那一男一女从garden of eden 偷了 apple 然后逃走。(就是game里的那粒球)打英文比较快:The staff and the apple can control human mind and that's why people want them so badly, including the one who created animus and abducted Desmond in the first place. Desmond is the descendant of assassins who knew the apple well. So in ac1, Desmond plays as Altair in the animus and then Ezio in ac2, but his true identity is Desmond. Towards the end, the alien or our ancestor talks to desmond through ezio and this is why ezio cant understand her words. There was another highly sophisticated civilization before our civilization and they created us ( adam and eve) and control us using pieces of eden but we mankind rebelled. They eventually extinct and the ancestor is trying to warn us about the end of the world in 2012.
