Here are the books I’ve been working on in August:
- Beyond Creation Science — by Timothy Martin and Jeffery Vaughn. A good Biblical analysis of young-Earth creationism mixed with a “Jesus has already returned” eschatology (full preterism).
- The History of the Ancient World — by Susan Wise Bauer. I’ve been in this book all summer, and am up to the Assyrian conquest of Egypt.
- Dune — science fiction novel by Frank Herbert. The book is interesting for its perspectives on ecology as well as its plot and imagination. “You cannot go on forever stealing what you need without regard to those who come after.” (Kynes having a delusion of his father lecturing him as Kynes is dying in the desert)
- The Apocrypha — Though not considered to be Scripture by Protestants, these Jewish writings fill in the historical gap between Old and New Testaments. These books were included in Luther’s German Bible and in the 1611 King James Version. This month, I read the additions to the Biblical book of Daniel, which are valuable stories even if they are not part of Scripture:
- The Song of the Three — Contains the supposed prayer of Abednego in the furnace, as well as a psalm of praise sung by the three when they were delivered.
- Susanna — Daniel’s wisdom rescues a “very beautiful and devout woman” named Susanna from her lustful, false accusers. This story is chapter 13 of Daniel in Catholic and Orthodox Bibles.
- Bel and the Dragon — Daniel shows the king that it is the priests of the Babylonian god Bel, not Bel himself, who dine on offerings placed before Bel’s idol. This story is added as chapter 14 of Daniel.

P.S. There is an edition of The English Standard Version (ESV) with Apocrypha. In this edition, the Apocrypha is after Revelation, rather than between the two Testaments where it is usually inserted. I have never seen a New International Version (NIV) Bible with the Apocrypha. I’ve been reading the New English Bible with Apocrypha, which I picked up at a book fair for really cheap.
There is nothing new on the job search. I am seeking employment as either a geoscience or geospatial professional (or both combined in one position).
As I told one of my daughters a few months ago: “I’ve found plenty of jobs; they just haven’t found me.”
I’m just about done with my final post in my “Six bad arguments from Answers in Genesis” series. My next series is going to be “The three pillars of young-Earth creationism,” where I’ll take a look at problems with the three basic YEC Biblical arguments for the Earth being only 6000 years old:
- Genesis 1 requires six, consecutive, literal 24-hour days.
- Genesis 3 requires no animal death before the fall.
- Genesis 6-9 requires a global flood that produced the Earth’s sedimentary rock record.
I hope to demonstrate that each of these pillars rests on a questionable foundation based on what the Bible actually says, rather than what the young-Earthers read into it. The science against young-Earth creationism is a slam-dunk, but I’ll stick mostly (or entirely) to Biblical arguments for this series.

From today’s Astronomy Picture of the Day: Morning Glory Clouds Over Australia.
The text description from APOD:
Explanation: What causes these long, strange clouds? No one is sure. A rare type of cloud known as a Morning Glory cloud can stretch 1,000 kilometers long and occur at altitudes up to two kilometers high. Although similar roll clouds have been seen at specific places across the world, the ones over Burketown, Queensland Australia occur predictably every spring. Long, horizontal, circulating tubes of air might form when flowing, moist, cooling air encounters an inversion layer, an atmospheric layer where air temperature atypically increases with height. These tubes and surrounding air could cause dangerous turbulence for airplanes when clear. Morning Glory clouds can reportedly achieve an airspeed of 60 kilometers per hour over a surface with little discernible wind. Pictured above, photographer Mick Petroff photographed some Morning Glory clouds from his airplane near the Gulf of Carpentaria, Australia.

I saw The Reason for God by Timothy Keller at Costco for only $8.99. Or you can get it for $10.88 on Amazon. You decide.
As I have said before, I recommend this book for
- Skeptics — If you reject Christianity because what you have read from the New Atheists, you owe it to yourself to read this book.
- Doubters — If you are struggling in your faith because of intellectual doubts, this might be the book for you.
- Mature Christians — If you want to be more effective in your discussions with skeptics and doubters, this book can add some apologetics tools to your toolbox.

Here are some results of a PEW Research Center study on the religious and political beliefs of scientists:
|42% — Scientists ages 18-34 who say they believe in God.|
|28% — Scientists 65 and older who say this.|
What does this mean? Does it mean that an increasing number of scientists believe in God? Or does it mean that young scientists give up their faith as they grow older? Unfortunately, this study is just a snapshot in time. It would be helpful to see the results of similar surveys done over time, or the results of studies that follow the same scientists throughout their careers.
|3% — Percentage of scientists who are “white evangelicals”.|
|19% — Percentage of Americans who are “white evangelicals”.|
What does this mean? Either we evangelicals are doing a pitiful job of preparing and motivating our young people to enter the sciences, or they fall away from faith once they do enter the sciences. I place part of the blame for both of these possibilities on the dominance of young-Earth creationism in our Christian educational system, whether in our private schools, home schools, or churches. Students are either scared away from the sciences because of the perceived warfare between science and faith, or they are ill-equipped to see God’s world as it is, especially in terms of Earth history. There are likely to be a number of other factors as well.
|Field||Believe in God
||Believe in higher power
||Believe in neither
|Biology and medicine||32||19||41|
|Physics and astronomy||29||14||46|
There is not as much of a difference between the different fields of science as I had been led to believe by some other studies. I had thought that astronomers were more likely to believe in God or some sort of a higher power than other scientists, but according to this study this isn’t the case.
In the geosciences, 47% of scientists are in the “believe in neither” category: atheists and agnostics. But at 30%, we theists are not all that far behind, and I find this encouraging.
One more item from the study that I found interesting, though it related to politics rather than religious beliefs:
|Statistic #4 — Party affiliation among scientists
- Is there a trend towards increasing faith among scientists, as indicated by statistic #1, or will these young scientists lose faith as they grow older?
- Why are only 3% of scientists evangelical Christians? What can we evangelicals do about it?
- Is there any significance to the differences between the various fields of science? Are chemists most likely to believe in God because their science doesn’t have as direct of a relationship to the issue of origins?
- Why do only 6% of scientists identify themselves as Republican? What can be done about it?

I’m still plugging away on the job search. I know that I am competing against 50 to 100 people (or more) for many of the positions I have applied for. My lovely wife tells me that I should feel pretty good about being a finalist for a number of these positions. Yes, but I’d sure rather be employed than just feeling good about myself at this point.
I still have a tentative offer for an excellent position, but it may not start until 2010, and I can’t wait that long (and they know that). If I can find good temporary work, this might still work out. Until it is a done deal, however, I’m still looking for a permanent position.
What does one do in a long period of unemployment, other than networking and working on applications?
- I’ve been taking GIS classes from ESRI to expand and update my skills. The course I’m working on now is “Creating and Integrating Data for Natural Resource Applications.” I also took a course on the geochemistry of gas shales this summer.
- Long walks in the mountains and foothills. I saw my first western tanager last week—a very pretty bird.
- Lunch dates with my wife.
- Reading books.
- Going to the apartment complex swimming pool with the family.
- We’re going to a Colorado Rockies baseball game this week. My wife found some seats for $1 each!
- Writing blog posts on The GeoChristian helps to keep me sane.
The greatest number of comments in the past week have been on my “Seeing God in nature” post. What is the difference between ID and the theistic evolution of Francis Collins? Is God a malevolent bioterrorist?

|This is part five of a six-part series examining supposed evidences for a global flood that have recently appeared on the Answers in Genesis web site.|
|The people at AiG are my brothers and sisters in Christ, and I share their love for the Lord Jesus Christ, their respect for the Bible as the Word of God, and their desire to see people come to faith in Christ. However, I view their arguments for a young Earth and geological catastrophism as unnecessary Biblically, as poor apologetics, and as a serious obstacle to the evangelism of scientists.|
|Unfortunately, few people in our churches or Christian education system have the geological background to critically analyze these arguments. The result is that people read articles like these from AiG, find them to be rather impressive, and believe that these present sound arguments in defense of the Bible. The opposite, however, is true. A vast majority of Christian geologists find the arguments for a young Earth and the geologic work of the Flood to be untenable. It is my strong opinion that the young-Earth arguments of young-Earth creationist organizations like AiG have no place in our churches and Christian education system.|
|Part one examined the young-Earth creationist (YEC) argument that fossils at high elevations are proof of a global flood.|
|Part two examined the YEC argument that sedimentary rocks that contain dense accumulations of fossils can best be described by the action of Noah’s Flood.
|Part three examined the YEC perception that transcontinental rock layers, such as the sandstone layer that is found at the base of the Paleozoic sediments throughout much of North America, can best be explained by Noah’s flood.|
|Part four looked at the YEC claim that long-distance transport of sand grains can only be explained by Noah’s flood.
“Flood evidence number five” from Answers in Genesis is called “No Slow and Gradual Erosion.” Young Earth geologist Dr. Andrew Snelling begins this article with a major overstatement:
“Today we see the effects of weathering and erosion all around us. But where is the evidence of millions of years between rock layers? There is none.”
To say that there is no evidence for extensive weathering and erosion in the geologic column is simply not true.
The geologic record is comprised not only of rocks formed by deposition of sediments, but also by the gaps between these rock layers which represent times of non-deposition or erosion. In order to make his case that there is no evidence for long periods of weathering and erosion in the geologic record, Snelling looks at four examples of contacts between formations in the Grand Canyon, while ignoring perhaps the greatest example of weathering in the canyon’s sedimentary rock layers. In each of these cases, the standard geological interpretation is that there was a period of time—in some cases over 100 million years—between the deposition of these formations. Snelling attempts to show that deposition of these units occurred during Noah’s flood, with only minimal time gaps between the formations.
Snelling uses the following examples:
1. The contact between the Cambrian Tapeats Sandstone and the underlying Precambrian rocks.
The Precambrian rocks at the base of the Grand Canyon include layered sedimentary rocks (see picture below) as well as metamorphic rocks. These were eroded to a flat surface before the Tapeats Sandstone was deposited (the Tapeats was discussed back in part 3 of this series).
According to Snelling, there is no evidence for weathering (e.g. soil formation) on the Precambrian surface.
- It may be true that no paleosols (ancient soil layers) have been found beneath the Tapeats in the Grand Canyon, but certainly the deposition, lithification (process of turning sediment into stone), and tilting of the Precambrian sedimentary rocks and their subsequent beveling off took some time and involved erosional processes. Some young-Earth creationists would claim that these Precambrian rocks are pre-Flood deposits, but it should be noted that they contain some fossils, such as stromatolites and even possible jellyfish.
- If the Flood had eroded the Precambrian (pre-Flood rocks in the young-Earth scenario), we should expect to see a very uneven surface. The basement rocks (Vishnu Schist and associated granitic rocks) would be very resistant to erosion and should have formed topographic highs. The Precambrian sedimentary rocks would have had varying levels of resistance to erosion, and should have formed a series of ridges and valleys, with the more-resistant layers forming the ridges. It is difficult to visualize a global flood creating a flat surface like what is observed.
- There is a modern analog for a flat surface on Precambrian rocks. The Canadian Shield is a vast region covering much of eastern Canada as well as portions of northern Minnesota and Wisconsin. It is composed of hard metamorphic and igneous rocks, which once formed the roots of mountain ranges. The Canadian Shield illustrates that erosional processes can reduce even the most resistant rocks to a level surface. (The Canadian shield is not perfectly flat, of course, though relief in most of the region is low. It was likely considerably more planar before being scraped by glaciers repeatedly during the Pleistocene Ice Ages.)
- There may not be paleosols (soil horizons) developed on the Precambrian rocks in the Grand Canyon, but they are present elsewhere, such as the contact between Precambrian basement rocks and the Cambrian Lamotte Formation in Missouri.
2. The contact between the Mississippian Redwall Limestone and the underlying Devonian Temple Butte Formation and Cambrian Muav Limestone.
Snelling correctly observes that the top of the Muav contains what appear to be erosional channels, some of which are filled with the material that makes up the Temple Butte Formation. However, Snelling dismisses these as evidence for stream erosion, preferring to interpret these channels as having been caused by the Flood.
Snelling goes further to claim that the Redwall and Muav show signs of interbedding. The contacts between some rock units are distinct. For example, higher in the geologic column, there is a distinct point where the Hermit Shale ends and the Coconino Sandstone begins (see #4 below). There is no mixing of any sort between the two.
Not all contacts between formations are this sharp; some are considerably more transitional. Interbedding is a type of transition where there are alternating beds of the upper and lower formations, so rather than going directly from formation A to formation B, the transition might go A-B-A-B-A-B.
The two preceeding diagrams represent what one might see in an individual outcrop. Over greater distances—tens or even hundreds of kilometers—the situation might look more like this:
This could represent a migrating shoreline as the sediments pile up, with unit A being deposited further to the right at some times, and further to the left at others. An important part of this concept is that A and B are being deposited at the same time, one closer to the shoreline, and one further out.
If the Muav and Redwall were truly interbedded, it would be a major challenge to accepted interpretations. The Muav is Cambrian, and the Redwall is Mississippian, so there should be over 100 million years of non-deposition or erosion represented by the boundary between the two. If they are interbedded, this would imply that they were being deposited at the same time.
- The channels beneath the Redwall appear to be real stream channels, though as far as I know this cannot be conclusively demonstrated at this time.
- The Temple Butte Limestone fills these channels. Paleontological evidence suggests that this is a freshwater limestone. How did this happen during a global salt-water flood?
- A diagram of the supposed interbedding is shown here (figure 3). The blotchy nature of the contact between what the authors call the Muav and what they call the Redwall looks like a secondary, post-depositional feature (diagenetic) rather than a primary, depositional feature. This could have been formed by groundwater at any time after the deposition of the Redwall Limestone. If this were true interbedding, it certainly would have been puzzled over by many a geologist hiking along the very popular North Kaibab Trail in the Grand Canyon.
3. The contact between the Permian Hermit Shale and the underlying Pennsylvanian Esplanade Sandstone.
Snelling claims that interbedding of the Hermit and Esplanade proves that there was not millions of years between their deposition.
- This may be a case where interbedding is legitimate; they could represent adjoining sedimentary environments, at least for a time. There is not a huge time gap between the two formations.
- The erosional relief on top of the Esplanade is up to 16 m (60 ft), which appears to be the result of stream erosion. (USGS Geologic Investigations Series I–2688). Snelling doesn’t mention this.
- Paleontological and petrologic (rock) evidence indicates that both of these units were formed in swampy environments, not in a global flood.
4. The contact between the Coconino Sandstone and the underlying Hermit Shale, both of Permian age.
In the previous two examples, Snelling says the boundaries between formations appeared to be too diffuse to represent vast gaps in geologic history. The Coconino-Hermit boundary, on the other hand, appears to Snelling to be too sharp.
- The Coconino is a wind-deposited sandstone, with terrestrial arthropod and reptile tracks, as well as animal burrows. What were paleo-lizards doing running around on the sand in the middle of the flood? By itself, this ought to rule out a flood explanation for the Coconino.
- In an increasingly arid environment, it should not be surprising that there is little in the way of stream channel erosion or soil development beneath the Coconino.
Snelling completely ignores two compelling pieces of evidence for long periods of weathering and erosion in geologic history:
1. Paleosols — I have briefly referred to paleosols (ancient soils) already. The formation of a soil on top of bare rock or sediment takes a combination of physical weathering, chemical weathering, biological processes, and time, and is a process that normally takes thousands of years. If paleosols exist within the geologic record, they are strong evidence that there were long periods of time when rocks or sediments were exposed on the surface to the atmosphere.
My graduate research was in the Palouse Loess of Eastern Washington, which contains multiple, stacked paleosols. Each of these paleosols contains soil horizons identical in character to modern soil profiles in the area, complete with root casts and animal burrows. Each paleosol would have taken several hundred or even thousands of years of surface stability to form, only to be buried by an influx of wind-blown silt, setting the stage for the next time of soil formation. The Palouse Loess is a Quaternary formation, and young-Earth creationists would say that this was formed after the Flood.
I did a quick search in the Geological Society of America Bulletin, and came up with the following articles describing paleosols in Paleozoic and Mesozoic rocks:
- δ13C depth profiles from paleosols across the Permian-Triassic boundary: Evidence for methane release
- Greenhouse crises of the past 300 million years
- Paleokarst, paleosol, and rocky-shore deposits at the Mississippian-Pennsylvanian unconformity, northwestern Arkansas
- High latitude meteoric δ18O compositions: Paleosol siderite in the Middle Cretaceous Nanushuk Formation, North Slope, Alaska
- Paleoclimatic inferences from paleopedology and magnetism of the Permian Maroon Formation loessite, Colorado, USA
This is from just one journal; there are undoubtedly thousands of documented paleosols in the geologic record. A majority of the articles I found were about Cenozoic paleosols, but I ignored these for brevity and also because many young-Earth creationists describe Cenozoic rocks as being post-Flood (a position which has just about as many problems as the rest of young-Earth creationism).
2. Paleokarst — Karst topography is formed by the dissolution of carbonate rocks, such as limestone. Features of karst topography include caves, sinkholes, and disappearing streams.
Karst topography is common in areas underlain by limestone, and one would expect that this would have been the case throughout geologic history. Snelling completely ignores the greatest evidence for weathering and erosion in the Grand Canyon, and this is the paleokarst (ancient karst) that exists in the Redwall Limestone. Snelling wrote about the bottom of the Redwall, but not its top! The Redwall appears to have all the features of karst topography, such as rubble (breccia) filling sinkholes, and a chaotic upper surface.
Karst topography on top of the Redwall implies that there was a considerable amount of time when the consolidated limestone—as opposed to fresh limey sediments—was exposed to the atmosphere, with freshwater circulating through the rocks. This could not have happened in the context of a global flood.
Additional problems for the flood-geology/young-Earth position:
Many of the features I have described are difficult to explain within the young-Earth model for Earth history. These include ancient soil layers, ancient karst systems, and the difficulty of producing the flat surface that underlies the Cambrian in the Grand Canyon.
Young-Earth creationists seem to acknowledge that the geologic record contains evidence of periods of non-deposition and erosion, as well as periods of deposition. The difference would be a matter of time scales. Geologists are willing to talk about periods of millions of years, whereas young-Earth creationists have to squeeze these events into periods of hours or days.
What sort of erosion would occur in a global flood? The young-Earth literature implies that the flood began with an intense period of erosion, with forces powerful enough to pulverize granite. It seems that this continued in various places throughout the flood. Would we not expect, therefore, that a significant feature of the geologic record would be mega-scouring of soft sediments? Snelling refers to something called “sheet erosion” which conveniently doesn’t scour soft sediments. I don’t think he can have it both ways: sufficiently strong to shatter granite, but gentle enough to produce smooth surfaces on mud and sand.
There are numerous other indicators of a passage of time within the rock record. These include vertebrate (amphibian, reptile) nests, which imply a time when the land was sufficiently dry for a long enough time to allow mating, nest-building, and rearing of young (at least some dinosaurs cared for their young). This could not have happened in the middle of the Flood. Other shorter-term indicators of periods of non-deposition include worm burrows, raindrop impressions, and mudcracks, all of which are common.
There is considerable evidence in the geologic record for long periods of slow, gradual weathering and erosion. Paleosols represent periods of stability, when sediments or rocks were exposed to the atmosphere for long periods of time. These ancient soils include features such as plant roots and animal burrows. The contacts between sedimentary formations represent periods of erosion or non-deposition, and often are somewhat irregular, being cut by stream channels. In other places, limestone formations show signs of having been exposed to freshwater groundwater circulation, resulting in paleokarst.
As with the other “flood evidences,” this one turns out to be completely inadequate as an explanation for how the Earth got to be the way it is. Because of this, Flood Evidence #5 ought not to be used in defense of the truthfulness of God’s holy word, the Bible.
With love for the body of Christ.
According to the Bible (for example Romans 1; Psalm 19), nature should point us to God. Author Philip Yancey writes about this in Christianity Today: A Whole Good World Outside: Opening our blinds to the prevailing wonder of creation. Here’s a quote:
It was this whole good world outside as much as anything that brought me back to Christian faith. I emerged from childhood with a distorted image of God: a frowning Supercop looking to squash anyone who might be having a good time. I have since come to know God as a whimsical artist who fills the world with creatures like the porcupine and skunk and warthog, who lavishes the world with wildflowers and tropical fish more beautiful than any design on display in an art museum.
Francis Collins, former director of the Human Genome Project, sees God’s hand in the magnificent coding of the DNA double helix. Pulitzer Prize-winning author Annie Dillard sees it in the creatures that swim and dive in Tinker Creek in the Blue Ridge Mountains of Virginia. From nature writers such as John Muir, Henri Fabre, Loren Eiseley, and Lewis Thomas I gain appreciation for a Master Artist they may not even believe in; their precise and reverent observations help to raise the blinds for me.
I have met a pastor in Bahrain who can identify by sight 2,000 species of seashells, and a missionary in Costa Rica who has assembled a world-class collection of butterflies and moths. Church historian Mark Noll remarks that the song “Turn Your Eyes upon Jesus” plainly errs when it says, “And the things of earth will grow strangely dim in the light of his glory and grace.” No, he says, the rest of the world grows clearer, not dimmer, in the light of Christ. God created matter; in Jesus, God joined it.

I didn’t get as much reading done in July as I would have liked, but here’s the one book I did finish:
- The Reason for God, by Timothy Keller. The chapters address:
- The idea that there cannot be only one true religion
- The problem of evil — how can a good God allow suffering?
- The proposition that Christianity makes one narrow and restricts one’s freedom
- The accusation that Christianity is the source of many injustices
- Science and Christianity (I have a quote from the author here)
- The historical reliability of the Bible
- The clues of God
- Moral obligation
- Sin and its consequences
- The cross
- The resurrection
- The Trinity
I highly recommend this book for skeptics and doubters, as well as for Christians who want to add some tools to their apologetics toolbox.
Here are some additional books I worked on in July:
- The History of the Ancient World, by Susan Wise Bauer. I’ve been plugging away at this for several months now.
- Beyond Creation Science, by Timothy Martin and Jeffery Vaughn. This book is as much an argument for strong full preterism (the idea that Jesus already came back in 70 AD) as it is for old-Earth creationism. The authors do seem to be making a good case that the Bible doesn’t teach a young Earth or global flood, with some insights I hadn’t seen before. So far, this book is strengthening both my old-Earth creationism and my Premillenialism. So I guess the authors are being half successful.

This summer, I’ve added a new state (New Mexico) and at least nine new counties, so here are some updated maps.
World map — 10 countries — nothing new:
U.S. map (states) — 46 states — up from 45:
U.S. map (counties) — 900 out of 3109 counties (excluding Alaska and Hawaii):
I believe that this is pretty accurate, especially after about age ten. I can remember, for example, the route my family took for family vacation from Montana to California and back in 1973 when I was twelve years old. I also remember the routes of some long bus rides: Billings, Montana to New Orleans for a national Lutheran youth gathering in 1976 (?), and Bozeman, Montana to Daytona Beach, Florida for a Campus Crusade for Christ conference in 1982.
Since I was in my early twenties, I have kept track of my travels with a highlighter in Rand McNally road atlases. I’m on my second highlighted atlas, and it is getting rather worn.
I was able to create the “Counties I’ve Been In” map by looking at which counties had highlighted roads in the the atlas.
