Sure, but which species is sitting here having a conversation about it?

Why does that imply superiority?

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.

They can go on believing that and it would be true.

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.

The apex predators of the Earth who are in control of it using their brains that nothing else can match. They also regularly contemplate this using their morals, imaginations, and reasoning. Definitely far above the rest.

We are not in control of Earth lol.

Eh, for varying definitions of control.

Which species, in your opinion, controls the Earth?

None. Every living thing is at the mercy of nature.

At least six global mass extinctions suggest to me that you're correct. However, life itself did survive global magma flows, asteroid impacts, etc. With that in mind I'd say the species that rules Earth is probably a single celled organism which lives deep underground and feeds on chemical gradients. You could blast the whole planet apart without life changing a whole lot for that little guy and his brethren.

We still here too, in the light, on the surface, surviving the same six global mass extinctions.

Not a valid answer. Pick a species with the most power and control.
