12 most incredible finds that scientists still can't explain

We love a good mystery. As fascinating as it is when an archaeologist pulls something out of the ground and is immediately able to tell us all about what it is, and what it says about the people who came before us, we're much more excited when they come across something they can't explain. Even with all our current technology, the amount of information we're missing about our ancestors and the way they lived is startling. Perhaps we'd understand them a little better if we correctly understood the purpose of the strange artifacts you're about to see in this video!
