Introduction
For those who have followed me for some time, you know that I take a strong stance on the importance of defending the Christian worldview in its specific claims about reality, as opposed to only defending general claims. For those who are not familiar with my reasons for this position, please see my posts here and here. One of the theological debates that I defend specifically is a particular view on creation. I take the old-earth creation (OEC) position that holds to the literal historicity of the records of Genesis 1-11. I came from a position of young-earth creationism (YEC) but changed due to the lack of scientific evidence supporting the view and the complete compatibility of OEC with Christianity. A couple years ago, a prominent YEC leader (Ken Ham of Answers in Genesis) debated Bill Nye on the scientific status on YECism. Ham constantly drew a distinction between "observational/operational science" and "historical science" to say that what happened in the past cannot be known. I wrote a post last year critiquing this philosophy of science and provided a followup clarification on my position (here and here, respectively).
Since then I have read and reviewed one of the foundational works on the philosophical distinction (Origin Science: A Proposal for the Creation/Evolution Controversy by Norman Geisler and J. Kirby Anderson). My previous posts dealt with the distinction as presented by Ken Ham (and many other YEC proponents); however, today I want to deal with the distinction as presented by Geisler and Anderson. There is a wide chasm between the two understandings, and if Ken Ham is getting the distinction from the work of Geisler and Kirby (or someone who agree with their distinctions), then he has misunderstood the distinctions. My goal is to explain the distinctions made by Geisler and Anderson and show how they have been misunderstood by Ken Ham and other YEC proponents. I will also show that the rejection of circumstantial evidence in Ham's understanding necessarily undermines the presuppositional grounding of knowledge of all events recorded in the Bible, which is what Ken Ham promotes in place of a circumstantial, evidential approach to discovering the mechanisms, timing, and purposes of creation.
