3. UFO wreckage
In the 1970’s, a fragment of metal was found in Romania, 33 feet under the ground between two human bones. The analysis showed the object to be a piece of aluminum, estimated to be 250,000 years old. This wouldn’t be so shocking if not for the fact that mankind did not discover and start using aluminum just 200 years ago! Furthermore, its substances can’t be combined with the technology on Earth, which is why is assumed that this is work of the aliens.
The bones are aged between 10,000 and 80,000 years old, and historian Mihai Wittenberger says that this metal was part of a World War II German aircraft. But this still does not explain its age.
