It takes an extremely lucky set of circumstances to create life as we know it. The odds of a given planet containing life (as we know it) are in all probability, extremely close to 0. Of course, since there exists a virtually uncountable number of planets in our solar system, the odds of there being many other planets containing life suddenly becomes extremely high.
But, the odds of a planet near us containing life, even those planets in neighboring solar systems, is extremely low. Hell, the next nearest solar system to our own is 4.3 lightyears away.
The fastest speed ever obtained by a manned spacecraft was about 24,790 miles per hour. Or, 0.0037% the speed of light.
So, just to travel to our closest solar system, at our current fastest rate of travel, it would take over 100,000 years.
The odds of life existing elsewhere in the Universe? Excellent.
The odds we'll ever see it? About as close to 0% as you can get.
