Jabba,
I know this has been tried before with absolutely no effect on you, but I like the analogy and I will try again:
Imagine you buy a lottery ticket. Before you look, you have a posterior probability of holding a winning ticket of 1/1,000,000. Now you look down, and your ticket is a winner (number, 01, 03, 11, 28, 49). Your probability of winning the lottery is now one! Oddly still, you look down and see 01, 08, 12, 22, 44 on your lottery ticket. This is not the number of the winner; it is a loser. But the posterior probability of obtaining that number is also 1/1,000,000, and your probability of having that number right now is also one.
The same statistics are relevant to you! The probability of your existence, being you are here, is one. Posteriorly, becoming Jabba in particular is very rare (otherwise there might be two), but you are here, with a probability of one! Posteriorly, you could have been someone else (some other number): your sister, or brother, or one of many combinations of sperm and ovum that never happened or made it. Your probability of being someone, anyone, is quite high; you had to be someone- you happened to be Jabba ("winning") See?
