I'll bite. Why must the first self-replicating molecule have contained a plan to build something? As far as I'm aware, all that is required for evolution to begin is something that can replicate with some rate of imperfection sufficient to create new variations. From there, selective pressures are sufficient to promote those variations which confer a reproductive advantage. There need be no plan, no intent, no communication. Just replication.
All of your other assumptions about language, encoding, communication, etc., are all predicated upon this basic assumption of a plan or intent in the first molecule, so I'll leave them aside for now.
