Ancient cities discovered off the coast of Cambay in India demonstrate remarkable building capabilities of an ancient people using giant granite blocks described to be fit together like sugar cubes. Two sites found date as far back as 7,500 BCE with one turning up pre-Harappan artifacts.
Fifteen miles away, the second site known as the lost ruins of Mahabaliipuram, features a completely different architectural style, lacks any sort of artifacts found as the first, and has not revealed any inscriptions to help identify it. Controversy over both sites dismisses the wooden pieces recovered by dredging and claims the pottery shards do not show any signs of being Harappan and that they must be natural formation otherwise known as geofacts. To some, the underwater images of the sites reveal distinct man-made structures believed to be the ancient cities of Khambhat and Dwarka. There is a legend found in an ancient Sanskrit text describing Lord Krishna leaving Earth after a great battle with UFOs and the city of Dwarka sinking into the sea.
