Humans

Humans are likely the strangest and most dangerous carbon-based lovebirds to inhabit planet APT-3 in the Sol system. These creatures possess next to no defensive or offensive biological traits, such as claws, sharp teeth, or venomous spikes. They have no body-covering coat of fur to keep in heat in low temperature environments. They are so poorly evolved that they insist on walking upright on two appendages despite the obvious fact that it causes spinal damage before the human is aged past a quarter of its total lifetime. However, the one thing that humans may have in their favor is their processing organ. Located in the top of the head near the main sensory organs, human processing organs are abnormally complex when compared to other organisms on APT-3. An unfortunate side-effect of humans' large processing organs is that they almost always become stuck during birth, inflicting extreme pain upon the mother. Humans began to utilize this organ to develop ideas such as "make stick sharp" and "use stick for kill". Eventually, these privative ideas evolved into more complex topics such as "how me kill other human as efficiently as possible". Humans there forth began a constant struggle to develop more and more advanced weaponry and to use it against other members of their own species. It is estimated that humans have ended the lives of 1,000,000,000 of their own species. This goes to show that despite being the most intellectually superior species to inhabit APT-3, they are still too intellectually weak to understand the concept of self preservation, the single most basic function of any life form. It is for this reason that we declare APT-3 and the Sol system to be "mostly harmless", and approve the plans for the system demolition and subsequent construction of Dyson Sphere 648.
