Life on Earth may have originated from Mars via microorganisms transported by rocks ejected from the Martian surface.

“there were tiny astronauts inside rocks that were chipped off the surface of Mars that arrived to Earth and seeded the earth with life as we know it”

While organic molecules could theoretically be transported by such objects, it is highly unlikely that living organisms would survive the extreme conditions of interstellar space and a planetary impac

“if something could survive for that long on a small object which i think is very unlikely then if it would collide with another object that would probably be quite a devastating collision for both parties involved”
