Ok then are there any genes that could be view as  human only genes and if so why? [^]

What you do speaks so loudly that I cannot hear what you say.

How could you possibly know?  You can only know that a gene is uniquely human if you can demonstrate that absolutely no other living entity has that same gene - but how would you know that without knowing every gene in every living entity on the planet.  We cannot even say that we know every type of life on Earth (on the contrary, we keep coming up with life forms we had never befor known about), and we have only sequenced the genes for a very small handful of thsse species, and even there, we don't really understand much of the information we have obtained from sequencing the DNA.

Nature has a tendency to reuse the same building blocks in different ways, so even where a protien exists that may perform a unique function in humans, it is very likely that the very same protien is used in a very different way in another living organism.

...and this is the practical demonstration of evolution: same building blocks, receptors, enzyme and so on.  Sometimes similar proteins (70-80% common sequence) derived by mutation and selection have different functions...
