That is not strictly true. Even leaving aside the tools argument (a human on a bicycle is vastly more energy efficient over long distances than a wildebeest, for example), our sight and hearing are actually pretty good compared to the rest of the animal kingdom.

For a certain range of tasks, we have the best visual perception of any species. Our eyes themselves are pretty damn good for close-in and medium range work. The pattern recognition processing that input is very, very good due to our big brains. Tasks like being able to detect a tiger moving through the underbrush. Color vision is also very good (at least in daylight) to better pick out ripe fruit and such.

Our directional hearing is better than owls who hunt at night for a living. We can better measure the angle at which a sound source is coming from with around twice the accuracy of an owl. Again due to big brains and very complicated audio processing. The folds in your ears are there for a reason. We aren't as sensitive as other creatures like deer, who can steer their big ears (basically parabolic horns) in a particular direction.

And hand-eye coordination is far above any other species, even other primates.

Don't sell yourself short!
