good find. it is intriguing that all the oldest buildings around the world have interlocking stonework.
I know it is good for resistance against earthquakes. maybe in that time there were severe earthquakes requiring this kind of engineering.
From the article (somebody is thinking along the same lines as you are, Bert):
But these seeming cultural influences, correlations and inheritances are typically written off as the result of great minds thinking alike to solve the common issues. One of the most cited is earthquake or some other natural disaster defense such as tsunami.

You can see in the example above that the remnants of the TuiTonga Empire were in existence when Cook came to Australia and there is record – but we cannot apparently entertain that Egyptians came to Australia because it was just too long ago, too far or that Aboriginals could have also made that journey.
The author also notes that at Gimpi and in other better known places like Luxor and Machu Pichu there are similar styles of stonemasonry which include folded corners, multifaceted stones and insert stones.

Remember how the first time you got a brand new jigsaw together its so precise the pieces almost click together – but when you use a well loved second hand one it’s got more give or wobble because the pieces have worn?
This is the overall fit of the church wall – precise yet not precise. Not the kinds of joins you can see at Cusco where not a razor blade can be pushed in – but complex nonetheless.

The Gympie Pyramid site and their stones are jigsaw pieces within a jigsaw on a worldwide scale
