Why is this page told in the past tense? Did Earth get destroyed? Also, it first showed up in Detective Comics #27? Where did Batman live before that? Does it not count unless Batman actually mentions that he lives on the planet Earth?---a reader68.4.176.112 08:22, September 30, 2012 (UTC)
Detective Comics #27 is the first ever comic book appearance of Batman so that is when Earth first appeared in Batman comics... - Doomlurker (talk) 12:09, September 30, 2012 (UTC)
