to be almost impossible. However, I think, therefore I am. Think about the tiniest of events that lead to you being who you are. A bee, ten thousand years ago, that caused an ancestor to walk in a slightly different direction and meet a partner who would also become your ancestor. There are billions of stories through time that led to you, from the quantum level to the molecular level, to the cosmos level, evolution, human society, human consciousness - there are so many factors that led to you being you right now that it seems almost impossible.
If I threw a dice a hundred times and wrote down each number. What would be the chances of getting all those numbers in that exact order? Pretty small before it happens. But after the event has happened we know that was the order of the numbers. There was no magic. There was nothing extraordinary. That is the way it happened. Can it happen again? Yes.
