
The Circumstellar Habitable Zone, where liquid water could potentially exist

This is from Scientific American. (H/T William)

Excerpt:

More than 400 years ago Renaissance scientist Nicolaus Copernicus reduced us to near nothingness by showing that our planet is not the center of the solar system. With every subsequent scientific revolution, most other privileged positions in the universe humans might have held dear have been further degraded, revealing the cold truth that our species is the smallest of specks on a speck of a planet, cosmologically speaking. A new calculation of exoplanets suggests that Earth is just one out of a likely 700 million trillion terrestrial planets in the entire observable universe. But the average age of these planets—well above Earth’s age—and their typical locations—in galaxies vastly unlike the Milky Way—just might turn the Copernican principle on its head.

Astronomer Erik Zackrisson from Uppsala University and his colleagues created a cosmic compendium of all the terrestrial exoplanets likely to exist throughout the observable universe, based on the rocky worlds astronomers have found so far. In a powerful computer simulation, they first created their own mini universe containing models of the earliest galaxies. Then they unleashed the laws of physics—as close as scientists understand them—that describe how galaxies grow, how stars evolve and how planets come to be. Finally, they fast-forwarded through 13.8 billion years of cosmic history. Their results, published to the preprint server arXiv (pdf) and submitted to The Astrophysical Journal, provide a tantalizing trove of probable exoplanet statistics that helps astronomers understand our place in the universe.

Discover magazine, which is all in for Darwinism and aliens everywhere, says this about the study:

Zackrisson found that Earth appears to have been dealt a fairly lucky hand. In a galaxy like the Milky Way, for example, most of the planets Zackrisson’s model generated looked very different than Earth — they were larger, older and very unlikely to support life.

[…]Zackrisson’s work suggests an alternative to the commonly held assumption that planets similar to Earth must exist, based on the sheer number of planets out there.

[…]One of the most fundamental requirements for a planet to sustain life is to orbit in the “habitable zone” of a star — the “Goldilocks” region where the temperature is just right and liquid water can exist. Astronomers have, to this point, discovered around 30 exoplanets in the habitable zones of stars. Simply extrapolating that figure based on the known number of stars suggests that there should be about 50 billion such planets in the Milky Way alone. Probability seems to dictate that Earth-twins are out there somewhere.

But according to Zackrisson, most planets in the universe shouldn’t look like Earth. His model indicates that Earth’s existence presents a mild statistical anomaly in the multiplicity of planets. Most of the worlds predicted by his model exist in galaxies larger than the Milky Way and orbit stars with different compositions — an important factor in determining a planet’s characteristics. His research indicates that, from a purely statistical standpoint, Earth perhaps shouldn’t exist.

Time for me to list out some of the things that are required for a galaxy, solar system and planet to support complex embodied life. Not just life as we know it, but life of any conceivable kind given these laws of physics.

  • a solar system with a single massive Sun than can serve as a long-lived, stable source of energy
  • a terrestrial planet (non-gaseous)
  • the planet must be the right distance from the sun in order to preserve liquid water at the surface – if it’s too close, the water is burnt off in a runaway greenhouse effect, if it’s too far, the water is permanently frozen in a runaway glaciation
  • the solar system must be placed at the right place in the galaxy – not too near dangerous radiation, but close enough to other stars to be able to absorb heavy elements after neighboring stars die
  • a moon of sufficient mass to stabilize the tilt of the planet’s rotation
  • plate tectonics
  • an oxygen-rich atmosphere
  • a sweeper planet to deflect comets, etc.
  • planetary neighbors must have non-eccentric orbits

It’s not easy to make a planet that supports life. For those who are interested in reaching out to God, he has left us an abundance of evidence for his existence – and his attention to detail.
