Wow is that logic messed up.
Exactly right. Trying to determine probability afer the fact is ridiculous and "messed up." So why did you try to do it? That's what I dont understand. Apparently, you knew your argument was based on a ridiculous premise - obviously, because you recognized the ridiculousness of the same argument turned against you - so why did you offer it in the first place?
The odds that the sperm containing half of MY specific genetic material are 1 in 40 million.
No, it's not.
Meiosis includes "crossover", where elements from complimentary chromosomes are exchanged. That means there's considerable variation among sperm in terms of exactly which genes they have and don't have. The sperm that fertilized your zygote wasn't one of 20 million exact copies. It may very well have had an entirely unique mix of genes.
If the odds of simply getting pregnant were 1 in 40 million
Obviously, they're not. Where did I say that they were? Please, don't put words in my mouth - especially not such stupid ones, ok?
We are talking about the odds of life simply forming at all, not the odds of it having blonde hair, blue eyes, and a devastatingly handsome appearance!
If you didn't have the unique mix of genes that you possess, you wouldn't be you. Since the odds of you possessing that unique mix are so low - one in millions - are we supposed to conclude that you aren't yourself?
Or are we just supposed to conclude - as you so rightly did - that trying to argue from probability after the fact is an exercise in tomfoolery?
