There is, at present, no evidence that any life forms have arrived on Earth from comets. As well as we can determine, all life on Earth is related to all other terrestrial life; the DNA is all similar enough that we know we're all related.
When we get to the stars, and IF we find other life forms, we may be able to examine the structure of those life forms. IF it turns out that alien life is related to terrestrial life, THEN we may have some evidence to support the hypothesis of "panspermia", which suggests that interstellar space may be teeming with cosmic spores of life.
