Ask an evolutionary biologist for the details, but the likelihood of another species evolving with traits like ours is incredibly unlikely.
It took a specific combination of gravity, temperature and other environmental factors to produced monkeys that started walking upright and developed tools.
Also remember that our species is relatively new to the planet. The universe is old, very, very old, billions of years old. Our planet's lifespan is a fraction of that.
So we'd need a planet that's been around as long as ours, with the same distance from the sun, with the same density, with the same temperate zones, with the same combination of predators and prey to allow a humanoid species to dominate.
