the specific sperm cell that made you was one of somewhere between 40 million and 1.2 billion released in a single instance, and that's just your father's side of the equation, your mother was born with all the eggs she'd ever have, about 1 to 2 million, and by the time you were conceived that number had dropped to maybe 300,000, and only one of those became you.
which means before you even existed as a single cell the odds were already something like 1 in 400 quadrillion for that specific meeting, and that's only going back one generation, your parents had the same odds, and their parents, all the way back, every generation a fresh lottery that had to be won exactly right or you specifically don't exist, just someone else does, some almost-you who never got to happen.
And the earth had to be exactly the right distance from the sun, not the 0.1% closer that would have triggered a runaway greenhouse effect like Venus, not the fraction further that tips into permanent ice, but this distance, this specific orbital slot, and our sun had to be the right age and the right size because a star 20% larger burns through its life before complex organisms can evolve.
and Jupiter had to be exactly where it is to act as a gravitational shield catching asteroids that would otherwise sterilize us every few million years, and the moon had to be exactly the size it is to stabilize Earth's axial tilt, because without that our seasons would swing into extremes so violent that sustained life on land probably never gets going at all.and then your body.
right now your immune system is identifying and destroying somewhere between 1,000 and 10,000 cancerous or precancerous cells that formed in you today, just today, your body quietly running this surveillance operation every single day of your life without telling you, and your DNA, which if you uncoiled it would stretch from the Earth to the Sun and back 600 times, copies itself every time a cell divides with an error rate of about 1 mistake per 10 billion base pairs.
which is so precise that human engineers have never built anything that comes close, and it has been doing this since before you were born, all the way down, this obsessive fidelity to keeping you intact. and with all of that, with the whole weight of how impossible this is, what you do with your existence is feel things.
you feel things about music. you feel things about the way certain people say your name. you get a specific feeling in autumn that doesn't have a word in English and you know exactly what that feeling is anyway, you have known it your whole life, it arrives in your chest like a letter with no return address.
the universe assembled itself for 13.8 billion years and built something that gets a feeling in autumn. i don't know what to do with that. i don't think there's anything to do with it except notice it. except be glad the numbers came out wrong enough to make you.
So don't ever get mad when the universe doesn't go your path. Trust it enough to know that it will deliver soon, no matter the odds, no matter the universe, just like it did with you, somehow.
