@Free: I believe that "Earth" only existed in the Sonic X continuity. As for the term Mobius, that came to be because of a blunder SEGA of America made when they confused the first half of the term "Mobius Stripes" as the name of Sonic's world, when in reality "Mobius Stripes" was actually referring to a shape that was present in Sonic 1 (basically those twist and turn-like tunnels that you run into).
