Amy doesn't have any parents.... Any memories of major events.
The first crack was at her house....................
SHE'S EVIL I TELLS YA"!!!!!!!!!!!!!!!!

Still hot though

Exactly, Amy lived in the house with one of those cracks for years, whose to say which side she is from originally? We never see family, only friends, and I still think there is some kind of link between the Duck Pond from the first episode and Amy Pond, though I couldn't even begin to guess at what. Amy is the key, I'm certain of it, I'm just not sure how....
Edit: I see Wobble noticed that too....
Just a thought, if the Pandorica is created by Amy's mind, does that make her Pandora, is she the one who re-releases hope back into the world?
