Re: So...where are WE? (Spoilers!!)
IMHO: if this has all happened before, and again, then we have a 2000 year cycle of building intelligence / revolt / war / move to another planet. We're in the future and this has happened a LOT of times. Earth was the original origin, but the origin is always viewed as the last planet we started from.
This is exactly what I feel the reveal will be, possibly topped off with none of our characters being human as in like us, but in fact all one or other generations of Cylons.
You see we are all the same deep down despite our differences... maybe RDM's message?
I believe in a better world, so I love Star Trek. I have to live in this one, so I love Battlestar Galactica.
