I've been to forty-nine different dimensions and fourteen different planets. I wouldn't expect any of the people I've met to know Earth any better than I know their planets, environment, culture, customs, languages, or food. It doesn't make anyone less than. The issue comes when individuals, like yourself, assume that because someone asks a question they must inherently need it dumbed down for them just in case they're not from around here. Sounds a little like you're projecting, pal.
