There are still a ton of rule-outs based off of limited assumptions. The idea that we'd need to find water somewhere in order to find life is one. Just because it works on Earth doesn't mean it's how it always works.
I agree need to know which of us are pod or human............We should all eat Arsenic to make sure we aren't aliens. Those that live will promptly be killed.
