A remarkable find in Mexico has alien hunters excitedly discussing the possibility that new evidence for extra-terrestrial life forms has been discovered. Alien enthusiasts have found what they think are some strange artifacts and sculptures near a cave in Mexico that are believed to be about 5,000 years old.

The sculptures are strange because they are of creatures that have very large eyes and an elongated head, much like the way aliens have been portrayed in popular culture and certainly unlike anything here on Earth. They think this is evidence that aliens visited our planet thousands of years ago, and the sculptures were either made by the aliens or humans did after encountering them.

The speculation really took off after a YouTuber posted a video that shows what the sculptures and artifacts look like, which quickly went viral online. The video has been viewed more than 60,000 times as of Jan. 27, and it is embedded at the bottom of this post.

“Many will know the Klaus Dona Artefacts,” reads the description on UFOmania’s video. “There are Tons more where they came from. More and more locals and farmers are showing their private Artefacts. Fortunately they did not give their Artefacts to the Smithsonian Institute and the like for further Analysis.”
