Yeah, I do not know why OP would imply that. The brain does actually parse. In terms of language processing, the term "parse" may refer to the mental process of syntactic analysis, in which case the brain analyzes the grammatical structure of a sentence to comprehend its meaning. Besides that, there is auditory parsing of sound patterns, along with visual parsing of visual scenes to recognize objects, shapes, and patterns.

Sure, the brain does not follow the same principles of formal grammars used in computer science, but I think the term "parsing" still applies.
