ars is becoming more of a hot topic when it comes to ancient history and what goes back to even before life started on Earth. More and more scholars are starting to believe that life as we know it actually started on Mars and it somehow reached Earth. Recent evidence shows that this could have been a possibility. Things such as NASA’s data showing that there was water on Mars about 3 billion years ago make us believe that there is a possibility of life on Mars before life on Earth.
According to a recent study, ancient Martian microbial life may have caused the climatic change that degraded the planet’s atmosphere and ultimately caused its extinction. The new idea was developed from climate modeling research that recreated bacteria that produced methane and consumed hydrogen when they lived on Mars some 3.7 billion years ago. Atmospheric conditions at the time were comparable to those on the old Earth at the time.
The reason for life on Mars is due to the atmospheric compositions of the two planets and their respective distances from the Sun explains why life flourished on Earth while dying out on Mars. Mars was more dependent on a powerful fog of heat-trapping greenhouse gases, such as carbon dioxide and hydrogen, to sustain habitable temperatures for life since it was further from our star than Earth.
Therefore, as ancient Martian microbes consumed hydrogen, a potent greenhouse gas, and produced methane, a significant greenhouse gas on Earth but less potent than hydrogen, they gradually ate into the heat-trapping layer of their planet, making Mars eventually become too cold for complex life to evolve.
The researchers are interested in learning if any of these ancient bacteria survived in order to provide support for their idea. Satellites have found methane traces in Mars’ thin atmosphere, and NASA’s Curiosity rover has seen what seems to be “alien burps,” which might be proof that the bacteria are still present.
According to the researchers, their results raise the possibility that life may not always be fundamentally self-sustaining in favorable environments and that it is capable of quickly wiping itself out by unintentionally damaging the basis for its own existence. Mars had been exemplified by some scientists as what Earth could become due to Global Warming and other factors that affect the ecosystem.
