Using a HUGE stretch of the imagination/two leaps forward.
You'll need to have seen the news/Mars Rover reports for this and a bit of imagination.....
From what I gather there used to be a similar environment to earth on mars but the electrical polar field reversed etc which fracked the sky and killed/decimated everything completely.
I think man lived on Mars, had a massive war and someone pressed the nuclear button that decimated the atmosphere (similar to the sky in the film the Matrix). A small band of men and woman managed to escape in a pod that landed on earth (shades of Superman).
