The investigation took a new turn when my informer suggested the study of other ancient world sites, and with the discovery that the same building issues had been resolved in the same manner, on sites thousands of kilometers (and supposedly hundreds, sometimes thousands, of years) apart. The argument frequently put forward - that "Homo Sapiens, being the same the world over, finds the same type of solution for the same type of problem" - leaves modern day architects and engineers perplexed. One such is Chris Wise, one of the world's leading structural engineers.
Admittedly, the similarities are more than disconcerting and one must accept that in the past, blocks of complex shapes weighing from 30 to 200 tons - hardly feasible today - must have been handled quite easily, and that it was possibleto assemble them with absolute precision without using cement, in such a fashion that they would withstand earthquakes. Other points in common between these sites add to the confusion: mummification, developed medicine, deep knowledge of astronomy, pyramid construction, hieroglyphic or ideographic writing, the lack of written records of the methods used...
Another remarkable fact, and not the least, is that we can observe and verify with GPS the alignment of ancient sites over thousands of kilometers. Either the people of the time knew nothing in the existence of other similar constructions and we therefore conclude that the sites are aligned by chance, or they knew the existence of other sites - which would explain the sites' similarities. But the question remains: how would they have been able to align their sites over thousands of kilometers, in some cases separated by oceans, in such a technologically underdeveloped past?
