I’m not sure if I posted this video before, but its an interesting watch. Its about a mysterious building like structure under the sea off the coast of an island near Japan. There are of course two sides to this whole story. Some claim its a man-made structure, which puts its creation date at the beginning of the Ice Age; well before civilized societies are supposedly existent. Others claim its the natural fracturing of rock formations from tidal forces. Only time and research will tell.
