The problem is how do we know whether or not Mars already has life on it? If we contaminate it with our own microbes, we may mistakenly claim Mars had its own microbes to begin with.
- phkahler 7y agoAt some point we will need to say "who cares". You can't possibly prove the non-existence of life on Mars. So at some point you need to stop looking and get on with things. When is that point? I dont know. My opinion is we should get humans there to have a look and then move forward - assuming they find nothing.
- auiya 7y agoSupposed we are able to absolutely confirm or deny the presence of life on Mars which didn't originate from contamination by us. What problem(s) would that solve? That panspermia is possible? Would that need outweigh the need to discover how to make life survive outside of Earth? Would that not also prove panspermia is possible?
