e.t. come home

According this this article, we silly earthings are about to drop off the radar of the aliens that are trying to find us. Question: what aliens? Am I missing something, or have we yet to find any credible evidence they exist? And, if they do, why are we so eager to make sure they find us? We have a hard enough time getting along with each other; I can't imagine how many ways we could botch up inter-planetary relations.

By the way, the article implies it's all the cable companies' fault. First they make us sit in our houses all day waiting for service calls and now they are making all the aliens go away. That's so like them.
