Has Earth ever been mentioned??

This kind of stems from one of the other threads, but has any references to Earth ever been made in SW?

Outside of theme park rides, I don't think earth has ever been directly mentioned, no. It has been alluded to, but that's about it.

In SW Tales #19, Han and Chewie crashland on a planet that looks identical to earth, encounter some American Indians, and their remains are eventually discovered by Indiana Jones and Shortround. In the original Thrawn trilogy, Luke is drinking hot chocolate, which he says Lando discovered during one of his voyages off-world. Etc.

I also remember there is Legend theory according to which the first humans were kidnapped from primitive earth and taken to SW galaxy by some species, I think the Rakatans, to use them as slaves
