On the other hand, we haven't dug extremely deep on the surface of Mars, and Mars lost its habitable status a really long time ago, which as a layman I understand means Mars has been battered by a dusty windy climate, that pushes dirt around alot, and solar radiation can get through in a myriad of ways and other not great things for life. So I imagine, if there was evidence for life on Mars, before the habitability went sideways, then it would likely be many feet deeper than we ever dug. I'm not holding my breathe, because the likelihood is pretty small, as all this happened 3.6 billion years ago, but if we did find undisputable evidence of civilization, it would be game changing. I simply hope it isn't Prothean ruins and a map to the nearest Mass Relay, cause what comes next is a bad time.

From my understanding, it's doubtful Mars ever had a civilization. It's plausible it had life but only just so since it only had its habitable status for just about the amount of time it took life to first appear on Earth.

  That would be assuming that it would have followed the same trend as Earth. It’s highly likely you’re right and I acknowledge that, but it’s not an absolutely certainty that it would have taken as much time for life and possibly civilization on other planets as it did here on Earth They could have had a more rapid development cycle for whatever reason. We simply don’t know definitively

    Yea, it could have been more rapid or slower. Perhaps if it cooled down faster at the very start? I'm not sure, but I'd wager that the conditions couldn't have been that different. And it took multicellular organisms a few billion years to show up on Earth. We don't know definitively, but it seems highly probable we won't ever find remnants of complex life there.

      Highly probable isn’t the same as not possible. IMO it’s worth the cost to find out
