Uncovered near Sanliurfa, Turkey, the earliest known ancient ruins called Gobekli Tepe carbon dates to around 9,000 BCE and features carvings and a language that may also be the earliest known form of writing. The ruins are formed in rings of megalithic blocks estimated to weigh 7 to 50 tons each, and are intricately carved with animal figures. Theorists state the megaliths were placed by piling sand up then making a platform. Further theories suggest the opposite, that the megaliths were purposely buried in order to hide them, or that blowing sands over the years covered everything up. It's estimated that another 50 years of digging could finally uncover the entire site. So far there are no sources explaining what the symbolic language means or who was responsible for creating Gobekli Tepe. One significant find, though, is a sphinx appearing to be later replicated ~7,000 years later in Egypt on a grand scale.
