Did they make it to earth on Gallactica? I was never able to watch as much of it as I would have.
Yes. But it required plot holes big enough to drive a Cylon Resurrection Ship through.
Yes, they did, but it was about 150,000 before the beginning of human civilization.
The show ended with a strong suggestion that the one woman ("Eve") from which all humans are believed to be descended was actually the child born to the two BG pilots (one of which was a Cylon).
Twice, three times if you count a earlier episode segment. And then really depends on the interpretation of “Earth”.
When they made it to Earth...
*Earth was populated with hunter-gatherer humans.
*Starbuck turned out to be some type of “Angel” who was secretly guiding their path all along... she just “disappeared” after saying her goodbyes.
*They decided to stay, and they remotely piloted the empty fleet into the Sun.
