Communication requires understanding the meaning of what our senses perceive. For that you need symbolism and understanding, something totally unexplainable by materialism.

What you do not understand is that our bodies, and those of higher organisms have a dual nature. On one hand they are run by proteins, on another hand they have a nervous system and a brain that runs on electrical impulses.

Your argument sounds like materialism to me. Here is a dictionary definition of materialism:

a theory that physical matter is the only or fundamental reality and that all being and processes and phenomena can be explained as manifestations or results of matter.

No. Symbols are totally immaterial and without the non-material correlation of one thing with another life would be totally impossible. DNA itself is a symbol. It is an abstract language which is read in threes by DNA and interpreted as amino acids. Symbols are a sign of intelligence and a total disproof of materialism.
