Also, you live on one planet next to one star among a galaxy filled with upwards of 300,000,000,000 stars, in a universe with 300,000,000,000 galaxies, each galaxy in turn filled with hundreds of millions to hundreds of billions of stars. You share fifty percent of your DNA with a banana. You are more closely related to chimpanzees than mice are to rats. You are directly related to every single living organism on this planet. You are, in fact, related to every non-living entity as well (including the device you’re using to read this) because all of our elements were forged together inside the hearts of dying stars. Everything you see in the universe has evolved from a point of infinite mass and density, to quark-gluon plasma, to hydrogen atoms, to complex elements, to you! But all of that stuff we can interact with only makes up 5% of the matter in the universe. The rest is dark matter and dark energy, which we can’t see, hear, touch, smell, or taste. You wouldn’t be here today if you didn’t have an unbroken lineage of survival tracing back to the beginning of life on this planet. That means not a single one of your direct ancestors, stretching back over three thousand million years, has ever died before successfully reproducing—this occurring on a planet where over 99% of all species that have existed are currently extinct. Survival is the exception, extinction the rule. Yet here you are. You are also constantly replacing the cells in your body, so much so that in 7-10 years not a single cell in your body will be the same as today. You are, down to every last atom, a different person than you were when you were born. Yet your brain still manages to be ‘you’, day after day, year after year. All the solid material around you is not only 99.9999999999999999% empty space on the quantum level, it’s also in a constant state of dynamic agitation. All of your atoms are dancing, jiggling waves and particles, existing not as individual entities, but only as probabilities. Put enough of them together, though, and we get the world as we know it.
