Sort of a complicated question, I'll try to ask. How was I born me and not another?

The fact that the mind and body aren't separate is the reason you are you and not someone else.

If you were born to someone else, you wouldn't still be the person you are right now, just born in a different situation. You would be an entirely different person - born to different genetics, exposed to different experiences.

You are you because you were born to human parents in a specific set of circumstances, to a specific set of cell divisions in the womb, to a specific set of experiences, which were equally influenced by your own prior experiences, knowledge, and intellectual capabilities/emotional coping mechanisms.

Yeah I know that the probability of being born as someone else is just the same as being born me. I understand that. The whole point of the question, which everyone in this thread seems to bafflingly be missing, is that I am wondering if there's the same probability of not being born at all, or just being born a different species. Because you know there's a lot of species on this planet, and I think it's awfully chancy that I was born to the human species. I also wonder, since I am made of matter, was there an equal chance of me not becoming anything at all, and just being some random particles, or some water flowing down a river, or part of an astroid that never made it to earth. We all come from the universe, so why am I me and not out there as just another part of the universe.
