These are the artifacts that many believe should have never existed, or for which we have no satisfying explanation. There are many remarkable ancient objects and discoveries in this video that could re-write history as we know it. Theories about their origins can be scientifically sound, beyond crazy, and everything in between. From sunken cities to pictures depicting humans and UFOs, all the way to pyramids of prehistory – take a walk on the weird side of archaeology no one dares to include in the books.
An out-of-place artifact (OOPArt) is an artifact of historical, archaeological, or paleontological interest found in an unusual context, that challenges conventional historical chronology by being “too advanced” for the level of civilization that existed at the time, or showing “human presence” before humans were known to exist. Other examples suggest contact between different cultures that are hard to account for with conventional historical understanding.
