“The probability of a human brain coming into existence is very low.”
Low? High? The evidence is that it happened.
The probability of historical events is 1:1.
“Astronomically so, even given billions of years which most secular humanists believe in. The odds of the complexities of the human brain coming about by sheer chance are incredibly low.”
Good thing no one’s talking about sheer chance, then.
“However, the odds of over six billion of them coming into existence by random chance is far lower. Abysmally low.”
Huh?
You think every human on Earth is the product of an individual creative process of random chemicals brought together?
No inherited traits, just start from scratch with every egg?
Holy crap that’s stupid.
I mean, really.
“Therefore, for the rational atheist,”
I really don’t think you’re in a position to pass judgment on anyone else’s rationality, not if you think all of the biosphere is the ‘character design’ stage of a role playing game.
“(Is that an oxymoron? True materialists don't actually believe in the mind....)”
No, sweetie, materialists don’t believe in the SOUL. They believe in the mind, it’s just a product of the brain and only the brain.
Really batting 1.000, ain’tcha?
“it is far more likely that only you actually exist, and that everything else is an illusion.”
Yeah, read that Mark Twain story.
It’s possible. However, I really question how you come to ‘more likely.’ I doubt you, I doubt your math, I doubt your definitions….
“That's just so much more probable than that six billion plus brains came into existence randomly. Isn't it?”
Maybe. But you’re comparing apples and the third man in charge of the janitorial staff of the dirigible that makes tourist trips to the moon.
