The universe is a big place, and we don't really possess the ability to find or see an Earth-like candidate as of yet. Our exoplanet searches are fairly rudimentary. For the solar system, it's very possible that at least two planets have had life and that even some moons may currently have it. Given that, it seems pretty unlikely that there isn't life elsewhere. Given the right conditions, such as Earth, life isn't hard. It showed up almost immediately.
