There have been found methane on Mars, but that would not necessarily mean, that there would be found living bacteria. The gas might come from the bacteria, what have been dead the long time ago, and the gas might be stored inside the Martian landscape. Another change would be that the Methane and carbon are from the space, and dropped to the Mars with the meteorites. The methane would be the more interesting thing than free carbon because of this chemical combination forms on Earth mainly by the organic material rotten in the anaerobic conditions. And the carbon is one of the basic elements of nature. That element is found on the asteroid belt, and there have been found asteroids, what are pure carbon. Those asteroids are very uncommon particles in the group of little planets.
Actually the moons of Mars, Phobos and Deimos are only known that sized carbon asteroids, what are like diamonds, but carbon asteroids are actually very abnormal in that area. Some persons believe, that they are formed the organic material, what was blown to space when the asteroid hit to that planet. The carbon is the base element for life-form like us, but there are also stars, what is forming of this element. Some white dwarf stars are forming carbon, and they are like giant diamonds because the carbon has been stunned soo tight when the star has been destroyed in nova-explosion, where the outer layer would be pushed to space. Little bit bigger star would end the life as the supernova, and the result would be Neutron star.

But when we would get back to Mars, we can think that there would be the connection between seasons and methane release, the reason for that might be, that during the summer the surface of that planet would be getting warmer, and then there would be released more methane than in winter, and that would explain the increase of the methane flow. And in this case, there have been lifeforms on Mars, but then some meteorite hit to that planet, what lost its atmosphere, and probably the major part of the lithosphere have been blown to space.
Those organisms were quite simple bacteria, what could be forming to the intelligent life without that meteorite. But some scientists have given the idea, that planet Mars have faced two mass destructions. The first one destroyed the lithosphere of the planet, and if there would be some complicated organisms on that planet, they would be blown to space with the lithosphere, what has been lost, and that would be killed almost all of the animals and other organisms on that planet.
The gas pressure decreased, and the planet became very hostile for the living. And the final seal for the mass destruction would be the second hit of the meteorite, what caused that the rest of atmosphere was lost in space, and the ultraviolet radiation would destroy the rest of those organisms. But still is change, that some very strong ark-bacteria would live somewhere in the Red Planet. And maybe that organism would seem like the cyanobacterium on Earth. Who knows, what kind of sensation, we would meet on that planet.
