Earlier quoted context omitted.
Can you clarify? You find the probability that you are human, conditional on already being human, to be too small to accept?
Not quite - I find the hypothesis for "consciousness is everywhere" to be too hard to accept based on the observation that I ended up as human (assuming that humans are somehow "higher" than other being of course). Or stated a bit fancier - the p-value of the null "consciousness is everywhere" is astronomically small, given this observation of me ending up as a human.
The chances that the matter you're made of ended up making you is astronomically small compared to it just being random space dust or something. And yet it happened.
I think it's just selection bias.
