Does Life On Mars Exist

Many people believe that there has to be some type of life outside of earth because the universe is so large. The universe is infinite, there has to be some sort of life form out because it would be irrational to think that only earth place out there that has life on it .There has already has been species that were discovered living outside earth like bacteria’s and virus (Ebola) came from space. Life doesn’t have to be only humans but to anything living outside of earth whether it’s a planet, bacteria or an animal. Four lines of proof that do help life did exist on Mars is that a shooting star was discovered and the calcium carbonate it contains originated from Mars, the mineralogy and science of the carbonate globules are good with biologic

McKay et al (1996, p.2) writes that “On Earth, PAHs are abundant as fossil molecules in ancient sedimentary rocks, coal, and petroleum, where they are derived from chemical aromatization of biological precursors such as marine plankton and early plant life” it suggested that water must have been present for these PAH’s to be created. If we can prove Water did indeed exist on Mars then it is possible that life did exist on Mars. “The carbon isotopic compositions of ALH84001 are similar to those measured in CM2 carbonaceous chondrites. Consequently, the carbonates in ALH84001 and the CM2 meteorites are believed to have been formed by aqueous processes on parent bodies” (McKay et al, 1996, p.2) meaning that the rock found must have been formed within a lake bed or a

This is a break through discovery because it proved that some living organisms can survive spaces weather conditions. Extremophile micro-organisms can survive the harshest conditions without oxygen. In space, there must be many organisms like this that have adapted to those conditions. “A study conducted by the American Society for Microbiology and published in the Nature science journal revealed that 377 strains of bacteria may have survived the sterilization process that the Curiosity rover endured before it was launched in an attempt to avoid contaminating the red planet” some of our bacteria may have contaminated Mars and grew there. Commonly, no less than to earth life, micro-organisms structure colonies- groups of phones near one another. Sometimes, provinces need aid the polar relative of an absolute call that arrived for a spot also increased. Different times, states are sorted out bunches for cells, serving one another to develop and also
