The archaeological work carried out made it possible to find a huge stone ball on the territory of Bosnia, in a place called Zavidovichi. Its estimated age is not less than 15,000 years.
Such artifacts were named - concretions. Such finds are occurring literally all over the world. But the Bosnian stone is the largest of the discovered stones and its weight is equal to thirty tons, and it has a girth of three meters. According to the official version, these formations are natural and do not carry any historical value.
But some researchers disagree. In particular, archaeologist Semir Osmanagich believes that these stones are nothing more than fragments of an ancient civilization, which were created by them for purposes unknown to us. After all, the creation by nature of an almost ideal shape of balls is almost impossible. The analysis of the upper layer of the sphere showed a high iron content, which further reduces the likelihood of the natural origin of the find.
Archaeologist Semir has been researching for over 15 years and has observed similar artifacts on absolutely all continents in the most inaccessible places. And they are all remarkably similar to each other.

Modern archaeologists do not even try to understand and study this artifact. After all, if the fact that these formations are of artificial origin is confirmed, then it will be necessary to revise a whole layer of history and recognize other artifacts that are also ignored by modern science.
