Just by the improbable fact biological life has occurred on Earth means statistically speaking the spontaneous ordering of hydrogen, oxygen, nitrogen and carbon must have occurred numerous times on alien worlds throughout the Universe's history. Why? Because of the sheer volume of life supporting planets that actually exists in the known Universe. Some of them have been discovered in recent years.
If life arose here than in all likelihood it is actually a very common event, we just don't have the ability to perceive life's ubiquitous nature because we are limited by our natural faculties, such as sight, smell, intelligence as well as our technologies. These can extend our ability to investigate other worlds with vision never before seen, such as viewing the universe through a gamma ray, radio, or ultraviolet telescopes. Maybe some day we will have the capacity to directly observe organized organic matter on other worlds, but for now we rely on common sense: because life occurred on our planet, against all odds, then in fact it must be quite a resilient enough phenomenon to have occurred on other planets as well.
And when did I say human life exclusively? Why could not an alien life form evolve by process of natural selection and develop higher forms of intelligence, such as developing the ability to alter its own genetic destiny, or alter the physics of its planets and space to further their own evolution?
Humans are not the center of the universe, we are just a highly evolved form of great ape that likes to be clever. Is it not incredible that a form of life reaches out into space and ponders its own existence? Its incredible, actually.
Curiosity might not be the exclusive property of mankind.
