Yea they specified it was Earth's moon. It could have been another planets moon but it wasn't.. it was Earth's moon. There is nothing wrong with them specifying that indeed that location is Earth's moon, as there are so many in our solar system alone. And seeing as the game has us travelling to other planets, it is perfectly expectable that they could have you visit the moon of any other planet. Say if they introduce a Mars moon in future dlc. Would they just call that 'moon' or would they need definition? Poor subject for a "your momma" joke. Just sayin. The rest were ok at best. :)
