I would definitely say no, except the Pyramids, Stonehedge and Easter Island give me pause and time to think. What I do think is if these advance planets did exists they have died possibly just like we may from nuclear waste. Unless we can come up with a way to successfully freeze human life and later reanimate it we will never find out. Luke and Leia are at least 200 tera miles away from us.
