As in, there is a 1 in a 1,000,000,000,000,000,000,000,000,000.... chance that it has turned out eactly the way it has.
Assuming the that the universe is infintely large, which it must be, considering outer space must be endless, then we must assume that that 1 in a Ga-Jillion chance that our world took to occur is being reproduced somewhere else.
There is, in other words, another clone of me somewhere, due to random chance.
There is, in other words, a person that has done everything I have done, but in a world where McCain beat Obama, where George Bush didn't go to war, even where I decided to wear a green shirt instead of a white shirt, all due to possibilities in a infinitely large amount of occurances.
