It's a common theory that Mars used to be a good place for life, but no one's quite sure why it's so bad now.
The explanation I remember best was that it cooled too much to support volcanic activity. Earth's volcanic activity helps replenish the atmosphere to a degree if I'm remembering what I think I heard correctly.

It was that or the fact that Mars doesn't have a rock cycle...
(I forget the actual name but, meaning it's craters are permanent are's aren't...
However, there might be life underneath the surface...
(I know I watch the science channel to much...)

Alien life could simply be foreign bacteria because bacteria is living even though it doesn't have self-awareness.
