100 reasons the Earth is old — from Age of Rocks

One of the best current blogs on the topics of geology, young-Earth creationism, and Christianity is Age of Rocks, written by Jonathan Baker. Today he published his 100th post, and commemorated that milestone with a fantastic article: 100 Reasons the Earth is Old. I liked all 100  reasons, and think he could follow this up with 500 reasons the Earth is old when he hits his 500th post. Here are five of my favorite reasons from his list:

6. There is no radiocarbon in old samples, despite claims to the contrary. Geologically old samples of coal, diamonds, and graphite, for example, yield finite radiocarbon ages that are consistent with the expected level of contamination invariably introduced during sample collection and preparation.

15. Quaternary deposits and landscapes are far too complicated to have accumulated in the ~4,500 years following the Flood. Everywhere we look on Earth, we truly find evidence for ~2 million years worth of processes, whether at high latitudes (where we find evidence for repeated glaciations and deglaciations, separated by warm intervals) or in the tropics (where we find thick desert dune sequences alternating with humid intervals) or in the oceans (where 2 million+ years of Milankovitch cycles are recorded in only a few meters of silt and clay) or in the high mountains (where alpine valleys have been carved out by rivers or glaciers, then infilled by coarse sediment, then eroded again, etc.). Flood geologists unanimously assert that the Quaternary period represents the ‘post-Flood’ era, but there is good reasons that conventional geologists ascribe a much longer age: 2.6 million years.

26. Volcanic ash beds (sedimentary tuff), frequently used to date sedimentary rock layers, were mainly deposited in dry conditions. Geologists can distinguish between ash layers that settled in ocean basins (marine tephra) and those that fell over dry land (air fall deposits). When volcanic ash is deposited in flowing water, it produces yet different features identifiable in outcrops, such as grain sorting and lamination. Therefore, not a few volcanic ashes in sedimentary strata contradict the Flood geology scenario, especially because these ash falls take time to accumulate from the air and harden to the point that water-lain sediments can be deposited on top without compromising the structure of the soft ash.

27. The geologic column is no remnant of an ancient flood deposit, global or not. Fine details, in the form of thin layers of alternating clay and limestone, or irregular sand deposits that resemble modern river channels, defy catastrophic explanation, which explains why catastrophism has long been abandoned by research geologists.

29. The distribution of sedimentary rocks is weighted to heavily over the continents, which is the opposite of what we’d expect in a global flood. Floods move sediments from high elevation to low elevation, depositing them in sedimentary basins. During the Flood, the oceans would have constituted the largest and deepest basins, but most sediments remained on elevated continents. How did this happen? Did the laws of physics stop working?

Note that I picked my top five from the first 29; there were just so many good old-Earth evidences to choose from. I could have selected all 100 reasons from the list of 100 reasons!

An equally important list would be top reasons why the Bible does not require anything like young-Earth creationism. A few of Jonathan Baker’s thoughts on the Bible and science can be found on his Theology/Scripture tab.

I said “One of the best blogs” because it is hard to choose between Age of Rocks and Naturalis Historia. Both have been producing top-notch articles.

#26 was near and dear to my heart, as my Master’s degree research involved a study of Quaternary volcanic ash deposits in eastern Washington.

Novare Earth Science — an upcoming middle school textbook by The GeoChristian


Like their secular school counterparts, many Christian schools offer a full year of Earth Science at the middle school level. These Christian schools, as well as home school parents who wish to offer a year of Earth Science, really have only two sources for curricula: secular publishers, such as Glencoe or Holt, or young Earth creationist (YEC) Christian publishers, such as Bob Jones or A Beka. When I taught secondary-level Earth Science at a Christian school, I went with a secular textbook. I figured it was easier to insert a Christian perspective into a secular textbook than it would be to undo the bad science and dogmatic but questionable biblical interpretations in the YEC textbooks.

I was excited this past summer when I stumbled across the web site for Novare Science & Math, a rapidly growing Christian science curriculum publisher. One thing I was enthusiastic about was Novare’s three Core Principles:

  1. CPF-New-300x300Mastery. Typical middle school and high school science textbooks are 800+ page monsters, filled with a lot of interesting stuff, but also packed with more information about more topics than most teenagers could possibly learn and remember. This leads to a Cram-Pass-Forget cycle, which almost all teachers and students can relate to. The Novare textbooks, on the other hand, take a Learn‑Master-Retain approach, part of which involves publishing textbooks that cover fewer topics, with each being covered in more depth.
  2. Integration. Science classes are often taught in compartmentalized boxes. Novare textbooks integrate their subjects with other fields of science, mathematics, and history, with an emphasis on developing science writing skills throughout (no multiple-choice questions).
  3. Kingdom Perspective. Rather than taking the conflict model taken by many Christian educators, who insist that there is a war between science and Christianity, Novare takes an “All truth is God’s truth” approach. As the Novare website states, “There can be no inherent conflict between faith in the One who made the world, and study of the world He made.” Novare textbooks seek to be thoroughly Biblical in their approach to the study of God’s world, which does not negate what God has revealed in his creation.

Here’s what Novare says about the age of the Earth:

Finally, virtually every Christian science textbook publisher is overtly committed to an agenda of rejecting mainstream scientific evidence pertaining to the age of the earth. For both Biblical and scientific reasons, we believe it is time to put this debate behind us. We find the literalistic model of an earth approximately 10,000 years old to be not only not necessitated by the soundest principles of Biblical exegesis, but to be in conflict with the “other book” of God’s revelation: the creation itself. From Psalm 19 and other passages we believe the creation reveals the glory of the Lord. Since scripture and creation both come from the same God, they cannot be in conflict. And when both are rightly understood, they won’t.

I got even more excited when I read that Novare is planning on publishing a middle school Earth Science textbook in time for the 2015-2016 school year. I contacted the owner of the company, and offered my services for reviewing this upcoming product. To make a long story short, the conversation quickly moved from me being a reviewer to being a co-author, to being the author.

Earth Science01

Writing a textbook in a very short amount of time is a daunting task. Not only do I need to present content from a wide range of fields at a level appropriate for middle schoolers, I need to do so in a way that points them to the loving providence of our all-powerful and wise Creator. I am currently working on Chapter 3 (out of about 15), and appreciate your prayers as I write.

Grace and Peace

Around the Web 10/23/2014 — Old Earth textbook, No Ham for dinner, inverted smileys

I’ll break out of my semi-monastic lifestyle for a few moments to pass on some good GeoChristian kinds of links…

Old-Earth Classical Christian Middle School Earth Science TextbookNovare Science and Math, a relatively new Christian curriculum publisher, has announced that they will publish an old-Earth middle school Earth science textbook in time for the 2015-2016 school year. Does anyone want to guess who is writing that much-needed textbook?

Ken Ham Rejects Entering Into “Gracious Dialog” With Old-Earthers — Ken Ham, president of Answers in Genesis and the world’s foremost promoter of young-Earth creationism, has turned down a dinner invitation from the president of BioLogos, the world’s foremost promoter of evolutionary creation (i.e., theistic evolution).

Part 1 — The invitationKen Ham, We Need a Better Conversation (Perhaps Over Dinner?) — BioLogos president Deborah Haarsma, concerned about the level of acrimony among Christians over the topics of evolution and the age of the Earth, invited Ken Ham to have dinner with herself and Reasons to Believe head Hugh Ross:

“All three organizations are also concerned about the departure of young people from the church over origins issues. Each tends to think that the positions of the others are contributing to the problem! But studies have shown that it is the acrimony over this issue that drives young people away. We respect the commitment that Reasons to Believe has demonstrated to gracious dialogue with those of other positions. We completely agree with Hugh Ross that “If we Christians can resolve this issue in a peaceful way it’s going to attract non-Christians to enter into dialogue with us. But if we continue to fight…it turns them off.” Perhaps Ken Ham could join Hugh Ross and me for a friendly conversation over dinner? My treat.”

Part 2 — The rejectionShould I Have Dinner With BioLogos? — Ken Ham compared himself to Ezekiel, warning the people of God against compromise, and Nehemiah, who refused to be distracted by the enemies of God’s people, though he added that he doesn’t consider Hugh Ross to be a personal enemy, only an enemy biblical authority.

“We at AiG are busy “rebuilding a wall.” We are equipping God’s people to defend the Christian faith, and I believe we are doing a great work for God. We are busy being “watchmen”—warning people of those who undermine the authority of the Word of God.”

Ken Ham later wrote that Answers in Genesis “will not, however, send out such a kumbaya message,” by fellowshipping with compromisers.

Part 3 — Hugh Ross respondsAmbassadors for Reconciliation — Hugh Ross is a gracious man, but is obviously disturbed by the discord sewn by those who villainize old-Earth Christians.

“One way we can help people receive our message of reconciliation with God is by modeling reconciliation among ourselves. John 13:35 says, “All men will know that you are my disciples if you love one another.” And yet, although creation beliefs hold a core position in our Christian faith (Hebrews 11:6), no other subject exposes a greater lack of love among believers. Some creationists treat fellow believers with ugly, disparaging disdain.”

“Enough is enough. There are mission fields still to be reached. How can we ask nonbelievers to dialogue with us if we cannot graciously dialogue with one another, if we treat one another as enemies? Unless we make some progress in reconciling our differences, how can we expect to help reconcile a skeptical world to Christ? We are commissioned by God to be His ambassadors. It’s time for us to start behaving as ambassadors.”

It seems strange that someone like Ken Ham can interact graciously with Christians who disagree with him on issues such as eschatology, predestination, baptism, or spiritual gifts without condemning those who disagree with him as “compromisers,” and yet when it comes to a secondary issue such as the age of the Earth (which is an issue of interpretation, not biblical authority), he cannot even have dinner with those who differ from him.

I must add that my limited personal interaction with Ken Ham has been cordial: Do Old Earthers and Young Earthers Agree On Anything?

A Hundred Inverted Smiley Faces — I had moderate success viewing today’s partial solar eclipse with a shoebox pinhole camera and by projecting the eclipse onto the patio with my binoculars. But when I walked back into the house, I was welcomed by hundreds of solar eclipse images on the floor, steps, and walls. Gaps in our horizontal blinds acted as pinhole cameras and projected a multitude of eclipse images:
