Scientists in Turkey have found a 13,000-year-old calendar.  Here, a huge stone pillar is carved with what scientists believe is the world's oldest solar and lunar calendar.  It is speculated that the calendar may have been created to mark a catastrophic comet attack.  
 Archaeologists have found some carvings carved on stone at Gobekli Tepe in southern Turkey.  Göbekli Tepe is the famous archaeological site of southern Turkey known for its large number of temples found.  The paintings found on these are a center of attraction for the world.  A study published (via) July 24 in the journal Time and Mind refers to a 13,000-year-old calendar.
