Dinosaur Egg

Tonight my young man chose a book about Pyramids and Pharaohs as a bedtime story. As we were busy reading about how inner organs were taken out of the Pharaohs after death, before they were cleaned and dried, so they could be wrapped in bandages and put into the coffin, my young man asked: Where did the first human being come from? Did he or she come from a dinosaur egg? It was time to tell him about the two theories in it's most simple way.
