The Victory Of The Daleksreveals that Amy has never seen nor heard of the Daleks before.

With this thread left dangled, its then largely ignored.

When the universe is rebooted inThe Big Bang, we never discover if Amy now remembers these events.

I could even throw in some other stuff.

The things that I could change just by thinking.

The Doctor casually mentions that the world could be reset to remove racism and people who talk in cinemas.

(Were pretty sure that Den of Geek readers would be on board with these tweaks.)

Whos to say that the planets knowledge of other recent alien invasions hasnt also been erased?
