In this third installment of the search for a sensible rationale for the existence of monuments whose designs have intrigued humanity over the centuries, the author challenges his previous findings and expands his analysis to include one of the most enigmatic of ancient monuments: Göbekli Tepe.This new study takes us beyond the traditional musings regarding the sun and the moon shadows interplay with ancient structures by providing geometric and astronomical analysis based on analytical data collected in the last five years. The challenge to his own data and analysis brings him to the discovery and proof of the role the solar system played in the design, alignment, location and possibly the time in history the monuments were designed. Göbekli Tepe and other sites tell that story.
