Well I have a presence on the moon, and since we aren't counting population in our figures, then if I build biodomes then they will be filled with people. If by presence you mean the shattered remains of biodomes made out of unobtanium (seriously, arch?) and filled with nobody, then yes, you have a presence there. Though, if I use that same logic I have a presence there, in the remains of some of my missles, so if I build something there my people will magically appear on the moon as well? Lol okay Mr. Cocky.
