The ancient Greeks believed that our galaxy was created when the goddess Hera spilled some of her milk as she was nursing the baby Hercules. Each drop became a star in what we have ever after appropriately called the Milky Way. Likewise the Egyptians, the Hindus, and the Sumerians assigned milk a central role in their creation stories. Milk-based creation myths can be found in many cultures around the world and you might regard them as merely entertaining and fanciful stories, as I always have.
