Ancient Sumerian civilization is credited with having the first writing, schools, courts, and many other "firsts". The ancient Sumerians thought that blue eyes were a sign of the gods (i.e. the Anunnaki). The Sumerian nobility were blue eyed and fair haired, as most of their busts show. But also in ancient Egypt, arguably one of the world's oldest known civilizations, we find many blonde and fair-haired mummies.
