ANCIENT CITIES with ADVANCED CIVILIZATIONS. part 2

TIAWANAKU site is in WESTERN BOLIVIA, South America. TIAWANAKU is one of the most precursors to the INKA EMPIRE. It flourished as a major STATE OF POWER and a MORAL and COSMOLOGICAL CENTER of the REGION.
The ruins are near the SOUTH-EASTERN shore of LAKE TITICACA. The site is at an elevation of roughly 3650 meters (11,975 feet) ABOVE the SEA LEVEL, making it the WORLD'S HIGHEST place in which the ruins were found. The site in which the city was built runs NORTH-WEST to SOUTH-WEST, roughly following the CHOQUEYAPU RIVER in the VALLEYS of the ANDES, and is closer to the EASTERN split of the ALTIPLANO REGION. Therefore it is closer to the famous MOUNTAINS such as the ILLIMANI (means "GUARDIAN of PEACE"), HUAYNA POTOSI,  MURURATA and ILLAMPU.
On the WESTERN side of the ALTIPLANO division is the site of the tallest mountain in BOLIVIA and the 9th TALLEST MOUNTAIN IN the ANDES, the SAJAMA VOLCANO.
The water supply of the city came from GLACIERS and naturally canalized to springs formations inside the city.
The observatory place named KALASAYA was the most important site in the city. The astronomical calculations were made by people who knew the COSMOS' way of communication. They were based on the difference in the obliquity of the ecliptic of the period in which they were living on that specific site, marking the date of the construction and from there came the orientation of every single site that dealt with the protection of the sacred energy lines that came from above and through the sacrifices that they offered and the moral codes they follow, they were able to maintain a covenant between them and the SOURCE.
The EARTH was pictured as a SHIP, sailing on the vast OCEAN of the HEAVENS. They pictured the EARTH floating in SPACE, similar as boarding a ship ready to sail and as it rolls we stand on the deck gazing out to the sea. We rise up on the crest of a wave and our visible horizon increases; when we fall back into a trough, it decreases. The process is regular, mathematical, constant, perpetually changing the angle between ourselves and the horizon.
The axis of the EARTH's daily rotation lies slightly tilted away from the vertical in its orbit around the sun. From this it follows that the TERRESTRIAL EQUATOR (extension of the earth's equator into the CELESTIAL SPHERE) must also lie at an angle to the ORBITAL PLANE. That ANGLE at any one TIME, is the OBLIQUITY of the ECLIPTIC. But because the EARTH is a SHIP that ROLLS, its OBLIQUITY CHANGES IN A CYCLICAL MANNER OVER LONG PERIODS.
They maintained a constant view towards the movements of the stars giving them in advance  the information they needed. Their way of live depended entirely in maintain a clear connection with the SOURCE.
What kind of living beings built it? The only answer is that they had superior use of their bodies and were able to travel anywhere using the charts and graphs that we are not able to understand.
