In Battlestar Galatica there is just God, and he can reach back in time several billion years and create another Earth on demand when Kara plugs in the coordinates to the BSG jump drive for the last time.
I'm not sure if you're being rhetorical, or what, but just for the record, this didn't happen. Earth—the real Earth—was established as existing at the climax of season three in "Crossroads, Part 2," in the zoom shot on the galaxy.
Also, there is a matter of interpretation, as it is an open question exactly who or what God is in nuBSG. It is true, and I will agree on this point, that God is a mystery. That much, and more, is certainly in common with what people in real life consider God to be. However, at the series climax in "Daybreak, Part 2," words are attributed to the being known as God by Head Baltar, that God doesn't like the name God, which would seem to be at odds with the Judeo-Christian God.
