The likelihood of being human
Sounds interesting and to concern things I know very little about. Could you expand on this point?
As a panpsychist, I believe that existence comprises "streams of consciousness". For instance, my nervous system is one stream, and so is yours. On the other end of the spectrum, a lone atom would be a stream as well, albeit with vastly simpler experiential complexity.
I exist as a human because my stream of consciousness was elevated from commonplace matter into sapience (I became a fetus and then a baby and then a man). For a given stream, this is an extraordinarily unlikely event, given the low percentage of intelligent matter in our universe.
I can either believe I'm super duper lucky, or I can come up with a theory that renders my humanity ordinary, unprivileged, or otherwise expected. To do this, I'm basically invoking the multiverse, and saying that each stream of consciousness subjectively perceives the timeline in which they reach some highest state of being, hence why I find myself as a human despite their rarity.
Trying to define the highest state of being is a whole other can of worms. I can give you my thoughts if you want.
