I've read articles whereby some scientists strongly speculate that "life" may have originated on mars and somehow (asteroid?) made it to earth. It is a plausible "concept" (not quite a theory) and if that were the case, what might that do to the whole Creationist "argument?"
In other words, we don't know everything and religion tries to fill in what we don't know. But, that would be a challenge for Creationists.
