NASA seems to think there was !!

This is just proposed, not proven. My point is not that it's impossible that life is or was on Mars, I'm saying that they have no hard proof. This is merely speculation, albeit the evidence POINTS in the direction that there MAY have been life on Mars, but it does not PROVE it. I would LOVE for science to find hard proof.
