Are you the best basketball/baseball/hockey/$SPORTS_BALL player on the planet? If so, cool- can I get your autograph?

If not, why even play basketball/baseball/hockey/$SPORTS_BALL? Do you play basketball/baseball/hockey/$SPORTS_BALL not because you’re the best, but because it’s theoretically possible that every single basketball/baseball/hockey/$SPORTS_BALL player better than you might all simultaneously might die, leaving you as the best on the planet? You solely enjoy activities because it’s technically but not practically possible that you would be the best ever, or “make meaningful contributions” to the sport? Or do you play just because the experience of playing is fun?

If someone told you that rock-climbing is fun, would you decide you’re never going to do it because someone else already did? Or would it make you more likely to try it, because you want to know what that experience is like first-hand? You’re ascribing nihilistic motivations to humanity that even you don’t really believe in.
