4 reasons Mars might hold life - Business Insider
Using the hypothesis set up by Urey and tested by Miller, this paper looks at whether these prebiotic conditions ever existed on the surface of Mars, thus making it possible to have or have had life on Mars....

In 1996, a team of scientists led by David McKay announced the discovery of possible for ancient microbacterial life in a chunk of meteorite (3.9-billion-year-old ALH840001) that came from the planet Mars. In February 2001, at least two teams of researchers announced finding chains of magnetite crystals similar to those made by bacteria on Earth in ALH84001 and in at least two other Mars meteorites that range in age from 1.3 billion to 165 million years ( and new briefs). In February 2006, a team of researchers announced the discovery of a mix of carbon compounds filling tiny veins in the which exhibits similarities with those found in fractured volcanic samples from the Earth's ocean floor raising the possibility that bacterial life produced the Martian material (; and ).
As each day passes, the worlds science society obtains more and more evidence that suggests the possibility of life beyond Earth. This all comes from expeditions such as the Galileo space probes around the Jovian planetary system, and the Voyager missions to Mars. As a result of this extensive and ongoing search for any extraterrestrial life, Humans have come a squeak closer to guessing weather or not another species is surviving in the cold wastes of outer space, as they ask “Is anyone out there?”

Life on Mars: Nasa finds first hint of alien life
So what will the fabled life on Mars actually look like? How on earth, if you’ll pardon the expression, will anyone survive on this great freezing ball of basaltic rock as it hurtles through space at an average distance of 142 million miles from the sun (compared to Earth’s 93)? Bear in mind its average temperature is a chilly -81F (or -63C); its gravity is about 38 per cent as strong as Earth’s; and crucially, there is almost no readily available oxygen.
The first hints of life on Mars have been discovered by Nasa.
On February 21, 2005, Vittorio Formisano, chief scientist for 's Planetary Fourier Spectrometer (PFS), announced that the Elysium Planitia (whose southern region has evidence of pack ice in a dust-covered frozen sea) is the region of observed to have the most methane (CH4) coming out of the surface. Since most of the methane in Earth's atmosphere is produced by microbes living in the soil, Formisano ventured that life is the most likely explanation for methane in the Martian atmosphere as well. In September 2004, Formisano reported that concentrations of water vapor near the Martian surface are two to three times higher along Elysium Planitia and two other regions near the equator, than at higher latitudes. Although methane may be more concentrated in that area, other scientists note that its presence may be a product of geological activity since Elysium Planitia is one of the major volcanic regions on Mars. On February 24, 2005, however, Formisano announced the detection of sufficient amounts of formaldehyde (CH2O), mostly likely from the oxidation of methane, which suggest that the annual emission of methane into the Martian atmosphere is too great to be produced by any known geological processes (Mark Peplow, , February 25, 2005).

The Mars life theory suggests that rocks rich with microorganisms could have been ejected off the planet's surface from a powerful impact, eventually making their way through space to Earth. It's not a stretch to imagine, because . None of those, however, have shown signs of life.
