Do aliens exist? Have they visited the Earth several millennia ago? Could these aliens be the reason why there are places and things that remain a huge mystery even to this day?

For example, these six archaeological finds have remained a mystery even if these are under the scrutiny of the world’s top scientists and archaeologists! It seems that no one could give the most plausible explanation for these things or how they came to be, even if their use/purpose had already been determined.

Although these items might look ordinary and simple for us today, remember that these things belong to the ancient times! How did these ancient people figure out things that would take several centuries, even millennia, before they were actually discovered and put to good use?

It would also seem that some of these items were so far advanced compared with the society or era they were found in that it makes us wonder whether someone from the future or an alien traveled to the place and left these items behind…

Check out these six mysterious archaeological finds:



  • Costa Rica's giant stone spheres are so well rounded and showed signs of grinding that volcanic activity could not be used to explain their size or almost perfect spherical shape. There are balls grouped together while others are scattered around or lined up in what appears to be a territorial mark. Scientists and archaeologists could not come up with a plausible source for these giant balls. Could these be the work of aliens or giants of long ago?
