Lake Titicaca underwater city ruins
At around 7 minutes in the video they start to mention the rumour and then discovery of an ancient underwater city at the bottom of Lake Titicaca. They found paved roads, terraces, a statue head and a large stone wall over half a mile long!

Although we are very unlikely to find out in our near future, unless local myth tells us, what came first?
Was the now submerged city there before the waters of Lake Titicaca flooded it?
Was the Lake Titicaca water there then Lake Titicaca dried out so they built the city only for the waters to return?
