^But, as BSG has taught us, sometimes the miraculous happens and we get a bizarre set of coincidences that seem almost divine. God has a plan for everything and He made the system, as is, so that it was a suitable place for humanity to settle on post-Kobol.
I am only half joking because the speculation that the system is stable and viable for humans, even in its somewhat weird configuration, is due to God willing it to be so is a completely valid argument in context of the BSG-verse.
*edit* Damn it! Skywalker
said it more straightforward than me. I concur. God did it
