Hundreds of millions and possibly billions of stone artifacts sit just under parking lots and homes in Kathu, South Africa. Artifacts in this area were examined a few years ago in a vacant lot scheduled to be developed into a shopping plaza. Explorations in this lot revealed a very dense collection of artifacts referred to as an “astronomical” collection in a report by a South African museum commissioned to survey the site and make recommendations about further development.
How many artifacts were found? In just a few meter-square sample pits over a several acres, archaeologists collected 10s of thousands of stone tools and products of tool making. The archaeologists estimated that there are on average 900 artifacts per 100x100x10 cm volume of material in this area with much of the area up to 2 meters deep in artifact rich soils. This high concentration of artifacts along with available source rock in outcrops nearby suggests that long ago this was a tool making center.
When I first read about this incredibly rich stone tool site it got me wondering: just how prevalent are stone tools? I really didn’t know, but as I researched this site further and several others from around Africa and the Middle East I was absolutely stunned by the sheer volume of stone tools that have already been found. Then I asked myself the question, just how many stone tools or artifacts could there be in the soils of Africa? My back-of-the-envelope calculations seemed so ridiculously large that I found it difficult to believe at first.
For example, the Kathu Townlands vacant lot site which was surveyed covered a couple of acres. In just that area alone I estimate there must be between 36 and 360 million artifacts. Those are astounding numbers. But then consider that large numbers of artifacts have been found outside this lot. The total area covered by this stone tool manufacturing center is now thought to extend over some 25 hectares (61 acres). Using much more conservative estimates for the density of artifacts and depth to which they occur, I still come up with an low-end estimate of 1 billion stone artifacts in these soils.
But the gaudy numbers don’t stop there. Within a few miles there are several other high density stone artifact sites not to mention hundreds of other locations in South Africa. And these are only the sites that we know about. There are almost certainly ore sites left to discover than have already been discovered.
Billions and billions of artifacts and millions and millions of tools
Stone artifacts in South Africa alone must number in the tens of billions if not more. Of course, most of these are not completed stone tools. Stone artifacts include all the shards of stone tool production. The number of complete stone tools would be a small percentage of these artifacts. Even so, we are talking about tens of millions of stone tools. The more I read the more is suspect that I am much more likely to be underestimating their abundance. And this is just South Africa. Stone artifacts are found abundantly throughout Africa.
Maybe the best evidence of how common stone tools and other artifacts are in South Africa can be found in the final conclusions of the report by the McGregor Museum that I mentioned earlier. Although they only were able to examine a tiny fraction of the material at this site they conclude: “we recommend that the permit for destruction of the remaining archaeological deposits of Erf 5116 be approved.” They argue that they collected enough material to be able to study the tool technology and characterize it in this place and time in history and no more material is necessary. Even though these tools are thought to be a half a million years old getting more material isn’t considered valuable enough to stop most of it from being paved over. A museum giving permission for development and not fighting for protection should be enough to convince you that stone artifacts are incredibly common.
The Stone Age, Creationism and Adam
I am rolling around some ideas for a series of posts in which I would introduce you to some of the more famous Stone Age sites. We would look at the context in which the artifacts are found and ask how those tools can be explained in a variety of faith traditions. Here are some particular questions that I am hoping address as I do my research:
- When did the people live that produced all these stone tools?
- How do young earth creationists (YECs) fit the Stone Age into their post-flood timeline?
- Who produced these tools and when did the live?
- For evangelical Christians, what challenges, if any, do these tools present for out understanding of a historical Adam?
- If there had been a global flood would stone tools be expected to be found in the geological column?
- Are all stone tools produced the same way or are there different stone tool production technologies?
