Life without language would be problematic

Language allows us to express our selves in a certain way that might not otherwise be able to do. It allows us to give accurate instructions without physically demonstrating them. It allows us to quickly and easily tell what happened in a specific scenario. And it helps us to learn from our own mistakes. This is perhaps its greatest function. The oral histories and legends that were passed down through the ages, and then coded in written language, allow us to learn from other mistakes before we make them ourselves.
