3421Dave,
- Out of all time, it happens that we both do exist, and that's when we're both doing it.
We are all here now. If we were not, there would be some other group having a similar conversation.
What on earth is special about right now?
Now, you committed to me personally that you would think about and address you ancestor problem. You alone must perforce have 9,223,372,036,854,775,808 ancestors and that is just going back to the alleged time of jebus. Further, all 7 billion of us must also have that many ancestors giving us 64,563,604,257,983,430,656,000,000,000 ancestors around the world. More people than have ever existed in the entire history of humanity, cumulative.
And that is only going back 2,000 years. Go back to the alleged time of Noah and it gets exponentially worse for your argument, reaching 21,778,071,482,940,061,661,655,974,875,633,000,000,000. You have never addressed this, simply brushed it under the carpet. Why might that be?
That's only 4,500 years. Roll it back 200,000 years and it becomes exponentially bigger again. Point is that it will never reach anything remotely approaching infinity, just a very large number and there is a huge flaw in there that you seem unaware of. Can you spot it?
And to confound you, 74,000 years ago, the human population fell as low as 1,000 to 10,000. That severely restricts the number of "potential selves".
Using those facts, your misapplication of Bayes proves that YOU do not exist right now.
