That wasn't the question

It's important to remember that the scientific principle is that a theory
proposed needs experimental data to back it up. Right now we have no direct
observations on the planet. We've had 2 scientific platform landings, but
neither were equipped to look for microbes. All the evidence so far is
in-direct. We're not even sure that the "riverbeds" actually had water in
them at any time. As we get closer to the actual hands on phase of Mars
exploration we will get better and better data.
