Wild idea about Mars ...

  1. Assuming that Mars may have supported life a billion or more years ago, if Mars had some type of mass extinction event or life simply left that planet for Earth, what evidence would exist that large cities once existed on Mars?

    If all life on Earth suddenly disappeared, would a place such a NYC give any clues a billion or more years into the future that it was once a city, or would the ground just be covered in Iron Oxide?
  2. go away
  3. Twinkies would still be around.
