Re: So...where are WE? (Spoilers!!)
So far (and this could change if there are new revelations), the show's mythology contradicts well supported observational evidence that life on Earth evolved right here. Until that changes, I consider the question "How do WE fit in?" to make as much sense with regard to BSG as it does to Lord of the Rings.
I disagree - the civilisation that the final five came from is not supposed to be ours.
If you assume the Earth is our Earth, then they either come long before or long after us IMHO.
I believe in a better world, so I love Star Trek. I have to live in this one, so I love Battlestar Galactica.
