Ancient Sunken City Discovered Off Shores of Cuba. Maybe

King Africa writes "Explorers using a miniature submarine to probe the sea floor off the coast of Cuba said on Thursday they had confirmed the discovery of stone structures deep below the ocean surface that may have been built by an unknown human civilization thousands of years ago. The explorers said they believed the mysterious structures, discovered at the astounding depth of around 2,100 feet and laid out like an urban area, could have been built at least 6,000 years ago. That would be about 1,500 years earlier than the great Giza pyramids of Egypt. " The BBC has a bit more substantative article on this as well - but I do wonder how they assigned the date "of at least 6000 years ago" to this.
