If I were to set all of the universe to a previous state, quantum mechanics states that it is NOT a guarantee the photon will hit your eye. The probability distribution will still be the same, but the observation (the photon hitting your eye) may not be. The photon might hit another particle along the way that it didn't hit the previous time. That is how QM works.
