That is strange... you think the old Romans or Eritreans sent probes to Mars?

If I were NASA, I’d have the Rover over there post-haste to make a closer examination.
But it doesn’t look like there is any water up there, so we have to trek on somewhere else!
Croutons!
My personal belief is that they have known there is water and some forms of life on Mars for years.
