Here is my question, WHY is this important? I would think that if would be more important to prove our life can exist on other bodies. That would prove life is possible elsewhere.
For example, it would NOT surprise me if we sent tardigrades to the poles of Mars or Pluto and could prove our life could survive on other bodies.
What Bel said. You're confusing two different lines of research. If we want to determine whether or not life had evolved on Mars, we'd want to take precautions that we don't contaminate the field with terrestrial life. If, on the other hand, we want to determine whether or not terrestrial organisms can survive on Mars, then we'd bring some along.
You design your experiments based on what you're trying to find out.
