[Invader Zim] How old is Zim? Is he a child, or an adult posing as one?

Tak mentions that she's seeking revenge against Zim for events that happened 50 years ago (during Operation Impending Doom 1, IIRC). Idk if those are earth years or not, but they just say years. And Zim was a full invader rank back then. So I'd say he's an adult by now unless Irkens live for millenia.
