Why do we need a programming language?

We need a programming language so that machines operate and function like they were supposed to do. We need a programming language to create programs that run effectively and efficiently for users/people. Another reason we need a programming language is to have a standardized way of building and making code for software. Programming languages are usually the foundation of programs like Firefox or Google. That is why programming languages are need, especially up to date ones where the demand is high for programs that we have not even imagined for or need really badly.
