If there is no meaning, how can one find it?
I mean that there is no meaning to all life, we are a natural phenomena no different from this universe being born, or the stars that form, or those that collapse into blackholes
Trying to find out what you, as a human were meant to to on an existential level is simply a fool's errand in my opinion, im not saying this to be nihilistic but humanity as a whole, and especially a singular human is insignificant in the grand scheme of things in the cosmos, so you could say that in its eyes, you dont mean anything
But that shouldn't deter you, you live here, on earth, on a continent, in a country, a city, living your everyday life
Through your experiences you will form a personality, through that personality you will make decisions, and those decisions will affect something to some extent
Seek a greater purpose through that experience, maybe you think that people who have no idea when their next meal will be deserve help, start a charity
Maybe you feel compelled to unlock the mechanics of the world you live in, study hard and become a researcher
Or maybe you want to show the world how you see said world, become an artist
Whatever you choose, or even if you've done all 3, at the end of your life you can look back on the entirety off it, the people you've affected, the lives you've saved or perhaps taken, the impact on history you had, you'll have the answer on what the meaning of your life was
