Two Million years ago when people still believed in gods. The gods made a rule that if a male baby is born a rib is brought out of the left hand side of the baby’s body as a sacrifice to the gods, and if a female baby is born a rib is brought out from the right hand side as a sacrifice to the gods. Many years past and the people got tired of the rule of the gods and made a plan that their baby’s did not have to feel pain when they are born. The bravest of them all said that if a baby is born the rib of a lamb is brought as a sacrifice to the gods.
Two million years past, scientists discovered the ribs of animals and babies, put it together to form a sphere of bones in a museum.
