Panspermia (from Ancient Greek πᾶν (pan) 'all' and σπέρμα (sperma) 'seed') is the hypothesis that life exists throughout the universe, distributed by space dust, meteoroids, asteroids, comets, and planetoids, as well as by spacecraft carrying unintended contamination by microorganisms, known as directed panspermia. The theory argues that life did not originate on Earth, but instead evolved somewhere else and seeded life as we know it.

Well, we could not plausibly rule it out. Unlikely but not impossible. Funny thought, could an RNA world have developed on a comet, with a freeze/thaw cycle relative to its proximity to the sun... :D
