In some obscure TV show, we learned that space was the final frontier. However, with the Kepler space observatory finding hundreds of awesome new planet every month, we're starting to wonder if that's true. After all, 95 percent of the ocean is still unexplored by humans.
Which got us to thinking: Wouldn't it be ironic if the first proof of extraterrestrial life came from the ocean instead of the skies? With that in mind, we found eight strange things in the ocean that we think might indicate the work of alien hands (or tentacles).
The Baltic Sea UFO
Ancient Underwater City
At the turn of the millennium, oceanographers were doing what they thought was a routine assessment of India's Gulf of Cambay coast. To the surprise of the team and pretty much everyone else in the entire world, they found evidence of a miles-long city stretching out into the water. Although the age of the underwater ruins is a hotly debated topic, some estimates have put it at about 9,500 years old. That's thousands of years before the area was thought to contain people, and would make this among the oldest cities in the world.
