How is Clara Alive?

How is Clara alive I think is the ultimate question. I have a theory that she is a teselecta. The Silence ( religion) created her to kill The Doctor. As the teselecta saved the Doctor they messed up time so they had to kill him. They get help from the Silence who already know the Doctor has got away thanks to the blue guy. They make "Clara" to get close to The Doctor and kill him when it matters most. The Silence made a deal with the Daleks to "forget" about the Doctor. Also in A Good Man Goes To War Strax died. The Silence saved him using the machine he tried to save Clara with and he had to pretend that Clara died for his life. Clara being able to live for ever will intrigue the Doctor like other Moffat characters like Sherlock and Tintin they both want to find answers like the Doctor will. Also here is just a little thing, the Doctor deleting data of him self means he is falling in the Silence's trap by stopping the question being asked. Bye.
