What I always try to remember when viewing Mars photos is that volcanic activity can create some strange formations, and when coupled with hundreds of
thousands of years of erosion, and/or whatever other processes have taken place on the planet's surface, there are going to be some strange-looking
features.
I also believe that any remnants of a now deceased civilization on Mars would not be on the surface. In the amount of time we are talking about,
everything would have most likely been buried. Especially considering there would have been running water, which is the largest factor in changing the
landscape, and burying artifacts that may have been left behind.
But if there was a population on the planet, it is hard for us to say when this was exactly. Did they die off from the core solidifying, effectively
exposing them to the sun when their magnetic field dissipated, as well as boiling off any available water? I have no clue...For all I know there could
be one-eyed, one-horned, flying purple people-eaters up there on Mars, and that's why I will stay here on Earth.
Really, I no longer have anything relevant to add to this thread, as evidenced by the above sentence.
