Howling:What exactly did Moffat erase?

There's another thread about Moffat's confirmation that, because of the cracks and the reboot, the highly public invasions of the 21st century never happened.

But exactly which stories got erased?

Most likely the real answer is "whichever ones Moffat needs to get out of the way", and he hasn't sat down and made a list, much less come up with a rationale. But it would still be nice to come up with an in-universe answer. So:

1. Everything after some cutoff. Say, the end of the TV movie; 1 Jan 2000 sounds like an important date (and the 21st century is when everything changes, right?), and it includes all the RTD episodes but none of the classic ones. But this wouldn't take care of The Next Doctor, which the Doctor specifically talked about being erased. Or Terror of the Zygons, which Moffat has called out as the one classic story that can't have been covered up or forgotten. And how does it affect all the future stories, from The Keys of Marinus to Cold Blood (which include every companion death!).

2. A random smattering. A few dozen things were wiped out of earth history, and they just happen to include the handful of public-knowledge 2005-2009 invasions, the Victorian Cyberking, and Nessie in the Thames. Well, isn't that convenient? Pretty hard to swallow, but if Moffat doesn't have a plan, it may turn out to be the only thing consistent with the evidence we get over the years to come.

3. The ones that were "complicated space-time events". We know the cracks like to eat those. And for the most part, the invasions that risked breaking a fixed point in time were also the ones that went public. So this might actually work. And I can almost see RTD coming up with it and suggesting it to Moffat (or to the public).

4. The ones that were incompatible with Amy's worldview. The world was rebooted from Amy's memories, so if Amy believed humanity wasn't in fear of aliens, some things had to vanish from history to make that sensible. The question is, why would Amy believe that?

4a. Subconscious choice. She wanted to live in a world where all the thrilling adventures happened all around the universe, but she had a nice safe home to return to. And the Doctor had already suggested that she could will her parents into existence, and hinted that she could fix Rory's existence problems, so why not try this as well?

4b. Traumatic delusion. She's lying there dying from Auton Rory's shot. The Doctor shows up and says "We'll get you into the Pandorica, take you back to 21st century England, and everything will be OK". That's the last thing she hears before blacking out. Then she's in statis for 2000-odd years, being repaired by the Pandorica. When she wakes up, she believes that 21st century England is safe.

4c. Spacetime shrinkage. There's not just one Amy there--there's also little Amelia, who grew up in a world without stars. Of course that world didn't have aliens blowing up Big Ben every Christmas.

4d. The Silence. In another thread, it's suggested the Silence deliberately blew up the universe so the Doctor would be forced to find some way to reboot it, so they could turn their post-hypnotic suggestion ability into a history-editing ability. While writing themselves into the history of the Earth this way, why not also remove all of the threats that were common knowledge? Even if they weren't worried about the threats themselves, wouldn't they prefer humans who weren't all convinced that the universe was full of hostile aliens trying to enslave them? --99.33.26.0 03:16, May 7, 2011 (UTC)
