Kind of like the lost tribe of Israel?
Kind of half way between that and the Book of Mormon. Remember the original series was pretty steeped in the philosophies of Mormonism because the primary writer was a very devout Mormon. To the best of my knowledge Ron Moore (the re-creator of the show) isn't, but he respects the history and foundation of the show so that idea is pretty solidly carried forward. And one of the ways he is carrying it forward is those familiar things, it's something he talked about in interviews back to the earliest days of pre-production, seeding the show with small references to our world (like the kid in the mini-series whose mom was making her favorite dish, chicken pot pie, when the attack started, can't get much more earthbound than chicken pot pie) as a reminder that these aren't aliens, this isn't a dim and distant foreign culture, these are humans with the same roots as us, looking for us.
