On earth that very much looked like Sydney Australia. You can imagine the opera house across the bay.

Question: Anders and Starbuck got tatoos instead of wedding rings. So, where did the wedding ring retrieved from the body with the dog tags come from?

I think everyone is right in that humans were the original aggressors and nuked the cylon earth. The cycle has been continuous, as stated "All that has come to pass and will happen again".

Taken into account that the prequel series Caprica is on order. Here is my take. After the Cylons were created to house human consciousness. A group of monolithic religious humans decided to achieve eternal life through downloading of their consciousness to the cylons. However, other humans who believe they were abominations forced them to leave the original planet "True earth" - Perhaps Caprica. They form the thirteenth colony and settled on the "earth" before they were attacked. There were more than 12 models. However, only 12 survived the attack through the download process.

The hybrids that drives the cylon battleships are the true survivors in flesh form from "earth". The nuke also destroyed their ability to procreate. Hence, the experiments in Adama's flashbacks to cylons on experimenting on humans.

As a monolithic faith, they also secretly did not want to destroy the other "human species" unless forced to. So they setup a fail-safe - Starbuck. Starbuck's order is to destroy the other "species" if one ever totally wipes out the other.

Therefore, human and cylon's fate is interwined in this eternal tangle. Balance has shifted from one to the other from time to time. However, if one ever truly succeeds in wiping out the other. Starbuck's true nature will be revealed and end both lines.

Perhaps at the end of the series. Human and cylons will both be destroyed. The survivor will be the hybrid human/cylon babies. Who do not fit into this paradigm. The human/cylon hybrids are the modern man.

It's a mindtrip but great job to the writers on this show.

Maybe something we didn't see in this episode is the key to it all. Somebody had posted wondering what city ruins they were exploring, but I wonder if this is Earth (our Earth) at all. What we didn't see when the fleet approached the planet were any recognizable continents. Could it be that the Earth they were searching for is an ancient planet named Earth, and rather than this whole story taking place in the distant future, it all takes place in the distant past...before humans (or Cylons) were on our planet and that their next destination, a living planet, will be the planet they will colonize, turning their back on technology, and populate, becoming our Earth? Anybody else thinking this?

Maybe it is possible some kind of time travel takes place during last jump to Earth or something. Kara may have found herself and not a clone. When she crash landed on Earth, she brought upon the mass destruction by accidentally signaling a war or something.

I'm glad someone finally mentioned that starbuck could've landed on Earth 2000 years ago. I could take it a little too far and say that her unexpected arrival back then might've caused the disaster that nuked the place.

Anyway i don't they can cheat and say this isn't the REAL Earth, like there's an earth 2 or something. Anymore than they can say Ellen isn't REALLY the final cylon. That would really be cheap. They've got enough on their plate. They have to explain Starbuck, Earth being full of Cylons (that probably thought they were human), how the final five were reborn, what Ellen's role was in all this AND the humans still have to find Happy Ending Earth - i'd be on the same rock but they'd have to time travel (which would be lame) . but however those cylons travelled 2000 years into the future may be the means by which the humans travel to the next cycle, 2000 years from where we are now in the show, then they'd be on a populated earth. I mean the line between Cylon and Human just got paper thin. Maybe the humans can all die and be reborn.

I think it's pretty funny that people expect this story to hang together over all the seasons and episodes. Lots of interesting tidbits have been revealed recently through interview with writers and producers.

1) The Cylons had a plan...this was in the opening credits for several seasons, yet it's become pretty apparent that the writers had no plan to weave together all the seasons. The final 5 weren't conceived as an idea until season 3. The 5th Cylon wasn't determined until season 4.

2) The baby Hera and prophecies meant something. They've forgotten these storylines. Don't expect to have them wrapped up.

3) Cylon/Human interbreeding. On again, off again, no explanation provided.

4) Starbuck, ummm the only thing I had left to cling to is a return to the City of Lights. She has to be something different than human or Cylon to have her storyline make any sense.

I'm trying not to extrapolate from what we've seen. I'm going to accept that a bunch of storylines will not get wrapped up. I'm interested in the final destination but I don't expect a masterpiece of story telling simply because they have been making this up as they went along. There was no master plan spanning all the episodes and seasons.

It seems very much like "A Canticle For Leibowitz".. 2000 years after rebuilding their world, they burn it again. FIAT LUX!

I think the rest of the season is going to be pretty incredible.

I can't believe no one's mentioned the plot point of Starbuck having one of her ovaries stolen in "The Farm" (Season 2). The Cylons have the tech to clone new bodies for themselves and had a farm where they were using human women for unknown purposes. Given Leoben's obession with Starbuck and her "destiny" how do we know that the Cylons didn't just clone her?

telegraphed quote from episode "when I knew you, you had hair" ie final 5 cylon's can age

NOW think about a previous episode where Ellen and a Six are shown morphing back and forwards. telegraphed, again

ie Ellen NOT final cylon model, it's 'another' fake out

Ellen is just an older SIX
