When u consider the very high probablility rates in a preBig Bang phase space you r forgetting one really important factor - time
Without time all probablity becomes moot and defunct as you have nothing to measure any probability against. In infinity 1:2 and 1:1'000'000'000'000 are equally likely (thats not 100% true but I'm tired it's early and I hope u get the general thrust of the point)
