Yes but you have to remember that Chorus happened way down the line once RoosterTeeth had become serious about their world-building of RvB. Back in The Blood Gulch Chronicles they were just having fun and you can see by the time of Season 5 that they had started to become serious.

Also it's not Earth. A quote from Church/Alpha, 'Hey Doc...hello, Earth to Doc? Wait...well this place to Doc?'
