Talk:Site-Zero/@comment-35794467-20180605222604

While the assertion that Site Zero is possibly an alien terraformer certainly has merit, I've always seen it as simply a military outpost left behind by the former inhabitants of Earth. These inhabitants, who may have been native to Earth or may have colonized Earth in the ancient past, built Site Zero to protect their world from invaders; Nexus (which I see as an advanced computer or Artificial Intelligence) would deploy the T'lan to the surface to protect the world. So, millions of years ago, the creators of Site Zero either went extinct or simply left Earth to colonize other regions of the Galaxy and left Site Zero behind, with Nexus partially shut down, but still having some control over the functions of Site Zero. Then, Humans come by and activates Nexus, who percieves them as invaders and deploys the T'lan to wipe them out. To me, there's no great mystery.
