We distinguish ourselves by having language. Religion is a big language user - it creates language by converting our inner re-representations into spoken utterances. The rationalist option focuses on the relation of language to thought; thus its answer to why we use language is: for formulating thought. Thinking in language may just be a reflection of language on thought, while language originated in not so thoughtful communication. Communication with language would thus seem to be a secondary product of a language for thought. Language is a semiotic, communicative system based on some more basic symbolic faculty; this symbolic faculty creates re-representation where was simple representation; language further contributes to that re-representation.
