Why the split? Was Kobol the human AND cylon homeworld? That implies those humans and cylons had a war, destroyed the planet, and survivors solved the problem by literally going seperate directions.
Then the 12 human colonies created their own cylons and created the war we saw in BSG.
But what did the cylon centurians do? Create skin jobs that took over, then had the internal cylon civil war we see in last season and destroy Earth? And being more advanced, they merely do it 2000 years before the colonial humans?
So the cycle was repeated on both Kobol AND both sets of colonies?
That is my thinking too..
Well the ‘humans’ on ‘earth’ were Cylon ‘skin jobs’, but the ‘Centurions’ on ‘Earth’ were not related to the ‘Centurions’ on the worlds of Kobol. Go figure!
