Thought uses meaning but not necessarily language. Meaning, in the form of a set of possible concepts and ideas, is a nonphysical reality that lay waiting for brains to become smart enough to represent these ideas. Thus, the brain evolved, whereas meaning was discovered, and language was invented - collectively - as a tool to help the brain use meaning.
