A very simple question for all of us, how much do we really know about our beloved planet Earth? Our planet is way bigger than we actually know. Did you know only 5% of the world’s oceans have been explored to date and there’s still 12% of the land on this planet that has not been seen by human eyes? You can imagine what all discoveries are still left to be found. However, what has been discovered so far will make your jaws drop. Every day, archaeologists around the world are making discoveries that are stunning and bizarre at the same time.

Here are some 40 amazing archeological discoveries that seem to be from some fictional world but trust us they are from this planet. For example, the infamous Nazca Lines in Peru. We have no idea, how could humans from that time created such large works of art on the earth’s surface that too, without seeing what it would look like from the sky. We can’t say if it is the work of human or some aliens. It is up to you to decide.

Mysterious Stone Spheres

The archaeologists discovered these peculiar giant stone spheres on the Diquis Delta in southern Costa Rica. This amazing discovery continues to amaze the modern science to this day. Dating back to 600 A.D, they are locally known as Las Bolas and are said to be the monuments from a pre-Colombian civilization. So, what was their purpose? Some experts believe they were used for astronomical purposes. While others believe they were signs that pointed the way for the people for reaching other locations ( maybe reading maps then was difficult). For whatsoever reason they were built and used, we may never find the real truth behind it because the Chibchan people ( the creators) who used to live in the area vanished from the surface of the earth after the Spanish conquest ( at least they could have asked them)
