As Davies immediately poses in his article, "Since there are hints that life's history on Earth extends back through the phase of massive cosmic bombardment, it may be that life started on Mars and came here later, perhaps inside rocks ejected from the Red Planet by large impacts" (2001). Davies aptly points out that the movement of integral and unbroken rocks between Mars and Earth is an unquestioned fact, and that various experiments have in fact verified that microbes could have lasted through an odyssey via space if they were in fact cushioned in such material (2001). If, as Davies illuminates, this is in fact the way that life on earth started, through some sort of planetary cross-contamination, then the likelihood of discovering another…
