I'm not the big expert on this. But I do recall that Glen Larson had created a preliminary version of Galactica before Star Wars. At the time I think he called it Adam's Ark. Or something like that.
Now I do think there are alot of similarities to Star Wars, and thought of by ABC as a way to cash in on the Star Wars fad, but I consider that part of the history of the creation of the show. The show itself was pretty wonderful. Especially considering the rather insane rush ABC demanded to produce the episodes. (to catch as much of the Star Wars fad as possible). And personally, I myself like the characters more in the orignal show than Star Wars. But that's just a personal preference.
I also remember Universal and George Lucas reaching an agreement, prior I think to the airing of the show. Certain changes were demanded and were made such as no laser beams shooting out of black laser guns. Why I don't know, Star Trek had that before Star Wars. But even after Battlestar met Lucas's condition, he still sued, and eventually lost.
but here wee are today.
