First off, it's Aang. Secondly, while I don't really see the point of this, I'll humor you. While Ben could do that, it wouldn't have any effect on earth. Aang can bend all four elements at once, while Ben can only use one alien at a time. Though Aang's ultimate ability, spirit-bending, would have no effect on Ben what-so-ever.
