Study: the early Earth’s atmosphere contained oxygen

5 Comments

Here’s a paper published in the prestigious peer-reviewed science journal Nature, entitled “The oxidation state of Hadean magmas and implications for early Earth’s atmosphere”. This paper is significant because it undermines naturalistic scenarios for the origin of life.

Evolution News explains what the paper is about.

Excerpt:

A recent Nature publication reports a new technique for measuring the oxygen levels in Earth’s atmosphere some 4.4 billion years ago. The authors found that by studying cerium oxidation states in zircon, a compound formed from volcanic magma, they could ascertain the oxidation levels in the early earth. Their findings suggest that the early Earth’s oxygen levels were very close to current levels.

[…]Miller and Urey conducted experiments to show that under certain atmospheric conditions and with the right kind of electrical charge, several amino acids could form from inorganic compounds such as methane, ammonia, and water. Several experiments have been done using various inorganic starting materials, all yielding a few amino acids; however, one key aspect of all of these experiments was the lack of oxygen.

If the atmosphere has oxygen (or other oxidants) in it, then it is an oxidizing atmosphere. If the atmosphere lacks oxygen, then it is either inert or a reducing atmosphere. Think of a metal that has been left outside, maybe a piece of iron. That metal will eventually rust. Rusting is the result of the metal being oxidized. With organic reactions, such as the ones that produce amino acids, it is very important that no oxygen be present, or it will quench the reaction. Scientists, therefore, concluded that the early Earth must have been a reducing environment when life first formed (or the building blocks of life first formed) because that was the best environment for producing amino acids. The atmosphere eventually accumulated oxygen, but life did not form in an oxidative environment.

The problem with this hypothesis is that it is based on the assumption that organic life must have formed from inorganic materials. That is why the early Earth must have been a reducing atmosphere. Research has been accumulating for more than thirty years, however, suggesting that the early Earth likely did have oxygen present.

[…]Their findings not only showed that oxygen was present in the early Earth atmosphere, something that has been shown in other studies, but that oxygen was present as early as 4.4 billion years ago. This takes the window of time available for life to have begun, by an origin-of-life scenario like the RNA-first world, and reduces it to an incredibly short amount of time. Several factors need to coincide in order for nucleotides or amino acids to form from purely naturalistic circumstances (chance and chemistry). The specific conditions required already made purely naturalist origin-of-life scenarios highly unlikely. Drastically reducing the amount of time available, adding that to the other conditions needing to be fulfilled, makes the RNA world hypothesis or a Miller-Urey-like synthesis of amino acids simply impossible.

So here’s where we stand. If you are a materialist, then you need a reducing environment on the early Earth in order to get organic building blocks (amino acids) from inorganic materials. However, the production of these organic building blocks (amino acids) requires that the early Earth atmosphere be oxygen-free. And the problem with this new research, which confirms previous research, is that the early Earth contained huge amounts of oxygen – the same amount of oxygen as we have today. This is lethal to naturalistic scenarios for creating the building blocks of life on the Earth’s surface.

Other problems

If you would like to read a helpful overview of the problems with a naturalistic scenario for the origin of life, check out this article by Casey Luskin.

Excerpt:

The “origin of life” (OOL) is best described as the chemical and physical processes that brought into existence the first self-replicating molecule. It differs from the “evolution of life” because Darwinian evolution employs mutation and natural selection to change organisms, which requires reproduction. Since there was no reproduction before the first life, no “mutation – selection” mechanism was operating to build complexity. Hence, OOL theories cannot rely upon natural selection to increase complexity and must create the first life using only the laws of chemistry and physics.

There are so many problems with purely natural explanations for the chemical origin of life on earth that many scientists have already abandoned all hopes that life had a natural origin on earth. Skeptical scientists include Francis Crick (solved the 3-dimensional structure of DNA) and Fred Hoyle (famous British cosmologist and mathematician), who, in an attempt to retain their atheistic worldviews, then propose outrageously untestable cosmological models or easily falsifiable extra-terrestrial-origin-of-life / panspermia scenarios which still do not account for the natural origin of life. So drastic is the evidence that Scientific American editor John Horgan wrote, “[i]f I were a creationist, I would cease attacking the theory of evolution … and focus instead on the origin of life. This is by far the weakest strut of the chassis of modern biology.”3

The article goes over the standard problems with naturalistic scenarios of the origin of life: wrong atmosphere, harmful UV radiation, interfering cross-reactions, oxygen levels, meteorite impacts, chirality, etc.

Most people who are talking about intelligent design at the origin of life talk about the information problem – how do you get the amino acids to form proteins and how do you get nucleotide bases to code for amino acids? But the starting point for solving the sequencing problem is the construction of the amino acids – there has to be a plausible naturalistic scenario to form them.

I would like to describe a situation that arises frequently that concerns me. The situation I describe below brings out a flaw I see in the way that rank-and-file Christians respond to criticisms of Christianity in the public square.

Here is the situation

Eve is busy programming away at her desk, rushing to check in her unit tests so she can spend her lunch hour reading the latest Stephenie Meyer novel, or check on the schedule for her local sports team, “the Vicariouses” (she has tickets for Thursday). Suddenly Eve hears Alice talking to Bob on the other side of her cubicle. She stops typing to listen to the following unencrypted conversation.

Alice: I was watching a documentary on the Discovery Channel last night that said that the universe has always existed, so there is no God!

Bob: I was watching a documentary on PBS last night showing simulations of how the first life started on Earth! God didn’t do it!

Alice: I saw “Inherit the Spin” on the weekend! The only reason people oppose evolution is because of the Bible! Not because of science!

Bob: I’m going to see “The Va Dinci Code” this weekend! It says that the Gospels are unreliable and that Jesus didn’t even die on the cross!

Alice: I just bought the latest Dichard Rawkins book “Christians Should Be Fed to Lions and the Bible Should Be Burned”!

Bob: I will read that as soon as I finish Histopher Chritchens’ book “Why God is the Evilest, Stupidest Person in the World”!

Eve double-majored in business and computer science at the Indian Institute of Technology, and has an MBA from the London School of Economics. She has spent a ton of time, effort and money studying very difficult subjects for her job, and she even publishes research papers. She works full-time and runs her own business part-time, and teaches night classes for a well-known university. She earns about 200K per year. She lives in a huge house, drives an expensive car, and goes on vacation abroad to all the best vacation spots.

Eve thinks she is a Christian. She has attended church since childhood, her husband is a church elder and she sings in the church choir. She reads the Bible and prays every night, because it helps her to get sleepy before bed. She gives lots of money to the poor. She teaches Sunday school to very small children.  She has even read all of the Narnia novels five times! She even has a calendar filled with nature scenes and itsy-bitsy, teeny-weeny Bible verses posted on her office wall at work! Judging from all of these facts, you might expect Eve to get in on that conversation with Alice and Bob, and set them straight.

But she won’t. Why not?

Why won’t Eve stand?

I am wondering if anyone can explain to me why it is that most church Christians are not able or not willing to make a public defense when God’s reputation is called into question. It seems to me that there are two bad effects that follow from Eve’s unwillingness to stand up and invite Alice and Bob to lunch so that she can address their questions and concerns.

  1. God’s reputation is being trashed by Alice and Bob on the basis of lies they’ve swallowed from pop culture. These lies about God’s existence and character could be easily corrected with a minimal amount of study, which Eve is capable of – she is a genius and has amazing entrepreneurial skills.  If someone said similar lies about her husband or children, she would speak up, but she won’t speak up for God.
  2. Alice and Bob are bound for Hell unless someone cares enough to correct their mistaken beliefs, which, along with their sinfulness, is what is keeping them from a relationship with God that would go on in Heaven. If Eve’s husband or children were mistakenly about to drink poison thinking it was Aspirin, then Eve would speak up. But to save her co-workers from Hell, she won’t speak up.

Eve is capable of studying to defend the faith, because of her great success in other areas where so much time and effort were required to master difficult material. So why has she not applied herself to answering public challenges to her Christian faith from her professors, teachers, actors, the media, politicians, scientists, historians, etc.? She’s heard these questions about God’s existence and character all through high school and into university and then now in her career. Doesn’t she believe the Bible when it says to prepare a defense? Doesn’t she believe the Bible when it says to acknowledge God before men? Doesn’t she believe the Bible when it says that all authentic believers in Jesus will suffer a little for their faith?

It seems to me that if she did spend some time studying, and then made her defense to her co-workers, then two good things would follow:

  1. Eve would be demonstrating her love for God and her friendship with God by protecting his reputation when it is called into question by unbelievers in public settings. That’s what friends do – if Eve wanted to be God’s friend, she would care that no one believed lies about him and told lies about him in public settings.
  2. Eve would be demonstrating her love for her neighbor if she was able to correct some of these false beliefs, such as that the universe is eternal, or that a historical case cannot be made for the resurrection, or that evil is not compatible with theism. It’s important for Alice and Bob to know that Christianity is not stupid.

So why is it that Eve is able to go to church for 20 years, sing in the choir, read the Bible, read the Narnia stories, pray on her knees, and yet still be unwilling to do the best thing for God and the best thing for her neighbor?

Questions for my readers

Can anyone help me to understand why Christians are willing to accept this? Why is this not being addressed by churches?

Do you have an experience where a Christian group stifled apologetics? Tell me about that, and why do you think they would do that, in view of the situation I outlined above? My experience is that atheists (as much as I tease them) are FAR more interested in apologetics than church Christians – they are the ones who borrow books and debates, and try to get their atheist wives to go to church after they becomes interested in going to church. Why is that?

I’m not saying we all have to be geniuses. I am just saying that we should put as much effort into learning apologetics as we put into learning school stuff and work stuff.

Note: I picked these names because there is a running gag in computer network security where these names are used to describe the actors. Eve is the eavesdropping hacker, get it?

Review of evidential apologetics book by pastor shows where church needs to improve

Leave a comment

There are basically two views of faith in Christianity.

The first view of faith is the Biblical view of faith as active trust in propositions we know to be true, because we have reasons and evidence to believe those propositions. This view is not only rooted in the Bible, but it extends through Augustine and Aquinas to the present day. I have written about this view of faith before, and quoted many theologians in support of it. I also showed how people in the Bible use miracles as a sign in order to convince skeptics. For example, Peter appealing to the resurrection in Acts 2. The Bible teaches that faith is active trusting based on evidence.

The second view is blind faith. This view is nowhere in the Bible, and this view asserts that becoming a Christian is a leap-of-faith in the dark against all the evidence. This view not only minimizes evidence, but it actually opposes presenting evidence to unbelievers and skeptics in the way that the Bible teaches. This view is nowhere in the Bible, and it was not the method used by Jesus or his followers. It is an unBiblical way of viewing faith, but it is very popular in some circles of Christianity. It is also popular among atheists, because this is what many Christian leaders and pastors tell them that faith is. Why would these Christian leaders reject the plain teaching of the Scripture on faith, and adopt a man-made view of evangelism that opposes the use of evidence?

Well, I have an idea why, based on my experiences trying to get apologetics into the church and university. Suppose a pastor or campus group leader wants to avoid having to learn physics and cosmology, or the minimum facts case for the resurrection, or how to respond to apparently gratuitous suffering, or the problem of religious pluralism. Suppose he thinks that Christianity, if it is about anything, is about his feeling happy and comfortable with a minimum of effort and work. So, he diligently avoids reading apologetics, because learning evidence is hard work. He avoids watching debates on God’s existence and the resurrection, because this is hard work. He avoids conversations with people who do study these things, and implies that there is something wrong with them for studying these things. He endeavors to conceal his laziness and ignorance and cowardice from his flock with much pious God-talk and fervent praise-hymn-singing.

Eventually, some member of his church asks him to go for lunch with an actual non-Christian family member. The pastor agrees and when he meets the unbelieving family member, he has nothing at all to say about typical challenges that unbelievers face. He has no knowledge of evolution, the problem of evil, the hiddenness of God, or the hallucination theory. He has never read a single atheist, and never read a single piece of evidence to refute them from Christian scholars. He lacks humility, refusing to admit that other Christian scholars may know more than he does because they have studied other areas. Needless to say, he fails to defend God’s reputation to the non-Christian. What will he say to the members of his flock about his failure? How will he justify his obstinate refusal to do what everyone else in the Bible does when confronting non-believers?

Well, consider this review of a recent book that defends the Gospels and the historicity of the resurrection by one such fideist pastor.

He writes:

There are, however, two significant shortcomings to the book.

First, Cold-Case Christianity places far too much emphasis on the role of extrabiblical sources. No doubt there is a legitimate role for biblical archaeology and extrabiblical writing from antiquity. Christianity is, after all, a faith firmly rooted in human history. But there is a grave danger when truth is suspended because of an apparent lack of corroboration from extrabiblical sources. And Wallace, I’m afraid, wanders too close to this dark side of apologetics.

All of chapter 12, for instance, is devoted to proving the Gospels have external corroborative evidence—“evidence that are independent of the Gospel documents yet verify the claims of the text” (183). Wallace then addresses the historicity of the pool of Bethesda and makes another worrying statement: “For many years, there was no evidence for such a place outside of John’s Gospel. Because Christianity makes historical claims, archaeology ought to be a tool we can use to see if these claims are, in fact, true” (201-202, emphasis added).

In other words, Wallace seems to suggest we cannot affirm the truth of the Gospel accounts without the stamp of approval from archaeology and other extrabiblical sources. Such reasoning is dangerous, not least because it cannot affirm the inerrancy of the Bible. But also, it places the final court of appeal in the realm of extrabiblical sources rather than of God’s all-sufficient, all-powerful Word.

That is a textbook definition of fideism – that belief is somehow more pious and praiseworthy the less evidence we have. And the best way to have less evidence is to study nothing at all, but to just make a leap-of-faith in the dark. Of course, a leap-of-faith can land you anywhere – Islam, Mormonism. Presumably this pastor is like the Mormons who eschew all evidence and prefer to detect the truth of Mormonism by “the burning of the bosom” which happens when people read the all-sufficient, all-powerful Book of Mormon. His view of faith is identical to theirs, and 180 degrees opposed to the Bible. He has made his leap-of-faith, and that leap-of-faith is not accountable to arguments and evidence. His faith is private and personal, based on his own feelings. He considers it blasphemous to have to demonstrate what he believes to those who disagree with him. Where is this in the Bible? It’s nowhere. But it is everywhere in anti-intellectual Christian circles.

There is a good response to this blind-faith pastor on Deeper Waters. Much less angry than my response.

Excerpt:

The dark side of apologetics? Did I somehow step into a Star Wars universe?

Yes. How horrible to show that the Bible is backed up by sources outside of it. How terrible to show that these events did not happen in a vacuum. Thankfully, no one in the Bible took this approach.

Except for the fact that when the gospel was being preached, there were no gospels per se and there were no epistles. Paul told Agrippa that the events done weren’t done in a corner. In other words, investigate the claims for yourself! The early testimony was eyewitness testimony. Sources like Tacitus and others show the eyewitnesses were right! This was not done in a corner! This was done out in the open! Archaeology helps us confirm the biblical writings and shows that unlike the pagan myths, these events were rooted in a place and time. Is there some danger that our faith will be destroyed by outside sources?

It really becomes a fideistic approach. If your worldview is true, you should have no problem putting it to the strictest scrutiny. If it is not, then you will have a problem. No Christian should fear further research into what they believe. No Christian should have a problem with extra-biblical sources. Now I do agree there is a problem with stating that EVERYTHING must be backed extra-biblically. I think this is a prejudice we too often have where nothing in the Bible can be considered historical unless it’s verified somewhere else. A gospel account alone could count as a historical claim itself that can be investigated, and indeed is in NT scholarship, but where we can get extra-biblical evidence, I’m all for it.

[…]Christianity is a faith that is rooted in evidences so we should be able to use evidences to demonstrate it. I have often been told by those of the presuppositional bent that the approach is used all the time in the Bible. The problem is I can’t find one. I get told passages like “The fear of the Lord is the beginning of wisdom.” Yes. It is. Wisdom refers to godly living. It doesn’t refer to confirming the gospel to be true. When I look at the apostles in every case, I see them pointing to evidences.

I think that Christians are much better off following the example of authentic Christian pastors like R.C. Sproul, who, in a conference on evangelism, invited Dr. Stephen C. Meyer to present multiple lines of evidence from mainstream science to establish the existence of God. The only reason not to take this approach is laziness, which leads to ignorance, which leads to cowardice. And failure. It is pastors like Pastor Bungle above who are responsible for the great falling away from Christianity that we are seeing when we look at young people. Pastors who pride themselves in refusing to connecting the Bible to the real world, with evidence and with policy analysis, are causing young people to abandon the faith.
