6. Giant Stone Sphere Discovered in Bosnian Forest
Location: Bosnia’s Zavidovici
Year Found: 2016; Estimated Value (Iron Content Value): $3,200*
The formation of this 35-ton, ten-foot-wide stone ball has caused many academics to wonder if Mother Nature or a vanished civilization created it. What may these people or aliens have used it for, if the former is the correct response?

In 2016, the enormous sphere was found outside of Zavidovici, Bosnia. Semir Osmanagich, the person who discovered the prehistoric ball, gained notoriety as the “Bosnian Indian Jones” thanks to it. Given that the sphere probably contains a lot of iron, it might be highly valuable. The greatest structure of its kind in Europe, if the stone is man-made, may hint at complex civilizations from the past that we now know very little about.
