Science fiction aside, we know that there were not ancient civilizations or a population of little green people on Mars. So, what sort of things do we need to look for to know whether there was ever life on Mars? Fortunately, a robust Mars exploration program, including orbiters, landers, and rovers, has enabled detailed mapping of the planet and constrained important information about the environment.
We now know that there were times in the ancient past on Mars when conditions were wetter and at least a little warmer than the fairly inhospitable conditions that are present today. And there were once habitable environments that existed on the surface. For example, the Curiosity rover has shown that more than three billion years ago, Gale crater was the location of a lake that held water likely suitable for sustaining life. Armed with information about the conditions and chemical environments on the surface, the Perseverance rover is outfitted with a science payload of instruments finely tuned for extracting information related to any biosignatures that might be present and signal the occurrence of life.
KENS NOTE: NASA MUST BE VERY NIEVE OR STUPID TO THINK WE WOULD NOT FIND THE THINGS ON MARS THAT THEY ARE TRYING TO HIDE. ABOVE ARE A FEW MORE DISCOVERIES OF LIFE ON THE RED PLANET.
