Would 150,000 years be long enough for any of the worlds of Kobollian humanity to recover from their own nuclear exchanges?
Not only recover but have a brand new Colony of 12 and set off the events of the original BSG show. Maybe the last of the NuBSg Cylons evolved to become the imperious leader and a new race of Cyons were created (but not by man as depicted in TOS). The fact that that everything is very similar and even the names Adama etc could be 'gods' little inside joke.
And Tom Zarek could be the (ilegitimate) ancestor on Lorne Greene and Apollo (Hatch).
I still think it's funny that "Daybreak" validated Galactica 1980, even if unintentionally.
