It's well known that the Inca took no credit for the megalithic structures when questioned by the Spaniards. A cursory look at the two types of architecture on the video clip will tell you that they were not built by the same people.
In the year 1523, local American Indians told the Spaniards that those gigantic buildings where build in one night, long before the Incas. Another legend tels that these cities where lifted through the air by the sounding of trumpets.
Part of the site of Tiwanaku is known as Puma Punku, in the Bolivian Andes. The word "Puma Punku" is Aymaran and translates to “Door of the Cougar”. Here there are huge stone blocks (the heaviest block is weighing 440 tons) which where supposedly part of a huge ancient but architectural advanced construction.
