We likely learn/generate language in an auto-regressive way at least conceptually similar to an LLM, but this isn't just self-contained auto-regressive generation...
Humans use language to express something (facts, thoughts, etc), so you can consider these thoughts being expressed as a bias to the language generation process, similar perhaps to an image being used as a bias to the captioning part of an image captioning model, or language as a bias to an image generation model.

My point however is more that the "thoughts being expressed" are themselves being generated by a similar process (and that it's either that or a God-given soul).
