There is no reason to believe that Mars ever had life let alone any kind of civilisation.

Certain individuals have used excessive observational license to fancy that they see things that aren't there when they look at the topography of mars. They see "cities" when the rest of us would see boulders, faces where sober people would see hills and ravines. Upon such fantasy they build an edifice of alien habitation, migration to earth and worse.

No wonder they are not taken seriously by professional scientists. It is shameful that there are people gullible enough to believe them.

Cheers!
 
Mars used to have a thicker atmosphere and there used to be flowing water. So yes, it may have been similar to Earths atmosphere at one time. But also consider that the Earths atmosphere has changed over time too.
 
Some time in the distant past Mars got walloped so badly that most of its atmosphere was lost along with half of the crust of the planet. This also shut down the internal dynamo that generated the magnetic field that protected the Martian atmosphere.

If there was a civilization that was as advanced as ours on the planet at that time, I think they would have had enough lead time to prepare at least a time capsule memorial to themselves, if not extra-Martian colonies.

Since those things are not in evidence, I think there has never been a civilization on Mars that achieved space travel.

If there was life there that got to, say, the level of Europe in the 1930s (a level not capable of space travel, but capable of leaving behind a memorial to themselves), or even to the level of having permanent cities ala China or Mesopotamia circa 4000 BC, then I think we will find evidence of it when we fully explore the planet. I think such a finding is very unlikely.

But, I subscribe to the view that if there is water, then there will eventually be life. And life is very hard to eradicate.

And so, given that there was liquid water on Mars for perhaps two billion years, I think that there is a good chance that life did actually evolve there. And, having evolved, I expect that it persisted. So, I bet that there is primitive life still extant on the red planet - i.e. organisms equivalent/similar to terrestrial bacteria.

I look forward to the science and engineering that will allow us to examine these possibilities ... I really hope we get there with the necessary technology before too long.

I also think there is a pretty good chance that primitive forms of life will be found on Europa and Enceladus.

Nope. Even the atmosphere at Everest is far thicker than that of Mars.

Mars was never really habitable save for the first few hundred million years of its existence. The problem was that Mars didn't have enough gravity to sustain a molten core which in turn meant a low magnetic field once the core cooled. After that is was subjected to the solar winds which continually, to this day, degrade the atmosphere blowing it off into the cosmos.

Being that all of this happened so soon after the formation of the planet, there would not have been sufficient time to sustain any kind of civilization.

Another point to bring up would be that the planet has no continental drift occurring. By that, it would prevent the recycling of materials within the planet, meaning anything on the surface would be extremely finite. If there's one thing an advanced civilization needs, it's resources.
