So are we going to hear anymore about Earth? I would be really disappointed if, by the end of the show, they don't connect the Earth in the story to Earth in reality. It would make sense if this is the far future, and all they have to say is something about how humans first came from Earth, before going to Kobol.
I would be disappointed if they just ignore this point. Their Earth has a North American continent, why does it have to look so similar to our Earth if this is a Star Wars-like reality, where there is no connection to the real world at all?
