That's so weird! I haven't been on this wiki in FOREVER (got a little busy and distracted, and a lot of the distraction was due to the Doctor), and I've been OBSESSED with Doctor Who all day because of that new episode! So I randomly decide to come here today, and look at that! A fellow Whovian!

Anyway, I think that little girl at the end of the Day of the Moon (I'm assuming you saw it; if you didn't you might want to stop now. Spoilers!) was Amy and Rory's child that was kidnapped by the Silence some time around 1962 (she looked about 7 in '69) and that the reason for her timelord powers is that she's actually Donna Nobel and that her becoming part timelady in the future somehow affected her past too (I can just imagine them saying "once a timelord, always a timelord"). Donna had her memories of the Doctor erased, but she still has timelord powers from the Doctor's severed hand, she just doesn't know about them. Maybe she is able to remember when she is close to death, just long enough to regenerate into a child and start her life all over again. One of these regenerations could turn her into River Song, who would shoot him the first time she met him out of fear because he would know everything about her and she wouldn't even remember him. That would make her the person in the astronaut suit. River being Donna could also tie back into the season 4 episode when the Ood say that they will sing of the "Doctor Donna," but also that the Doctor's "song" (Get it? "Song"?) was ending soon. And maybe the Ood's songs eventually stopped altogether, leaving only "Silence" (because if you'll notice, the Silence look a little like the Ood, so they might have evolved from them).
