Every now and then, archaeologists stumble upon objects that are so strange they cannot be easily explained. These very ancient artifacts raise the questions of how such advance technology existed in those times. The authenticity of these ooparts are generally already accepted, but many scholars questioned how such things could have existed thousands of years ago. Proponents point to the discovery of mysterious, ancient objects in remote locations devoid of human life as evidence of advanced civilisations lost to history.
These are objects of historical, archaeological, or paleontological interest that have been found in a very unusual place, are judged to be too advanced for their time, or that demonstrate the presence of humans before they were known to exist. OOPArt has been used to support sacred views of history, ancient astronaut theories, and the belief in extinct empires that had a more advanced knowledge or technology than we have today.
