Sure, but which species is sitting here having a conversation about it?
It's like you're saying "We humans are the smartest in the world. Smarter animals are better than other animals, so we're better than all other animals."
A giraffe may just as well believe "We giraffes have the longest necks in the world. Animals with longer necks are better than others, so we're better than all other animals."
"Intelligence" itself is not well defined anyway. It may as well mean thinking like a human.
Yet what have they done with their long necks?
Of course humans define the metric. Who else could?! Lmao.
Let's ask the giraffes what intelligence means... oh wait.
Maybe we can't name it, make it's not a competition or leaderboard, but you can't deny Humans are at the top of something.
