The Dropa Stones

Back in 1938, archaeologist Dr. Chi Pu Tie made an unusual discovery during an expedition into the Baian-Kara-Ula mountain range in China, where he found a series of tiny circular stone discs that shared eerily similar markings to phonograph records — but dated back 12,000 years. There were 716 discs in all that measured up to 1-foot in diameter, and each disc carried two grooves that originated from a hole in their center in the form of a double spiral.

These grooves contained tiny hieroglyphics that were only distinguishable by a magnifying glass. After studies at Bejing University yielded no results, the discs were given to a man name Tsum Um Nui. After nearly 4 years, Tsum Um Nui managed to decipher the hieroglyphics and said they revealed a fascinating story of an alien spacecraft that crashed landed to Earth. He says that the passengers of the ship were unable to repair their vehicle and were forced to adapt to the conditions on Earth. His findings were published in a professional journal in 1963, but were (and still are) met with criticism and disbelief.
