Ancient Bacteria on Mars.
Souce
For a terrestrial bacterium, Mars is a cold, dry and dead hell, however, for a hypothetical Martian bacterium, the earth would be a paradise where it could multiply full of nutrients, potentially we could use its food and the terrestrial organisms could not stop it because they have never faced something similar.
Souce Mars is ancient
The researchers have carried out their experiments with terrestrial bacteria with an amazing resistance; Scientists believe that Mars met the necessary conditions for life as we know it to arise on it, there was a time at the beginning of its existence when the red planet was a blue and white planet and it was for a period between a few hundred million or perhaps a few billion years; the blue one is because it had rivers, lakes and a large ocean and the white one because despite the fact that the temperatures were warmer than the current ones because it had a thicker atmosphere, it is also true that Mars is further from the sun that the earth and that in the early days of the existence of the solar system the sun was somewhat colder than it is today.

The question scientists have now asked is whether bacteria ever existed, could they adapt to survive the increasingly harsh and extreme conditions on Mars, and in the end be some of them alive or dormant under the ground?
Souce “Conan the Bacterium”
The researchers determined that some terrestrial microorganisms could potentially survive on Mars on geological time scales of hundreds of millions of years, in fact, the researchers discovered that Deinococcus hinococcus radiodurans known affectionately as "Conan the bacteria" after Conan the Barbarian from the movie .
