Little Green Men or just Little Microscopic Organisms?     The question of life on vitiate is a puzzle that has plagued m any mindsthroughout the world. demeanor on Mars, though, is a reality. When you hark back ofMartians, you think of undersize green men who are planning to combat Earth anddestroy totally human life, right? Well, some do and some do not. Though believingthat there are little green men on Mars is just a fantasy, or is it? The kindof life that may have lived there is the kind you would neer consider of givingthe name "Martian" to. They are small organisms such(prenominal) as microbes or bacteria.     Proof of this was fix in a meteorite containing the fossils of the microscopic organisms intact. Two highly regarded chemistry professors fromStanford, Claude Maechling and Richard Zare, dissected three meteorites thatwere about 2 to 8 millimeters long and found trace elements of a big mumbo giantword polycyclic aromatic hydrocarbons. That pretty much means that there one timewas a warmer climate and maybe even lakes or oceans. Life on Mars is now a realidea.     The climate of Mars about 3.8 billion years ago was much similar to theyoung Earth. Microbes and bacteria in all likelihood sprouted everywhere in the warm and close climate. Although now we only see a cold red planet, which was belike dueto a collision of an astroid that would have set back the growth process ofMars, causing it to be a harsh planet. A Viking space vehicle which landed on Marsin 1976 found that the planet was bathed in ultraviolet radiation, "intenseenough so it would probably fry any microbe we know on this planet,"says JackFarmer, an Ames re searcher beetle who calls himself an "exopaleontologist"a searcherfor fossils on other worlds. The redness of Mars is due to the chemical spoilknown as oxidation, which turns iron compounds into rust, and it would surelykill anything that sticks its head up.     "So why do you still believe that there is life on Mars?" you say. Lifeon Mars is not situated on the ultraviolet radiation oxidized surface. Themicrobes are found below it, probably located in the boiling hot springs, or in rimy time capsules. Life here on Earth are located in some strange places sowhy wouldnt the Martian microbes be found in strange places if they were tryingto survive? Scientists have found bacteria here on Earth that were livinginside rocks where they got all of their nourishment from the rocks and fromsome water. Martians probably do the same thing.
