Would you like someone to take yet another attempt at telling you?
You can't tell Jabba what you don't know.
Go and get yourself a deck of cards, and shuffle it thoroughly. You will now have some specific arrangement of cards. What is the likelihood that the arrangement you have actually exists? It would have to be, a priori, one divided by the number of possible combinations. How many possible combinations of cards are there? The answer is a little over 8x1067; so the probability that you got the arrangement you actually ended up with, is a number so small it has 67 zeroes after the decimal point before its first non-zero digit. By any everyday measure, that's virtually zero. So you've just carried out an operation, the probability of a specific result of which is virtually zero.
No, the probability that you got the arrangement you got is 1. Ask anybody around here. People keep saying that all the time. They think it means something.
That's not the part that's unlikely. What you observe is definitely what you observe. Whether you would have observed what you've observed if X is true is an entirely different question. And your analogy with the deck of cards fails to address that point. You just instructed Jabba to shuffle a deck of cards for no reason, and then you said there is nothing surprising about the shuffled deck of cards.
But the point is, there has to be some final arrangement of the cards. All of the different arrangements have exactly the same probability, so there's nothing particularly surprising about the fact that one of them exists in that particular pack at that particular time, even though the probability is so low.
It would be extremely surprising if a genie materialized and exclaimed "Congratulations! You are a YUGE winner! You had no idea that is your specific winning combination, but it is and always has been. Every time anyone shuffles that combination, I am compelled to grant you a wish! Anything you ask for!
Strange, isn't it. You had no idea. And you even shuffled your own combination."
So that's all there is to it. The probability of the existence of you, a specific person, isn't relevant, because the probability of all the other possible people existing isn't significantly different, and people exist. To think otherwise would be to think that some outside agency is also intervening when you shuffle a deck of cards.
The probability of him, a specific person, isn't relevant to
you. But that doesn't mean it isn't relevant to
him. The probabilistic significance of an observation is dependent on both the specifics of the observation and on the specific perspective of the observer.
Easy example: you may be blissfully unaware that your existence has any probabilistic significance - until it occurs to you to ask how likely it is that you would exist if Vladimir Putin wanted you dead. When you ask that question, you assume a specific perspective. From that perspective, you can conclude with good confidence that Putin probably doesn't seriously want you dead.
