The genomes of humans beings and chimpanzees are nearly identical so why are we humans and chimps so different

The reason why humans and chimpanzees differ even if they share almost the same gene because the gene was not the reason of how both should be similar but because of how they work as the genes of a human and a chimpanzee may be the same but the way they work are different that enables the brain of the chimpanzee and humans to be more different because the genes of a person is close in networks than of the chimpanzees.
