alt Hacker Newshumans reasoned before language but lacked the ability to store and transmit it. Later advanced humans developed abstract reasoning once lingustistic library became sufficiently description of reality. But this is not how we reason from first princples.
Language is one of our tools we developed to STORE reasoning, not create it. LLMs excel at uncompressing and interpreting that stored reasoning.

That's an interesting supposition. Are you assuming language didn't exist before it was written? Language and meaning are, if you squint, pretty ancient and have roots in things like birdsong. It could be that ur-semantics predates our species as a whole.
