Is it possible for creatures with intelligence more advanced than humans to evolve naturally in the universe?

So let's say that the aliens have fewer restrictions on brain size, and have more efficient brain wetware, and are subject to sexual selection for intelligence, then they will likely be much more intelligent than us.

Then we can wonder about the evolutionary selection pressure for intelligence.

Social groups, and theory of mind. You needed to keep tabs on everyone in the group and understand their drives. Being able to negotiate. It takes intelligence to succeed with this.

Why are Republicans so afraid of a strong leader like Vice President Kamala Harris? Are they worried if she becomes President she will make them look stupid?

Sexual selection. Intelligence is sexy. If you could tell a better story, make a better plan, make a better tool or weapon, you would be popular and get laid.

They may also not have the same limitations for the size of a birth canal. If they are similar to marsupials, the baby would be born very small and then develop in the pouch, without head restrictions of the birth canal.

And since the universe is so enormously big, it would be strange if we were the most intelligent creatures. Though, we will probably never find out.

Why do most men who date ugly women brag like it's some big accomplishment, when any guy can pull an ugly woman?

Aliens may have more efficient brains than humans, like birds, or even more efficient than any animal on Earth.

Human intelligence is limited by how the brain works, and how big the head on a baby can be.

Possibly, for us, it was a combination of different things after it reached a certain level:

How do people move on so quickly? I’m still sprung over someone I was dating and he found someone else so fast. I feel hurt because I’m still head over heels over him while he’s out enjoying his life with someone new

Right here on Earth, birds have at least twice as dense brains as humans. That means that they cram at least twice the computing capacity in the same space as primates. If we had bird brains we might have been much more intelligent.
