With references to Biblical events (fictionally made up in the story) people places and things it is hard to remember who is who. Kara in my opinion is an angel. The references to being the harbinger of death might have meant death to the cylons, or death to the human race as it would fall again. I thought of her being an angel because once settled on the world, Kara says a final goodbye to Admiral Adama and tells Lee she's leaving - her 'job is done' - and will not be coming back. Kara then apparently disappears into thin air and is not seen again. Baltar is obviously god as he is seen years into the future. However he really could be a hybrid which is why he has six in his head. There are so many theories that you could keep reading for years. Just have your own interpretation it's easier that way
