that they were there? if there was a people that lived on mars and that were somehow extingushed leave behind some traces of their being there after say 25000 years or would all traces be gone?
 
it is most likely very unlikely that there was a civalization that lived on mars the reason for this is that it took about 500 million years for life on earth to evolveand for life to be you have to have a number of factors that contribute like water and mars only had water for a very short amount of time so that gave life a very short time to evolve in to more complicated lifeforms so it would be unlikely for life to be there anyway but if by some spectacular feat life was there and built a actual civilization without us knowing the city would most likely be destroyed from the erratic climate of mars like the annual dust storms every summer the constant heat expanding and cold contracting from the extremely hot temperatures in the day and freezing temperatures in the night you would also have to take into consideration what materials they use and the location to sum it all up very unlikely that life could even well survive and after thousands of years there wouldn't be much of anything left of the civilization
 
Absolutely yes! If you like to read science fiction try Ben Bova's "Mars Life." It deals with just the thing you're asking about. In the book ancient cliff dwellings were discovered in recesses among the cliffs of Valles Marineris that were some 60-million years old.
