The possibility of life on Mars is a subject of huge interest in astrobiology due to its proximity and similarities to Earth. To date, no proof has been found of past or present life on Mars. Cumulative evidence shows that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms. The existence of habitable conditions does not necessarily indicate the presence of life.
Recently, 3 new underground lakes were detected near the South Pole of Mars.
According to all the gathered data, the surface of Mars is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen.
And it has been theorized that the water on Mars was lost to space (Mars doesn’t have a magnetic field to protect it from solar wind), some of the water reacted with volcanic rocks and then got trapped in minerals, and some of the water is still there today, frozen into the ice caps and in permafrost layers below the ground.
But the discovery of liquid water lakes has put the assumption of all the left water being frozen into ice caps and permafrost layers, to bed.
We have only been looking at it from one position. What if we were to change our point of view? What if we were to start thinking beyond our limits?
The point from where I can see it, after studying, analyzing and understanding the evolution of life on Earth and the ways we have used to build new problems and then deal with them, theoretically, I find it quite possible that once, billions of years ago, Mars might have supported life and probably might have been a home to some civilization.
And seeing the structure of the planet as shown in the collected data and considering all the factors, there is a great possibility that the civilization might have been one of humanoids.
As for the current condition of the planet, it is theoretically possible and widely acceptable to assume that those humanoids might have destroyed the planet in the same way we will destroy Earth one day.
After reaching a certain stage of destruction, they also would have tried every way to save their planet, thus using all of its remaining resources.
As for the magnetic field, Earth’s magnetic field has been found to be weakening too. Once the strength of Earth’s magnetic field reduces to a certain point, we will also be affected by the solar wind, the harmful cosmic radiation and the charged particles emitting from the Sun.
And as for Mars’s magnetic field, it certainly would have dissipated a long time after the end of the civilization on the planet.
As the planet’s atmosphere became thinner and pressure reduced, the planet’s global average temperatures might have started to decrease exponentially, thus leading to freezing of the molten core. With time, that mostly frozen core might have led to the reduction in magnetic field.
And if that is what happened, who is to say that we won’t do the same to Earth?
More than trying to find new planets on which we can establish new colonies, we should rather be working on saving the one we are living on at the moment.
