Are you sure you were paying attention when you read it, because that's not what happens in the book. For example, Rocky needs essentially an environmental suit to survive in an atmosphere suitable for humans, due to his planet having much higher pressure and temperature. Communication is established over some time based on engineering principles, which are universal properties of the universe and a classic sci-fi trope for communicating with very different alien species.
I thought it was a pretty good book overall. Lots of interesting ideas and detail. Strong characters, at least for the protagonist and Rocky.
