Here's why:
* Language is a system of symbols: Words, sounds, and gestures are used to represent concepts, ideas, and feelings.
* Language is structured: Grammar and syntax provide rules for organizing words and phrases into meaningful sentences.
* Language is shared: It allows us to communicate with others and understand their thoughts and ideas.
While other forms of expression exist, such as:
* Nonverbal communication: Body language, facial expressions, and tone of voice.
* Art: Painting, music, dance, and sculpture.
* Actions: Behaviors and deeds.
Language remains the primary tool for expressing complex thoughts, ideas, and arguments.
