Remaining+Mysteries

Three mysteries that are still being discussed are "I wonder why they had all these clay balls", "What were they eating for dinner ten thousand years ago", and "What do these murals mean?" They found that they used mud brick ovens to cook their food and animal hide to hold water for their food. The murals have pictures that tell stories like a volcano and leopard skin. A clue we have found about the clay balls was they were found by piles of ash and charcoal.
