Whenever I look at 'rover'/'lander' pictures of Mars I get an overwhelming gut feeling that what I'm looking at is the remains of a traumatic destruction that happened VERY RECENTLY.
It doesn't look at all old in geological terms. I might be deceiving myself, but, it looks like something bad happened there in the last few hundred years. OK, convert that into geological time and add a few zeros. I still find it hard to believe the state of the surface of Mars ( the parts we've seen ) is any older than a few hundred thousand years, tops.
I can well imagine that if something smacked a several thousand mile long gash through the crust of this earth and blew all the water and atmosphere out into space, our own planet would look like those pictures of Mars within a hundred years or so.
What does your gut tell you about what we know, so far, about Mars?
