10 Mysterious Photos That Scientists Still Can’t Explain

The Baltic Sea UFO

For decades, people have whispered about the possibility that human life didn’t start on Earth. Belief in UFOs and alien life forms skyrocketed, despite little evidence that they exist. When Swedish treasure hunters used sonar to scout out the bottom of the Baltic Sea, they may have gotten more than they bargained for.

An outline of what looks like an alien craft was clearly visible in their shot. When they tried to get closer to the strange object, their electrical equipment began to fail and they had to resurface. No scientist has been able to disprove this photo, and the Baltic Sea Anomaly remains one of the most bizarre discoveries in recent years.
