An almost 7,000-year old stone tablet found in Bulgaria bears carvings that might turn out to be one of the world's oldest inscriptions, a prominent Bulgarian archaeologist said Thursday.
"These signs are unique and apparently bear a meaning," Nikolai Ovcharov told a press conference. Ovcharov said he had received the tablet from a private collector who had unearthed it 20 years ago.
Seems rather dubious, due to the lack of context.
