Genesis: Revisited (squeezing the round peg of science into the square hole of religion)

Many of us, Christian or not, are familiar with the story of Genesis.  It tells us how the universe, our Earth and it's inhabitants were created.  It is similar to other Mesopotamian creation myths and offers a monotheistic (single god) perspective.  

But should it be taken literally?  Many Creationists will argue that it should. However, Michael Shermer has put forth a revised version of the myth.  Read on to watch a video, and read the transcript.  But first, let's review the story below...

The Story of Genesis


1 In the beginning God created the heavens and the earth. 2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
 3 And God said, “Let there be light,” and there was light. 4 God saw that the light was good, and he separated the light from the darkness. 5 God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning—the first day.
 6 And God said, “Let there be a vault between the waters to separate water from water.” 7 So God made the vault and separated the water under the vault from the water above it. And it was so. 8 God called the vault “sky.” And there was evening, and there was morning—the second day.
 9 And God said, “Let the water under the sky be gathered to one place, and let dry ground appear.” And it was so. 10 God called the dry ground “land,” and the gathered waters he called “seas.” And God saw that it was good.
    11 Then God said, “Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds.” And it was so. 12 The land produced vegetation: plants bearing seed according to their kinds and trees bearing fruit with seed in it according to their kinds. And God saw that it was good. 13 And there was evening, and there was morning—the third day.
 14 And God said, “Let there be lights in the vault of the sky to separate the day from the night, and let them serve as signs to mark sacred times, and days and years, 15 and let them be lights in the vault of the sky to give light on the earth.” And it was so. 16 God made two great lights—the greater light to govern the day and the lesser light to govern the night. He also made the stars. 17 God set them in the vault of the sky to give light on the earth, 18 to govern the day and the night, and to separate light from darkness. And God saw that it was good. 19 And there was evening, and there was morning—the fourth day.
 20 And God said, “Let the water teem with living creatures, and let birds fly above the earth across the vault of the sky.” 21 So God created the great creatures of the sea and every living thing with which the water teems and that moves about in it, according to their kinds, and every winged bird according to its kind. And God saw that it was good. 22 God blessed them and said, “Be fruitful and increase in number and fill the water in the seas, and let the birds increase on the earth.” 23 And there was evening, and there was morning—the fifth day.
 24 And God said, “Let the land produce living creatures according to their kinds: the livestock, the creatures that move along the ground, and the wild animals, each according to its kind.” And it was so. 25 God made the wild animals according to their kinds, the livestock according to their kinds, and all the creatures that move along the ground according to their kinds. And God saw that it was good.
    26 Then God said, “Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals,[a] and over all the creatures that move along the ground.”
 27 So God created mankind in his own image,
   in the image of God he created them;
   male and female he created them.
 28 God blessed them and said to them, “Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground.”
    29 Then God said, “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food. 30 And to all the beasts of the earth and all the birds in the sky and all the creatures that move along the ground—everything that has the breath of life in it—I give every green plant for food.” And it was so.
    31 God saw all that he had made, and it was very good. And there was evening, and there was morning—the sixth day.

Michael Shermer's Genenis:  Revisited
"To convey the logical absurdity of trying to squeeze the round peg of science into the square hole of religion, I penned the following scientific revision of the Genesis creation story. It is not intended as a sacrilege of the poetic beauty of Genesis; rather, it is a mere extension of what the creationists have already done to Genesis in their insistence that it be read not as mythic saga but as scientific prose. If Genesis were written in the language of modern science, it would read something like this."




The transcript...

In the beginning — specifically on October 23, 4004 B.C., at noon — out of quantum foam fluctuation God created the Big Bang. The bang was followed by cosmological inflation. God saw that the Big Bang was very big, too big for creatures that could worship him, so He created the earth. And darkness was upon the face of the deep, so He commanded hydrogen atoms (which He created out of Quarks and other subatomic goodies) to fuse and become helium atoms and in the process release energy in the form of light. And the light maker he called the sun, and the process He called fusion. And He saw the light was good because now He could see what he was doing. And the evening and the morning were the first day.

And God said, Let there be lots of fusion light makers in the sky. Some of these fusion makers appear to be more than 4,004 light years from Earth. In fact, some of the fusion makers He grouped into collections He called galaxies, and these appeared to be millions and even billions of light years from Earth, so He created “tired light” — light that slows down through space — so that the 4004 B.C. creation myth might be preserved. And created He many wondrous splendors, including Red Giants, White Dwarfs, Quasars, Pulsars, Nova and Supernova, Worm Holes, and even Black Holes out of which nothing can escape. But since God cannot be constrained by nothing (can God make a planet so big that he could not lift it?), He created Hawking radiation through which information can escape from Black Holes. This made God even more tired than tired light, and the evening and the morning were the second day.

And God said, Let the waters under the heavens be gathered together unto one place, and let the continents drift apart by plate tectonics. He decreed sea floor spreading would create zones of emergence, and He caused subduction zones to build mountains and cause earthquakes. In weak points in the crust God created volcanic islands, where the next day He would place organisms that were similar to but different from their relatives on the continents, so that still later created creatures called humans would mistake them for evolved descendants. And in the land God placed fossil fuels, natural gas, and other natural resources for humans to exploit, but not until after Day Six. And the evening and the morning were the third day.

And God saw that the land was lonely, so He created animals bearing their own kind, declaring Thou shalt not evolve into new species, and thy equilibrium shall not be punctuated. And God placed into the land’s strata, fossils that appeared older than 4004 B.C. And the sequence resembled descent with modification. And the evening and morning were the fourth day.

And God said, Let the waters bring forth abundantly the moving creatures that hath life, the fishes. And God created great whales whose skeletal structure and physiology were homologous with the land mammals he would create later that day. Since this caused confusion in the valley of the shadow of doubt God brought forth abundantly all creatures, great and small, declaring that microevolution was permitted, but not macroevolution. And God said, “Natura non facit saltum” — Nature shall not make leaps. And the evening and morning were the fifth day.

And God created the pongidids and hominids with 98 percent genetic similarity, naming two of them Adam and Eve, who were anatomically fully modern humans. In the book in which God explained how He did all this, in chapter one He said he created Adam and Eve together out of the dust at the same time, but in chapter two He said He created Adam first, then later created Eve out of one of Adam’s ribs. This caused further confusion in the valley of the shadow of doubt, so God created Bible scholars and theologians to argue the point. 

And in the ground placed He in abundance teeth, jaws, skulls, and pelvises of transitional fossils from pre-Adamite creatures. One he chose as his special creation He named Lucy. And God realized this was confusing, so he created paleoanthropologists to sort it out. And just as He was finishing up the loose ends of the creation God realized that Adam’s immediate descendants who lived as farmers and herders would not understand inflationary cosmology, global general relativity, quantum mechanics, astrophysics, biochemistry, paleontology, population genetics, and evolutionary theory, so He created creation myths. But there were so many creation stories throughout the land that God realized this too was confusing, so he created anthropologists, folklorists, and mythologists to settle the issue. 

By now the valley of the shadow of doubt was overrunneth with skepticism, so God became angry, so angry that God lost His temper and cursed the first humans, telling them to go forth and multiply (but not in those words). They took God literally and 6,000 years later there are six billion humans. And the evening and morning were the sixth day.

By now God was tired, so God said, “Thank me its Friday,” and He made the weekend. It was a good idea.

In Conclusion...

What do you think?  Should the story of Genesis be taken literally?  If not, does it have room for science, or are they mutually exclusive?

10 Myths and Misconceptions About Evolution

Evolution VS Creationism:  How many times have you heard those words bundled together? 

Although there is no real debate in the scientific community with respect to evolution, creationists and “IDers” (those who believe in Intelligent Design, a fancy name for “creationism”) attempt to stir the pot in the quest to find the origin of life.

The Skeptic’s Society has once again created a wonderful ePamphlet that is available for download on their site.  It tackles the myths and misconceptions surrounding evolution, and is titled:  “Top 10 Myths About Evolution (And How We Know It Really Happened)”.

The myths include:

1)  If humans evolved from apes, why are apes still around?  (incidentally, this topic has been reviewed in a previous article on Relatively Interesting, called “If Humans Evolved From Apes, 
Why Do Apes Still Exist?”)


Humans, apes, and monkeys are only distant evolutionary “cousins.” We come not from apes but from a common ancestor that was neither ape nor human that lived millions of years in the past. In fact, during the last seven million years many human-like species have evolved; some examples include Homo habilis, Homo erectus, and Homo neanderthalensis. All of these went extinct at different times, leaving just us to share the planet with a handful of other primates.


2)  There are too many gaps in the fossil record for evolution to be true.


In fact, there are lots of intermediate fossils. Archaeopteryx, for example, is one of the earliest known fossil birds with a reptilian skeleton and feathers. There is now evidence that some dinosaurs had hair and feathers. Therapsids are the intermediates between reptiles and mammals, Tiktaalik is an extinct lobe-finned fish intermediate to amphibians, there are now at least six intermediate fossil stages in the evolution of whales, and in human evolution there are at least a dozen intermediate fossil stages since hominids branched off from the great apes six million years ago. Considering the exceptionally low probability that a dead plant or animal will fossilize it is remarkable we have as many fossils as we do. First the dead animal has to escape the jaws of scavengers. Then is has to be buried under the rare circumstances that will cause it to fossilize instead of decay. Then geological forces have to somehow bring the fossil back to the surface to be discovered millions of years later by the handful of paleontologists looking for them.

3)  If evolution happened over millions of years, why doesn’t the fossil record show gradual change?

Sudden changes in the fossil record are not missing evidence of gradualism; they are extant evidence of punctuation. Species are stable over long periods of time and so they leave plenty of fossils in the strata while in their stable state. The change from one species to another, however, happens relatively quickly (on a geological time scale) in a process called punctuated equilibrium. One species can give rise to a new species when a small “founder” group breaks away and becomes isolated from the ancestral group. This new founder group, as long as it remains small and detached, may experience relatively rapid change (large populations are genetically stable). The speciational change happens so rapidly that few fossils are left to record it. But once changed into a new species, the individuals will retain their phenotype for a long time, leaving behind many well-preserved fossils. Millions of years later this process results in a fossil record that records mostly stability. The punctuation is there in between the equilibrium.

4)  No one has ever seen evolution happen.

Evolution is a historical science confirmed by the fact that so many independent lines of evidence converge to this single conclusion. Independent sets of data from geology, paleontology, botany, zoology, biogeography, comparative anatomy and physiology, genetics, molecular biology, developmental biology, embryology, population genetics, genome sequencing, and many other sciences each point to the conclusion that life evolved. Creationists demand “just one fossil transitional form” that shows evolution. But evolution is not proved through a single fossil. It is proved through a convergence of fossils, along with a convergence of genetic comparisons between species, and a convergence of anatomical and physiological comparisons between species, and many other lines of inquiry. (In fact we can see evolution happen—especially among organisms with short reproductive cycles that are subject to extreme environmental pressures. Knowledge of the evolution of viruses and bacteria is vital to medical science.)

5)  Science claims that evolution happens by random chance. 

Natural selection is not “random” nor does it operate by “chance.” Natural selection preserves the gains and eradicates the mistakes. To illustrate this, imagine a monkey at a
typewriter. In order for the monkey to type the first 13 letters of Hamlet’s soliloquy by chance, it would take 2613 number of trials for success. This is 16 times as great as the total number of seconds that have elapsed in the lifetime of the solar system. But if each correct letter is preserved and each incorrect letter eradicated, the phrase “tobeornottobe” can be “selected for” in only 335 trials, or just seconds in a computer program. Richard Dawkins defines evolution as “random mutation plus nonrandom cumulative selection.” It is the cumulative selection that drives evolution. The eye evolved from a single, light sensitive spot in a cell into the complex eye of today not by chance, but
through thousands of intermediate steps, each preserved because they made a better eye. Many of these steps still exist in nature in simpler organisms.

6)  Only an intelligent designer could have made something as complex as the eye.

The anatomy of the human eye shows that it is anything but “intelligently designed.” It is built upside down and backwards, with photons of light having to travel through the cornea, lens, aqueous fluid, blood vessels, ganglion cells, amacrine cells, horizontal cells, and bipolar cells, before reaching the light sensitive rods and cones that convert
the light signal into neural impulses, which are then sent to the visual cortex at the back of the brain for processing into meaningful patterns. For optimal vision, why would an intelligent designer have built an eye upside down?

7)  Evolution is "only a theory".

All branches of science are based on theories, which are grounded in testable hypothesis and explain a large and diverse body of facts about the world. A theory is considered robust if it consistently predicts new phenomena that are subsequently observed. Facts are the world’s data. Theories are explanatory ideas about those data. Constructs and other nontestable statements are not a part of science. The theory of evolution meets all the criteria of good science, as determined by Judge William Overton in the Arkansas creationism trial:


• It is guided by natural law.
• It has to be explanatory by reference to natural law.
• It is testable against the empirical world.
• Its conclusions are tentative.
• It is testable and falsifiable.


If you can find fossil mammals in the same geological strata as trilobites then evolution would be falsified. No one has ever found such contradictory data.

8)  Evidence for human evolution has turned out to be fake, frauds, or fanciful.

Eager to discredit evolution, creationists ignore hominid fossil discoveries and cherry pick examples of hoaxes and mistakes in the belief that mistakes in science are a sign of weakness. This is a gross misunderstanding of the nature of science, which constantly advances by using both its mistakes and the successes. Its ability to build cumulatively on the past is how science progresses. The self-correcting feature of the scientific method is one of its most powerful assets. Hoaxes like Piltdown Man, and honest mistakes like Nebraska Man, Calaveras Man, and Hespero-pithecus, are, in time, corrected. In fact, it wasn’t creationists who exposed these errors, it was scientists who did so. Creationists simply read about the scientific exposé of these errors, and then duplicitously claimed them as their own. Piltdown Man and backwards? This “design” only makes sense if natural
selection built eyes from available materials, and in the particular configuration of the ancestral organism’s pre-existing organic structures. The eye shows the pathways of evolutionary history, not intelligent design.

9)  The second law of thermodynamics proves that evolution is impossible.

The Second Law of Thermodynamics applies to closed, isolated systems. Since the Earth receives a constant input of energy from the sun—it is an open-dissipative system—entropy may decrease and order increase (though the sun itself is running down in the process). Thus, the Earth is not strictly a closed system and life may evolve without violating natural law. As long as the sun is burning, life may continue thriving and evolving, just like automobiles may be prevented from rusting, burgers can be heated in ovens, and all manner of things in apparent violation of Second Law entropy may continue. But as soon as the sun burns out, entropy will take its course and life on Earth will cease.

10)  Evolution can’t account for morality.

As a social primate species we evolved a deep sense of right and wrong in order to accentuate and reward reciprocity and cooperation, and to attenuate and punish excessive selfishness and free riding. As well, evolution created the moral emotions that tell us that lying, adultery, and stealing are wrong because they destroy trust in human relationships that depend on truth-telling, fidelity, and respect for property. It would not be possible for a social primate species to survive without some moral sense. On the constitution of human nature is built the constitutions of human societies.

Bonus myth (not in the pdf):
  “Believing” in evolution is no different than believing in any faith based religion.

I think this is more of an error in semantics when using the word “belief or believe”.  For example, I don’t “believe” in evolution.  I accept evolution because there is a convergence of evidence in the scientific community that indicates that evolution is a completely viable theory to explain the diversity of life.

I find it interesting to observe the debate between evolutionists and creationists.  The myths listed above invariably come up in many discussions, and the creationist will cling to some obscure anomaly, thinking that this one “missing piece” can bring down the entire theory.  Since one fact does not prove a theory, one anomaly does not disprove it either.  Again, it’s the convergence of data that makes a theory sound.

In any case, I highly recommend the aforementioned download, as it can be used as a plain-English, simple way to defend evolution against its myths and misconceptions.

The Cambodian Stegosaurus: Proof That Humans And Dinosaurs Coexisted?

Deep within the Cambodian jungle lie the magnificent ruins left by the Khmer empire, including the temple of Angkhor.  The structures were built in the beginning of the eighth century AD until the fourteenth century AD.  The artistic skills of the Khmer are evident throughout the complex: most notably, their reliefs, carved into the stone surface of the walls and buildings.


One particular relief displays a number of animals:  what appears to be a monkey, a deer, buffalo, parrots, various swans, a gecko lizard, and... a stegosaurus!  


Hold the phone:  if an artist was able to carve a stegosaurus, the he
must have seen one with his own eyes, and therefore, this is amazing evidence that humans and dinosaurs actually coexisted!  

Or so the folks over at
Bible.ca claim.

The reliefs of the other animals are not necessarily easy to identify.  The "swans" could be any related species.  In fact, had the author not pointed out that it was a swan or water buffalo, I wouldn't be able to identify either.  In fact, I would only go so far as to say "a bird with a long neck that looks like a swan".  The dinosaur in question, at first glance, looks like a stegosaurus.  Or does it?


From the author:

"A few skeptics have based their objections on anatomical differences between popular Stegosaurus restorations and the Cambodian sculpture. The fact that the average Jr. High student immediately identifies the sculpture as a Stegosaurus is considered of no consequence. "The head is too large Stegosaurs had no horns or frills on the head" The sculpture has no spikes on the tail... Therefore, they conclude that the sculptor never saw a Stegosaurus."
It may be true that a 13 year old who sees the carving would jump to the conclusion that it is a stegosaurus, likely because of the "plates" on the spine of the creature and because stegosaurus is one of the most recognizable dinosaurs, along with T-Rex, Apatosaurus, Velociraptor, and Triceratops.  But that doesn't mean it's true that the artist saw a stegosaurus. And it certainly doesn't prove that the creature is a stegosaurus either.   It just proves that it looks like a stegosaurus.

The creature in the relief, except for the "plates" (which we can't even prove are plates - they could be decoration behind the animal, since many of the other animals have similar decorations) doesn't really looks like a stegosaurus.  The head is too large; the spikes on the tail are missing; the carving shows two giant horns or frills above the eyes; and the front legs are the same size as the back legs (the front legs of a stegosaurus are much shorter).

As many other bloggers on the Web point out, the carving looks like a chameleon, which are incredibly fascinating reptiles.  One could see how a color-changing creature could earn its way onto a temple wall.  If you spend enough time on searching, you can find a better match than the one in the image to the right.


Or it could be another lizard altogether.  'Acanthosaura' is a genus of lizards commonly known as 'mountain horned dragons', or 'pricklenape agamas'. They are so named because of a row of dorsal spines which run down the back of their neck. They are arboreal lizards that are found in Southeast Asia.

At least three species are native to Cambodia, so there is a decent chance that the artist would have been exposed to them.  ''Acanthosaura capra'' resides in Cambodia, Laos, and Vietnam. ''Acanthosaura crucigera'', resides in Myanmar, Thailand, C Vietnam, Malaysia, and Cambodia. ''Acanthosaura lepidogaster'' are also native to Thailand, Vietnam, Cambodia, Myanmar, and China.

A quick invocation of Occam's Razor once again provides us with a simple solution:  it's not a stegosaurus, it's some other native animal to Cambodia.

Stegosaurus lived between 150 and 145 million years ago, in the Late Jurassic period.  The fossil record does not yield any more stegosaurs after their extinction. It is an extraordinary leap to assume that
one carving of a barely identifiable creature is a stegosaurus, and an even bigger leap to then suggest that dinosaurs coexisted with humans, thus "proving" Creationism and a young Earth.


As a child, I wanted to be a paleontologist.  Jurassic Park was the best book ever, and the movies were fantastic.  I would be thrilled if the carving was that of a stegosaurus.  But, unfortunately, one anomaly does not disprove a massive convergence of evidence to suggest that dinosaurs (all dinosaurs) went extinct about 65 million years ago and never, ever, coexisted with humans.
Even the folks over at the GeoChristian blog don't buy into the story:
"In conclusion, to use the Ta Prohm carving as evidence that humans and dinosaurs lived together only a short time ago is bad apologetics. This is one more thing to make us look silly in the eyes of nonbelievers. Don’t feed this to your kids, and don’t use it to try to convince anyone of the truthfulness of Scriptures."
And besides, if you're still on the fence:  the carving could be a fake, created in recent history.

The temple has been used in the Lara Croft Tombraider movies, after all.
