Could be. Can you find this video?
All I know is...
1. The closer they get to Earth the older things get. (Kobol 2,000 - Temple of five 3000 - artifact 4000) Could be suggesting something here.
2. The constellations in the tomb of Athena match the constellations on the planet they landed on but not our Constellations they were close but not exact. (Sloppiness? could be or could not)
3. The episode "The road less traveled" featured the constellations perfectly in the background throughout the entire episode. Suggesting they were in close proximity to the Solar System and the big gas giant has to be Jupiter. But once they found the basestar they went back to Galatica to carry on wherever they go.
4. RDM said “We will get to a place that we will call Earth before the end of the season.”
Here is some more of what I'm talking about. I have my doubts that this is Earth
