I suspect the hypothesis life on Earth actually started on Mars and traveled here through microbes carried by meteorites ejected in impacts will be eventually confirmed. Explains why life appeared almost immediately after the Earth formed. Mars cooled and had liquid water several hundred million years before Earth, so life had more time to start there.
