Whose name, of course, would be Rim Tin Tin. 
This puts me in mind of an old Star Trek short story, “Visit To A Weird Planet Revisited”. The actors beamed and all got dizzy, then the dizzyness cleared and the lights above the set were gone, and indeed they were on the set of the Enterprise.
What if Adama et al gets back to Earth only to find out he’s not real at all ?

Flying skateboards.
They find Earth. Full stop. If they show us what happens once they get to Earth, they’re going to piss somebody off, or ruin somebody’s vision of it. So I don’t think they’re going to do that. The last shot of Battlestar Galactica, I think, will be something like the fleet jumping into orbit over a planet with recognizable continents. Like the end of season three, only less trippy. And then the rest of it is up to the viewer to decide.
No, it did not, dammit! There were never any such things as flying motorcycles, got it? The humans never went into the past to help the Nazis win WW2. Never happened. Put such evil thoughts out of your mind entirely.
But it’ll be long in the future, anyway (and I agree with VampyChk). “All Along the Watchtower” had to make it out into the void long before for the 5 to have it programmed into them, and that goes back to the dawn of the humans’ polytheism itself. But that opens the plot hole of how the Dumb Little Toasters could have invented the meatbag models themselves, much less in just a few decades - perhaps the meatbags were created by the Original Wayouts instead, based on their understanding of Hendrix’s performance of a Dylan tune from old Earth?
Whatever. Just look for episodes titled things like “Not One of Them Along the Line”, “Life is But a Joke”, “You and I, We’ve Been Through That”, “All the Women Came and Went”, etc. And then I think we can put this series to bed.
Electric Cylonland.
*Star fleet to scout ship, please give your position. Over
I am in orbit around the third planet from the star called the sun. Over
You mean its the earth? Over.
Positive. It is know to have some form of intelligent species. over
I think we should take a look.
Strange beautiful grass of green
With your majestic silken seas
Your mysterious mountains
I wish to see closer
May I land my kinky machine*
–Jimi Hendrix, “3rd Stone From The Sun”
I’ll say here that while I agree your point makes sense, I think the guys who make this won’t be afraid of that. I mean, they had the whole thing about skipping a year in New Caprica that pissed everyone off. I don’t think they’re afraid to do things like that. I just hope that they find earth and continue the story somehow. There must be a way.
I quit watching Andromeda, but it seems to have continued after Dylan restored the Commonwealth or whatever his government had been.
That rendition of All Along the Watchtower was composed specifically for BSG, and I saw an article where one of the producers (Ron Moore or the other guy) said that it wasn’t intended to be a transmission received from Earth.
So we are back to “Bob Dylan is a Lord of Kobol.”
Hopefully, the entire fleet will fly into the mouth of a small dog.
What will happen when BSG gets to Earth?
I see a few possibilities;
1; “Computer, End Program”
2; The planet is populated by management consultants, security guards, and telephone sanitizers, and is actually named “Fintlewoodlewix”
3; Grace Park steps out of the shower (starkers, of course ) and goes to Tamoah Pinkett, describing the “strange dream” she had…
4; “Boxey” wakes up from a fever-induced dream
5; the Galactica jumps into geosynchronous orbit, only to find a Peacekeeper Command Carrier and Scarran Dreadnought slugging it out outside Pluto, and Earth already familiar with aliens, after all, a Nebari, a Luxan, a Sebecean, an Interon, a Hynerian, and a Traskan have beaten them there in their Biomechanoid ship with it’s symbiotic Pilot, guided there by a Human with an obsession with Wormholes and a penchant for obscure pop-culture references
6; the Galactica is greeted by the staff of Stargate Command
7; Earth is fighting off yet another attempted incursion by the Borg…
8; the entire population of Earth has been devoured by Rabid Daggits (Band Name!)
We get the definitive answer to the question that has plagued great minds for the centuries.
Enterprise vs Battlestar.
Speaking as a guy who watches BSG only fitfully, I’d disagree with the notion that the Galactica showing up over Earth 2007 would be uninteresting.
I think it could be fascinating. Think about it differently, not as a fan of BSG, but as if it happened today.
Suppose tomorrow a gigantic starship suddenly appears over Earth. After a few days of amazement, a ship comes down and out step… human beings. They speak a weird-ass language, but within a few days and with the help of some linguists, we can talk to each other, and the boss man says “Hi, I’m Adama. We sure are glad to be here; this is the paradise we’ve been seeking for years. Regrettably, we’re being pursued by a race of genocidal artificial people and we don’t think they’re going to like you much more than they like us. Christ Jesus, I could use a beer. Do you have Moosehead?” Let me ask you this… what would YOU do? What would you your government to do?
How would Earth react? I think it’s a fascinating idea. Would the world unite in defiance against the Cylons? We may be a bit behind technologically but there’s 6.5 billion of us with lots of resources and, after all, it’d take no time at all to copy and build on the neat stuff Galactica brings. How would this affect international relations? What implications lay in two human populations possibly carrying different infectious diseases? Would we quickly accept the Galactica refugees, or treat them as pariahs? Could Earth strike a deal with the Cylons? Would some parts of Earth see a commonality in the Cylons’ religious fervour? Would Earth’s nuclear arsenal come into play? How does this affect the political organization of our planet?
Me likey.
Well, there’d be no more SDMB because we’d have to un-network everything to prevent cylon infection.
Alternatively, the Galactica could reach earth in the year 3000, Futurama-style (Wonder how Bender would react to the Cylons?)
or even more bizzarely, the Galactica sends down an “Away Team” in a Raptor, that just happens to land at a convention… a BSG convention…the Away team exits the Raptor, to find Edward James Olmos, Grace Park, Tricia Heffler, Mary McDonald, James Callis, Michael Hogan, and the rest of the Galactica cast signing autographs and shaking hands, answering questions about the show…
And then they’ll leave the Earth-That-Was, looking for the solar system where humanity moved to - never realizing that their search is hopless because Firefly got cancelled after only fourteen episodes.
It would be the other way around. Two words: Badger Badger
