>>13857308idek where to start, like there are so many ways to think about this. lets consider earth right now, look at how many forms of art we have created over time and look at art in its current form. Most people find most arts to be conceptually complete; everything already been done, and thats just here on earth in a span of 10k years. And thats speaking in terms of visual art. Music for instance is even more limited of an artform and is already susceptible to accidental repetition in a human lifespan.
So now if we start to think about the universe then we have to consider how many worlds there are with intelligent life on them producing art currently. And then we can think about how the universe is much older than earth, and potentially an infinite amount of art already exists right now. All of this is without considering alternate universes/before or after the big bang.
As long as this universe is infinite, and as long as time goes on, its unavoidable for a lot of things considered to be art to be reproduced incidentally across worlds and species and times. I dont think every world will see art and science the same way, especially for example, and intelligent underwater species that manage to form society.
so yeah its a retarded assumption, you didn't try to think out your philosophy at all before outwardly externalizing it and defending it. try thinking more
