We may have a genome that is only two percent different from that of a primate, but the result is nothing short of a singularity. Chimpanzees may be amazingly advanced mammals, with complex social systems and the ability to use sticks as limited tools, but... Our two percentage points gave us Shakespeare, the Italian Renaissance, jazz, the wheel, skyscrapers, the Apollo Program, agriculture, global telecommunications networks, gunpowder, the Cold War...

Even an alien civilization that may seem like gods to us won't confuse us with our genomic neighbors.
