Well, you have the Earth, right? [He draws a helpful circle in the air.] And then from there you have the other planets: Mars, Venus, and so on. Those can't support life, but if you keep going further out into the universe you can encounter other lifeforms. [Here he moves his hands away from the Earth, like he's hopping planets with his fingers.] And we refer to the beings that inhabit those planets as aliens. My friends and I kinda stumbled onto them when we were abducted into space by a giant robot lion. We've met a lot of different aliens since then though, some nicer than others. The Alteans are definitely the good guys though...and I pilot one of those lions now so that's also pretty cool.

[This might be a lot to tell a girl he just met, but she HAD asked and Hunk was always an honest kind of guy.]

Ah...sorry. That's probably a lot to accept on top of this whole 'Witch brings you to a mysterious Temple to save the universe' thing.
