NH Notes: Mars Takes Another Hit, Wishes it had an Atmosphere Like Earth

There is much interest in determining the likelihood of future asteroid and meteorite impacts on Earth.  It is very difficult to estimate the probabilities of such events but we can learn something by looking to one of our solar system neighbors – Mars.  Because the surface of Mars changes so slowly new impacts there can […]

Stone Artifacts From the Deep Sahara: Creating Problems for Young Earth Creationists


In our tour of African stone artifact collections, we now travel to a remote portion of the Sahara Desert in southern Egypt.  Stone artifacts are probably abundant in nearly all parts of northern Africa, but they are not easily found everywhere.  The shifting sands of this forbidding desert have buried most of the evidence of […]

Thousands of Stone Age Artifacts and Fossil Bones: A Story of an Ancient Butcher Shop

I have been writing about the immense number of stone artifacts that are preserved in the sands, soil and rock layers of Africa in response to the young earth creationist’s rejection of their existence or at least of their abundance.  I was reminded that I had written about stone artifacts a few years ago that […]

Billions of Stone Artifacts: Witness to the Ancient Occupation of the Saharan Desert


The Nubian Desert, which encompasses 400,000 square kilometers of the eastern portion of the Sahara Desert, contains a rich assortment of stone tools and products of Stone Age industries.  Scattered stones among the drifting dunes speak of a time long past during which this land was covered by grassy hills and ungulates, lions, and hyenas […]

Trillions of Stone Artifacts Redux: A South African Test Case of YEC Chronology


Recently, Dr. Terry Mortenson of Answers in Genesis responded to one of my articles (Trillions of Stone Age Artifacts: A Young Earth Anthropology Paradox) which claimed that the presence of trillions of stone artifacts scattered across Africa is a significant problem for young-earth creationism (YEC).  He questioned the fact that so many artifacts could be produced even […]

Dogmatic Assertions of Expertise: Having Faith in Flood Geology

Everyone is an expert in something but they can’t be an expert in everything.  At some point we all have to rely on the expertise of others to guide us through our lives.  I am a biologist, however, the vastness of the field of biology leaves me in the position of deferring to the knowledge of […]

Answers in Genesis Struggles to Make Sense of Vast Numbers of Stone Age Artifacts

Selected artefacts from KAM1. (1) Conjoined Levallois flake with bidirectional flaking pattern; (2) Levallois flake with centripetal flaking pattern; (3) broken Levallois flake,possibly a point, with unidirectional flaking pattern; (4) broken Levallois flake, possibly a point, with bidirectional flaking pattern; (5) Levallois flake with centripetal flaking pattern; (6) centripetally prepared preferential Levallois core; (7) double side retouched point; (8) side retouched flake; (9) refitted single platform core and flake; (10) refitted core management flakes; (11) conjoined blade. Eleanor Scerri in Scerri et al. (2014).

How many stone age tools and associated artifacts are there and what are the implications of their existence? I raised those questions in a series of posts in the past year (Trillions of Stone Age Artifacts: A Young Earth Anthropology Paradox and How Rare are Stone Age Artifacts? A Visit to a Stone Tool-Making Center […]

Can You Spot the Difference? The Slowly Changing Surface of Mars

The restaurant kids meal activity "spot the differences"  has many android app versions now including this one by ??.   I expect it would take a keen eye to notice the difference in a 6000 year old photograph of Mars and one taken today.

Below is a picture taken by the Curiosity Rover on Mars last week.  Had you been on Mars 6000 years ago at this very location what do you think it would have seen?  What differences do yo think you could spot between then and now? I have zoomed in on one section of this rock […]

Is Historical Science Reliable? An Exploration of the AiG “Origins” Science Label


Young earth creationists frequently speak of two kinds of science which they refer to as “origins” and “operational” science.  These terms are possibly akin to what scientists may call “historical” and “experimental” science.  What is this “origins” science and how does origins science play a role in the discussion of the Age of the Earth? […]

Reflections on a Young Earth Creationist’ Approach to Scientific Apologetics

Yours truly looking reflective while a member of a panel discussion at a conference last week in Guatemala. I am probably just having a hard time answering an off-the-wall question posed by an audience member. Fortunately I was allowed to speak at this conference and had a wonderful time with a very engaging audience.

A few weeks ago I was a scheduled to present several lectures as part of a course offered by Veritas Theological Seminary in Santa Ana, California.  The course title was Scientific Apologetics: The Age of the Earth.  The course was split 50/50 between speakers from Solid Rock Lectures including myself, and two prominent employees of Answers […]
