BSG

so season 4.5 started today with "Sometimes a Great Nation", overall a very bleak episode, as I figure the remaining 9 will be. It seems to reveal that everyone on earth was a cylon and they were wiped out, which somewhat gells with my theory of cylon scouts leaving earth and deciding to forget they are machines, although it seems like it was perhaps cylon scientists who were selected for some experimental project of resurection. The question becomes did the cyclons wipe themselves out, or did humans intervene? I think humans have been gone for a long time, the cylon children are doomed to a neverending loop of self-destruction and rebirth.
