Heisenberg's uncertainty principle states that there is a physical limit to measuring a particle's position and speed at the same time. If we observe it's speed, it's position becomes unclear. If we measure its speed, then it's position becomes unclear. You can test this principle by yourself at home (double slit experiment). Consequently, we observe that the world is inherently uncertain and outcomes that we see around us are purely through happenstance.

As a collection of fundamental particles, I exist because you are observing my words through your screen, and you'd have no way to know my existence if you have never seen this thread. Consequently, the timing of your observation matters to me in an existential manner. If you observed me in a different part of my life, I'd be a different person, and in a different location. I call this my persona cloud, cleverly alluding to the electron clouds in atoms.

We make choices that alter our fates all the time. If I never made that tea 10 minutes ago and walked outside, a meteorite could have hit my head and killed me. And yet, these were all probabilities that laid in the uncertain future that I had no way to confirm or deny beforehand. Consequently, it is true that 10 minutes ago I was both alive and dead at the same time. My post is the proof that I am alive right now, to the version of you right now. But this is not a fact set in stone. In another life, in another quantum world, you never knew me and I never knew you, because I was killed by the meteorite. And yet, through Heisenberg's uncertainty principle, we can reason that our world and that world is equally real.

If we rewind the time far back enough, and redo the history in a very specific way, I would be in your position, and you would be in my position. And yet that must have happened, out of all the infinite possibilities, it is true at some branch of the event tree of the universe. Consequently, your observation as an isolated person who is a different person than me is uniquely confined to this particular branch of the events that have transpired throughout the universe. We toiled and lived and learned about the world in our separate ways, but at the end, you are me, and I am you, we are the same, just at the separate branches of all the events, starting from the Big Bang.
