Thousands of years before the Inca, a megalithic civilization was founded at Lake Titicaca which spread 500 miles to Cuzco, following a global flood that destroyed the Earth in 9000 BC. Its architects — Viracocha and his seven Shining Ones — disappeared as mysteriously as they appeared, yet the legacy of temples they left behind still baffles the modern mind.
