I'm still holding out that you can cross-contaminate from planet to planet.

If so, there should be significant evidence on Mars and Venus that would support that theory.

It just breaks my heart that we haven't sent people to Mars yet. It's so silly that we waste so many resources, and we don't do something worthwhile like exploring the solar system. We should have condos on Neptune by now. But I suppose it's just as well we spend billions for illegal immigrant healthcare.
