Chapter 1. Why did we have to wait 40 years -- Chapter 2. Why did we choose Pumapunku/Tiwanaku and not Cuzco and Sacsayhuaman -- Chapter 3. The preliminaries of the expedition and the question about the extraterrestrials -- Chapter 4. Understanding the history of Tiwanaku / Pumapunku -- Chapter 5. First day in Tiwanaku.

This book presents the study on Ancient Geopolymers in South America and Easter Island regions, exploring the artificial nature of the volcanic rocks used in the construction of Easter Island's statues. Contrary to the belief that the statues were carved and transported, Davidovits suggests they were made on-site using geopolymer technology. He proposes that this knowledge came from Amerindians from the Andes, specifically the Tiahuanaco region near Lake Titicaca. The book is divided into two parts: the first examines geopolymeric artificial stone technologies in the Andes, and the second establishes a connection between these technologies and Easter Island, 3,700 km away. Davidovits' research includes geological expeditions, SEM analysis, petrography, and a comprehensive review of international literature. It is intriguing to observe that in both cases, Pumapunku /Tiwanaku in the Andes and Easter Island, volcanic rocks are involved which contain biological carbon. These discoveries undeniably support the theory of geopolymeric artificial manufacturing, challenging traditional archaeological views.
