Underground Martian Civilization? Yay or Nay?

Alien hunters have reported that a NASA photo reveals evidence of an underground city on Mars. Is this for real? How does one de-bunk or verify? Well, let’s take a look together.  NASA explains that the image below is a small mesa surrounded by sand dunes on what is called the Noctis Labyrinthyus at the western edge of the Valles Marineris on Mars.

The gringa thinks the description by NASA of these formations being created by sedimentary deposits is probably accurate, rather than believe it is the ancient remains of an underground civilization. Scientists believe that over time the boulders of a Mars of long ago have since been eroded by the winds that blast across the surface of Mars, resulting in the formation of the mesa. These winds have also blown out sand that once filled the cratered mesa, revealing it as we see it now.

Now, Mars is a very windy place. There are not natural wind breaks like treelines or mountain ranges. The surface of Mars is incredibly vulnerable to the slightest atmospheric disturbance. Wind speeds have been recorded at rates of 60 mph. Although that is about half the velocity of Earth’s hurricane force winds, remember that the atmosphere on Mars is about 1% the density of Earth’s. That means particles remain suspended longer and pack a greater whollop when they hit something.

Now, the UFO hunters who claim that this cratered mesa is a superstructure, particularly a ventilation shaft of an ancient underground Martian city, the gringa has a few questions about why ancient Martians would need to live underground. You see, although Mars is a wasteland today, it hasn’t always been so. Scientists theorize that once upon a time Mars was much like Earth, lush, green and having vast surface water resources.

Geological studies by NASA reveal trace minerals and a chemistry that indicates a very Earth-like Martian past. The Curiosity rover has detected chemicals that point to an ancient oxygen rich atmosphere on Mars. Ancient lake beds exist. Groundwater is thought to have once filled the Gale Crater.

Before Mars lost its protective magnetic field, the planet would have also enjoyed a greenhouse effect. It would have been warmer. The warming would have been the result of multiple meteor impacts kicking up dust and debris into the atmosphere where it became trapped and acted as an insulator. Although this is only a theory requiring much more geological research, it is consistent with computerized modeling of an ancient Mars that has evolved into the Mars we see today. But the warm, green, wet Mars of billions of years ago disappeared once Mars’ magnetic field disappeared.

Thus the flaw in the claim of UFOlogists that the cratered mesa is a ventilation shaft from an ancient Martian underground civilization. You see, these same UFOlogists peddle  this ancient Martian civilization scenario as a means to support their belief that humans are the ancestors of Martians, who seeded a colony on Earth when they recognized that their planet was dying.

But the problem with this scenario, pointing to an underground Martian civilization millions or billions of years ago, is that at that point in history a humanoid race could have survived on the surface of Mars. There would have been no need to go underground. And if they were invested in a survival escape plan to Earth, surely they wouldn’t have diverted their money, efforts and resources away from their cosmic survival travel project. It would have been a waste to develop an advanced society underground that they knew was ultimately doomed.

So, the gringa tells the dear reader to practice logic, do your research and don’t get duped into believing the fantastic. But enjoy the fantastic for what it is, a pleasurable escape into fantasy for the sheer entertainment value.
