Right, I see where you got the numbers from now. I am sorry for misunderstanding you.
You're still wrong, unfortunately. Life isn't a lottery where the winners are chosen randomly. Your existence owes itself to the existence of your parents, and they in turn owe their existence to the existence of their parents, und so weiter.
The notion of potential selves is as wrong and meaningless as the notions of potential rocks or potential blades of grass or potential carrot cakes; the fact that my local supermarket sells all the ingredients to make several thousand carrot cakes at any one time has no bearing at all on the chance of the carrot cake I intend to make tomorrow existing, or the chance of the one I made last week existing when I made it.
Yeah, I tried this line of reasoning before with Jabba.
Jabba must have two parents. Each of those must have had two parents, so now Jabba must have 4 ancestors. And the progression continues.
So let us take a generation as a generous forty years. 2,000 years ago that means there were 1,125,899,906,842,624 heartily making the beast with two backs to produce Jabba. That is more people than have ever existed. And it doesn't include the intervening generations, only those from 2,000 years ago. And it doesn't include mine or yours or anyone else's, just Jabba's alone.
Since there are now 7,000,000,000 of us, 2,000 years ago there must have been 7,000,000,000 x 1,125,899,906,842,624 = 7,881,299,347,898,368,000,000,000 of us.
That is 1,435,573,651 ancestors per square foot. Just 2,000 years ago. And we have been about for a lot longer than that. I rather think we might have noticed that.
Jabba's response to this was "gee, I never thought of that, let me think about it and come back to you"
Did he ever return to that? Guess.
Bottom line? Jabba is delving into math he does not understand.
