How do we know that someone living on Mars, could live on Earth?
When they look at life on another planet, I think that the base is Earth, how does it compare to the atmosphere on Earth? How do we know that someone living on Mars, could live on Earth? So just because the atmosphere has little oxygen, does that mean that some other life can live without it?
