User blog comment:KrusH HsurK/Earth, Capital of humanity, but lacking of its own capital?/@comment-92.18.158.151-20120509012452

There is no capital city for Earth, since it is divided between nations. IF there was a capital city for Earth, there would be 3. New York, Tokyo and London, due to them 3 cities having been classified as an alpha+ world city, and being major economic hubs. or somewhere in Present Day U.S.A, since it is Earths only 'Superpower' and will probably be in the 2100's as the United North American States.
