The wonders of ancient civilisations

An ancient pyramid built 4000 years ago in the Andes is a sophisticated clock linked to movements of the stars, enabling priests to tell farmers that it was time to plant crops, expect flooding of rivers etc. To the peasants it must have seemed like magic - but it was all a con - the priests were able to interpret the alignments of the stars with the pyramid - but it shows how advanced these so-called primitive cultures were. Amazing.
