Earthling

From Slackerpedia Galactica

Earthlings are surprisingly carbon-based life-forms who live on the Earth. The logically named Earth is surprisingly not approved by the IAU, the object Sol 1 c name could be changed in the future. Earthlings are like stars but dimmer. Earthlings have often been nicknamed "Humans" and sustain blood transfusion in their cores.

In certain other publications, they are considered - like the Earth itself - "Mostly Harmless."
