God give us intelligence to "govern" the world. Has this ever happened in the history of evolution?
We caught whales and kill tigers. Who is stronger?
Intelligence on the level of humans? I think you greatly exaggerate how much smarter we are compared to other species. For one thing, given the number of hominid species that existed in the past that have since gone extinct (some, thanks to ancient humans), it's reasonably probable that a few of them had roughly the same, perhaps even a little higher, intellectual potential than humans.
Inevitable question coming from opposing side: "why'd they go extinct if they were so smart?"
Intelligence, while a great trait that is advantageous in most contexts, has a huge cost that can severely impact survival in a negative way: caloric requirements. Prior to the extinction of all species in our genus besides our own, ancient humans had begun to migrate to other regions. Wherever they went, they competed with native hominids for food and other resources, to the point that the other species went extinct. In the case of which member of the genus would win out in the end, it was the most prolific and aggressive that won out more so than the most intelligent.
Furthermore, potential to learn says nothing of the knowledge one actually has. For example, for a great deal of human history, people that lived in China were at the height of knowledge in practically all subjects, while people in Europe were ignorant savages by comparison. Later on, it would be Europe that was the center of scholarly collections and knowledge. The reality is, both populations has always had the same potential to learn, but matters of circumstance made one population more lacking in knowledge than the other, and changes in those circumstances later caused the intellectual shift.
Same idea applies to other intelligent species that existed in the past. Our ancestors could have had better weapons and invasive tactics thanks to matters of circumstance allowing them to develop them sooner than a more intelligent species and win out.
If you think about it, humans are the ultimate invasive species.
