The job of an archaeologist is full of excitement as they never know what they might find. However, not all discoveries can be easily explained.

The Glow Alien Tablets found in France in 1924, for instance, continue to be a subject of controversy. While some believe they belong to an unknown civilization, others claim they are nothing more than an elaborate fraud. Similarly, the Thornborough Henges in England, made around 6,000 years ago, remain a mystery as no one knows why they exist.

The GaN tia Temples in Malta, estimated to be 5,600 years old, are believed to have been built by giants who ruled the land. The Norra meet su Adachi, a 15-foot-long sword in Japan, has also prompted rumors of a giant warrior race. Finally, the statues on Nuku Hiva Island in the French Polynesian Islands look humanoid but not quite human, leading some to believe they represent reptilian visitors.
