It’s Funny Until Someone Gets Hurt, then it’s Hilarious

I’ve been amazed at the popularity of Creationism/Intelligent Design among Christian pundits.
Old-earth Creationism accepts the consensus within the field of cosmology about the Big Bang and the formation of the solar system 4.6 billion years ago but rejects evolution. Young-earth Creationism also rejects evolution and argues that the earth is less than 10,000 years old. This view is predominant among evangelical pastors.
Dr. Karl Giberson pointed out an interesting downside of this mindless rejection of science. He begins by citing a Barna survey that lists six reasons why most evangelical Christians disconnect from the church, at least temporarily, after age 15. The most interesting reason: “Churches come across as antagonistic to science.”
Of the young adults surveyed,

  • 23% say they had “been turned off by the creation-versus-evolution debate”
  • 25% say “Christianity is anti-science”
  • 29% say “churches are out of step with the scientific world we live in”
  • 35% say “Christians are too confident they know all the answers”

Ken Ham vs. science
As an example of this rejection of science, Giberson points to the technique recommended to schoolchildren by Creation Museum founder Ken Ham. Ham encourages students to ask, “Were you there?” when the biology teacher says that life on earth appeared roughly 4 billion years ago or the physics teacher says that the Big Bang gave us the universe in its present form 13.7 billion years ago.
Ham proudly blogged about nine-year-old Emma B., who wrote to tell Ham how she attacked a curator’s statement that a moon rock was 3.75 billion years old with “Were you there?”
Biologist PZ Myers nicely deflated Ham’s anti-science question with a gentle reply to Emma B. Myers recommends using instead “How do you know that?” which is a question from which you can actually learn something.
Contrast that with Ham’s “Were you there?” which is designed simply to shut down discussion and to which you already know the answer.
“Were you there?” is a subset of the more general question, “Did you experience this with your own senses?” To Science, this question lost significance hundreds of years ago. The days when Isaac Newton used taste as a tool to understand new chemicals are long gone. Modern science relies heavily on instruments to reliably provide information about nature—from simple ones like compasses, voltmeters, and pH meters to complex ones like the Mars rovers, Hubble space telescope, and Large Hadron Collider.
Personal observation is often necessary (finding new animal species, for example), but this is no longer a requirement for obtaining credible scientific evidence.
William Lane Craig as Hanes Inspector #12
From the standpoint of mainstream Christianity, Ham’s position as a young-earth Creationist and Bible literalist is a bit extreme, but higher profile figures like William Lane Craig also grant themselves the privilege of picking and choosing their science. Craig uses science a lot—at least, when it suits his purposes. The Big Bang suggests a beginning for the universe, so he takes that. Evolution suggests that life on earth didn’t need God, so he rejects that bit.
He imagines that he’s Hanes Inspector Number 12: “It’s not science until I say it’s science.” It may be fun to pretend that, but what could possibly make you think that’s justifiable?
That reminds me of a joke

Scientists figure out how to duplicate abiogenesis (the process by which molecules became something that could evolve). They are so excited that they email God to say they want to show him. So God clears some time on his calendar and has them in.
“Sounds like you’ve been busy,” God said. “Show me what you’ve got.”
“Okay—first you take some dirt,” said one of the scientists.
“Hold on,” God said. “Get your own dirt.”

And to William Lane Craig’s pontificating about science, I say, “Hold on—get your own science.”
As a layman, you either play by the rules of science and accept the scientific consensus whether it’s compatible with your preconceptions or not, or you sit at the children’s table. If you want to hang out with the adults, you can’t invent reasons to rationalize why this science is valid and that is not.
There are consequences
Evangelicals may want to rethink this picking and choosing of science. Giberson ends his article:

The dismissive and even hostile approach to science taken by evangelical leaders like Ken Ham accounts for the Barna finding above. In the name of protecting Christianity from a secularism perceived as corrosive to the faith, the creationists are unwittingly driving the best and brightest evangelicals out of the church. … What remains after their exodus is an even more intellectually impoverished parallel culture, with even fewer resources to think about complex issues.

Perhaps I should be more welcoming to Christian anti-science in the future.

No man ever believes that the Bible means what it says;
he is always convinced that it says what he means.

F-ing Magnets—How do THEY Work?

The hip hop band Insane Clown Posse created an interesting meme with its 2010 song “Miracles.”
Well, not so much interesting as bizarre. Here’s a bowdlerized version of the verses in question:

Water, fire, air and dirt.
F**kin’ magnets, how do they work?
And I don’t wanna talk to a scientist.
Y’all motherf**kers lying and getting me pissed.

You really want to know how magnets work? Here you go:

These are Maxwell’s equations, the foundation of our understanding of electricity and magnetism. They were published in 1865. A deep understanding would obviously take some effort, but the point is that this question is no mystery to science.
The song’s not all bad, but it wanders from justifiable wonder at nature (“Oceans spanning beyond my sight / And a million stars way above ’em at night”) to conflating wonder with ignorance.
Saturday Night Live did an excellent parody video. The lyrics in their song “Magical Mysteries” include, “Where does the sun hide at night? / Did people really used to live in black and white?” which isn’t too far from denying our knowledge about magnets.
Maybe Bill O’Reilly is a Juggalo (a fan of Insane Clown Posse) because he has sounded a lot like them. In a 2011 interview with David Silverman, president of American Atheists, O’Reilly said, “I’ll tell you why [religion is] not a scam, in my opinion. Tide goes in, tide goes out. Never a miscommunication. You can’t explain that.”
(Or you could just look it up in Wikipedia.)
And were there no consequences to O’Reilly for being this confused about reality? He’s been lampooned for these statements (and a later defense, which was equally ridiculous) by people who weren’t his fans to begin with. But doesn’t his fan base care about reality? Can they possibly cheer on this willful ignorance?
Despite the contrary opinions of O’Reilly and Insane Clown Posse, learning about how things work can make them more amazing. Actually understanding how magnets work doesn’t ruin the magic trick, it turns mysterious into marvelous.
Here’s an experiment: go outside on a clear night. Hold out your hand, arm extended, and look at the nail of your little finger. That fingernail is covering a million galaxies. Not a million stars, a million galaxies. Each galaxy has roughly 100 billion stars. That’s 100,000,000,000,000,000 stars under just one fingernail. Now see how vast the sphere of space is compared to that one tiny patch.
And how does the Bible treat this inconceivable vastness? “[God] also made the stars” (Gen. 1:16). That’s it.
The god of the Old Testament is little more than a dictator with the wisdom of Solomon, the generalship of Alexander, and the physical strength of Hercules. But science gives you the vastness of the universe, the energy of a supernova, the bizarreness of quantum physics, and the complexity of the human body. The writers of the Bible were constrained by their imagination, and it shows. There is so much out there that they couldn’t begin to imagine. If you want wonder, discard the Bible and open a science book.
And this is not groundless myth, it’s science—the discipline that makes possible your reading this across the Internet, on a computer, powered by electricity (and governed by Maxwell’s equations).
Carl Sagan said, “We are star stuff” to suggest that we are literally made from the remnants of stars. Two adjoining carbon atoms in a molecule in your body might have come from different exploding stars. Science gives us this insight, not religion.
Second-century Christian author Tertullian is credited with the maxim, credo quia absurdum (I believe because it is absurd). In other words, no one could make this stuff up.
If you believe things either in spite of evidence to the contrary or because of it, science may not for you. But if you want to understand reality to the best of humanity’s ability, rely on science. C’mon in—the water’s fine!

Science does not make it impossible to believe in God, 
but it does make it possible to not believe in God.

Awe: Which Has More, Science or Christianity?

You may be surprised to learn that not everyone is convinced by the arguments of New Atheism’s Four Horsemen. I certainly was surprised.
In one negative review of Christopher Hitchens’ God is not Great, the author said:

Hitchens claims that, “As in all cases, the findings of science are far more awe-inspiring than the rantings of the godly.”
Is he serious? I doubt that even Hitchens would find re-runs of Carl Sagan’s Cosmos “far more awe-inspiring” than Michelangelo’s vision of God creating man.

And can this author be serious? He’s saying that the awe from science is dwarfed by that from religion?
Science in Palestine
Here’s a brief caricature of what I imagine “awe” meant in the Old Testament. Imagine a Jew and a non-Jew meet 3000 years ago in Palestine. They’re comparing gods.
Jew: And strong! Let me tell you how strong Yahweh is. See that rock over there? The one as big as a house?
Not-a-Jew: Okay.
Jew: Yahweh could pick it up and throw it just like you’d throw a pebble.
NJ: Wow!
Jew: Yeah, and that mountain over there? He could pick it up and move it across the valley without even trying.
NJ: Impressive.
Jew: And did I tell you that he created everything? And I mean everything! This was thousands of years ago—he formed all the land from the Mediterranean to Mesopotamia; from Egypt to Greece. He created the sun and moon. Rainbows, earthquakes—everything!
NJ: I didn’t know that …
Jew: Yeah, so don’t mess with us ’cause he’s on our side.
Yahweh was like a superhero—stronger than Hercules, with better generalship than Alexander, and wiser than Solomon. The Jews needed a big brother to help with all their difficulties with neighboring tribes and countries. It’s nice to have a superhero on your side when there are bullies around (who each have their own superhero protectors).
The imagination of a primitive desert tribe 3000 years ago wasn’t that broad, and that superhero concept of God was about as much as they could imagine.
… vs. science today
Compare that with what modern science has given us in the past couple of hundred years. Let’s ignore the advances that make our lives much more bearable (vaccines, antibiotics, anesthesia, energy, transportation, engineering, etc.) and focus on the cerebral stuff. The mind-expanding stuff. Things like the age of the earth and the universe, the huge distances between stars and galaxies, or the amount of energy stars produce.
Try this experiment: on a clear night, go look at the stars. Now extend your arm and spread your fingers. The nail of your little finger covers one million galaxies. In each galaxy are on average 100 billion stars. This gives a good perspective on the tiny space our earth occupies in the universe.
Or look at the small scale and consider the complexity of a cell. If you think evolution is counterintuitive, consider quantum physics–quantum entanglement, for example.
And notice the irony in the author’s “I doubt that even Hitchens would find re-runs of Carl Sagan’s Cosmos ‘far more awe-inspiring’ than Michelangelo’s vision of God creating man.” Yes, the Sistine Chapel fresco is marvelous, but it was created by a man! Can he be saying that a work of a man trumps nature’s marvels?
The author lists other great works inspired by religion: “Giotto, Bach and Handel, Chartres and St. Peter’s.” Art, music, and architecture—here again, these are all made by humans.
Who, exactly, do you give praise to?
I can’t resist an aside on the topic of what God does vs. what people do. You’ve probably seen the iconic woman who survived the big disaster (hurricane Katrina’s rampage through New Orleans, for example) and is now back on her feet. “Thank you Jesus!” she says. “I lost everything, but now I have clothes and an apartment and a job.”
She seems to forget that Jesus didn’t lift a finger to give her those things—she’s doing well thanks to other people. Her thanks should be aimed at the combination of government aid and charitable donations that helped her out. And while we’re talking about Jesus, he was the guy who brought the disaster in the first place. What she should have said was “Thank you America! And Jesus, we need to talk …”
Of course, this doesn’t address the “Does God exist?” question. Maybe God does exist, and he produced the amazing things we see in nature. But it’s through science that we see these awe-inspiring things, not through the Bible. This marvelous universe is not at all what the early Jews, living on their small Mesopotamian disk of a world with the sun rotating around it, imagined it to be.
The awe we get from religion can’t compare to the awe we get from science.

If God had wanted us to believe in him,
he would have existed.

Human Memory: Vivid Doesn’t Mean Accurate

Apologist Frank Turek gives the 9/11 attack as an example of a vivid memory. Can you remember where you were and what you were doing on September 11, 2001? How about the same date a year earlier? Why is one date memorable and the other not? And what does this tell us about the accuracy of the gospel record of the remarkable life of Jesus?
Important events impress themselves on our memories, but there’s a big difference between a vivid memory and an accurate one. “This American Life” provided a great example a few weeks ago of how our memories fool us—a startling example, in fact. Let me briefly summarize it.
Emir’s story
Emir Kamenica was born in Bosnia in 1978. Yugoslavia began to unravel when he was 13. Though his father was killed, the rest of the family was lucky to get out of the war and make it as refugees to Atlanta.
Their new life was no paradise. Their apartment was dirty, and Emir made no friends. He was one of a couple of dozen white kids out of 900 in his high school. He felt the racial tension both in his neighborhood and his school. His English was terrible, and he practiced by translating passages from his favorite book, The Fortress, into English.
The one bright light in his school experience was Miss Ames, a student teacher in his English class for only a couple of weeks.
For one assignment in her class, Emir took a shortcut by submitting a translated passage from The Fortress that he found especially moving. The book was in Bosnian—who would find out? Miss Ames was impressed and said that he needed to get to a better school. By good fortune, she had a job interview at a local private school in a few days, and she took him along.
To Emir, the school was paradise. He had practiced a short line: “I’m a Bosnian refuge. My school is really bad. Please, can I go here?” For her own interview, Miss Ames had brought his essay as an example of what inspired her to be a teacher.
Though student applications were due months earlier and financial aid for that year was already arranged, the school highly valued diversity, and a Bosnia refugee would be a nice addition to the student body. Strings were pulled, and Emir made it in. After graduating there, he went on to Harvard as an undergrad. Then he earned a PhD from Harvard. And now, at 35, he’s a professor of Behavioral Economics at the University of Chicago.
This Bosnian refugee became a success all because one teacher took the time to help him out, fooled by his plagiarized essay. She mistook him for a genius and got him into a private school, which got him into Harvard, which launched a successful academic career.
This was Emir’s defining story, and he told it over and over. He contrasted it with that of his one friend from public school, a fellow Bosnian, who had no guardian angel. The friend got into trouble, spent time in jail, and went back to Bosnia.
Miss Ames didn’t get the job, and Emir never saw her again. As an adult, he tried to find her a couple of times, without success. He didn’t know her first name and wasn’t even sure of the spelling of her last name.
… the other side of the story
“This American Life” hired a private detective and found Miss Ames. Her version of the story was … different.
She had been a new teacher but wasn’t an intern. In fact, she had been Emir’s full-time teacher for an entire semester. His English was “tremendous,” and, in talking to his other teachers, Miss Ames realized that this sophomore was beyond senior level in all subjects.
She also disagreed about the character of the school. It wasn’t a ghetto school but had a great mix of students, like a teenage UN. She remembered about 20% white kids (later confirmed by fact checking).
And the essay that Emir plagiarized, the central fact to Emir’s story? She didn’t even remember it. It played no role in her decision to push him into the private school.
Emir never saw Miss Ames at the new school, not because she didn’t get the job, but because that trip had never been for a job interview. It had all been for him.
After Emir, Miss Ames’ story took a bad turn. The school administration was annoyed that she had poached their prize pupil, and they exiled her to whatever amounted to Siberia in that school district. After another year, she quit teaching.
(I’ve written more about our fallible brains here.)
The punch line of her story was that Emir had been any teacher’s once-in-a-lifetime student. He could’ve still gotten a great education if he’d stayed at that public high school, been at the top of his class at a good regional college, and then gone to Harvard for the PhD. After leaving Atlanta, she didn’t keep track of his career except by looking for his name in the Nobel Prize list every year.
For both people, but Emir in particular, these stories weren’t incidental but were important stories in their lives. His story was of plagiarism, luck, and a guardian angel. Her story was of innate gifts, inevitability, and martyrdom.
That doesn’t mean that Emir’s story wasn’t vivid–it was. It also doesn’t prove that it was false. What it proves is that at least one story was false.
A vivid memory may not be an accurate one. Remember that the next time someone points to the gospels and insists that so remarkable a story as the resurrection must’ve been remembered accurately despite the long decades from events to first writing.

How Science Works (and How Christianity Thinks it Wins)


This argument was made at a Creationism conference that I attended several years ago: science isn’t trustworthy because every time you turn around, it’s changing its mind.

  • The sun goes around the earth … no, wait a minute—it’s the other way around.
  • Here’s the fossil of an early human … no, hold on—that one’s a hoax.
  • Living things hold a special energy or force—an élan vital—that animates them … nope, that’s passé.
  • Every wave needs a medium, so space must be filled with “ether” for light to propagate through … oops, wrong again.

An early theory of the formation of the moon said that the fast-spinning early earth flung out the moon and that the big circular Pacific Ocean basin is where it came from. The question of origin of the moon has been an active area of research, and the flung-out-moon idea is just another discarded scientific theory—this was one of the areas of research that was lampooned at this conference.
The Creationist argues that when you turn from changeable Science to Christianity’s unchanging God and Bible, you have something solid that you can trust.
How does science change?
Science does change, but let’s notice that the size of any change tends to decrease for a single theory. When the door is flung open to a new field of inquiry—say by Leeuwenhoek’s discovery of single-celled organisms or Galileo’s use of the telescope—new theories based on insufficient evidence try to organize the chaos. One theory might quickly supersede another, but as theories become better at explaining more, changes becomes smaller. Here are some examples.

  • Geocentrism to heliocentrism was an enormous change for the model of the solar system. Our understanding of the solar system continues to change (new theories about why Uranus is tipped on its side or the reclassification of Pluto as a dwarf planet, for example), but these are comparatively minor.
  • Evolution revolutionized biology, and the changes in biology today are merely refinements to this theory. Punctuated equilibrium proposes occasional rapid change instead of Darwin’s view of gradual change, but it tries to improve evolution, not overturn it.
  • The intuitive flat earth model was replaced by a spherical earth, and the observation that it’s actually not spherical but slightly flattened at the poles is a small change.
  • Quantum physics continues to change, but new discoveries are not likely to say that matter is not made up of atoms, which are themselves not made up of protons, neutrons, and electrons.

Christians eager to paint the Bible as an unchanging rock in a sea of chaos don’t seem to understand that they point to science’s strength. Science realizes that new discoveries may obsolete old theories, and every scientific statement is provisional. And, remarkably, science is self-correcting. It finds its own errors.
Science changes, and that’s its strength. The Bible never changes, and that’s its weakness.

When people thought the Earth was flat, they were wrong.
When people thought the Earth was spherical they were wrong.
But if you think that thinking the Earth is spherical
is just as wrong as thinking the Earth is flat,
then your view is wronger than both of them put together.

How Do We Know the Moon ISN’T Made of Green Cheese?

In a fable going back centuries within various cultures, a simpleton sees the reflection of the full moon in water and imagines that it’s a wheel of green (that is, unaged) cheese. It’s a tale that we often pass on to our children and that we discard with time, like belief in the Easter Bunny.
But how do you know that the moon isn’t made of green cheese?
Physicist Sean M. Carroll addressed this question in a lecture. After a few moments exploring physical issues like the moon’s mass, volume, and density and the (dissimilar) density of cheese, he gave this frank broadside:

The answer is that it’s absurd to think the moon is made of green cheese.

He goes on to say that we understand how the planets were formed and how the solar system works. There simply is no reason to suppose that the moon is made of green cheese and plenty of reasons to suppose that it’s not.

This is not a proof, there is no metaphysical proof, like you can prove a statement in logic or math that the moon is not made of green cheese. But science nevertheless passes judgments on claims based on how well they fit in with the rest of our theoretical understanding.

Let’s apply this thinking to the domain of this blog. To take one supernatural example, how do we know that Jesus wasn’t raised from the dead? The answer is the same: it’s absurd to think that Jesus was raised from the dead.

  • We know how death works. We see it in plants and animals, and we know that when they’re gone, they’re just gone. Rats don’t have souls. Zebras don’t go to heaven. There’s no reason to suppose that it works any differently for our favorite animal, Homo sapiens, and plenty of reasons to suppose that it works the same.
  • We know about ancient manuscripts. Lots of cultures wrote their ancient myths, and many of these are older than the books of the Old Testament: Gilgamesh (Sumerian), Enûma Eliš (Babylonian), Ramayana (Hindu), Iliad (Greek), Beowulf (Anglo-Saxon), Popol Vuh (Mayan), and so on. Bible stories appear to have been lifted from earlier stories from neighboring cultures–the Garden of Eden, global Flood, and Jesus resurrection stories, for example. For whatever reason, people write miracle stories, and we have a large and well-populated bin labeled “Legend” in which to put stories like those in the Bible.
  • We know that stories and legends can grow with time. We may have heard of Charles Darwin’s deathbed conversion to Christianity (false). Or that a decent fraction of Americans thought that President Obama is a Muslim. Or that aliens crash-landed in Roswell, New Mexico. Or that a new star appeared in the night sky with the birth of North Korea’s Kim Jong Il. In our own time, urban legends so neatly fit a standard pattern, that simple rules help identify them. The Principle of Analogy is helpful here: if it looks like yet another legend (for example), that’s a good assumption to start with.
  • We know that humans invent religions. There are 42,000 denominations of Christianity alone, for example, and uncountably many versions of the myriad religions invented through history. There is little reason to imagine that Christianity is the one exception that is actually true.

Natural explanations are sufficient to explain Christianity.
Might the moon actually be made of cheese? Science doesn’t make unconditional statements, but we can assume the contrary with about as much confidence as we have in any scientific statement.
Might Jesus have been raised from the dead? Sure, it’s possible, but that’s not where the facts point. Aside from satisfying a preconception, why imagine that this is the case?

When a religion is good, I conceive it will support itself;
and when it does not support itself, and God does not take care to support it
so that its professors are obliged to call for help of the civil power,
‘tis a sign, I apprehend, of its being a bad one.
