Panspermia

   Life from one planet spreading to another. Possibly a meteorite impact threw a stone with organic matter into space, say from Mars. Hundreds or thousands of years later that rock impacts Earth as a meteor and the organic matter survives and thrives on Earth. This could be how life arose on Earth. It could be possible that life formed only on one planet in the universe, and through meteorite impacts spread to other planets, so that all life in the universe has one origin. See Meteorite ALH84001,0.
