What you say is vital. I cannot disagree.
We started (12 years ago!) with the 'usual astroarcheological stuff' but it rapidly got left behind by the internal light/shade aspects, which have their problems as you rightly point out. But as the years, and especially the last two, went by, the way the light and shadows it casts upon itself, throughout the day, and the year, play upon the worked stones became simply too astonishing to be dismissed as happenstance or co-incidence. It is like a giant sundial, a Solar Construct of great sophistication in its calendrical accuracy.
We make bold claims, but the evidence is compelling.
The time has come to abandon the "Anachronistic Archeological Paradigm"; the idea that the people who built and used this thing were witless savages.
And just to tickle the fancy, we have found a possible 'carving' that bears a remarkable resemblance to the Sumerian symbol for 60.
I am grateful for your interest.
