Extraterrestial InfluenceAll our science, measured against reality, is primitive and childlike and yet it is the most precious thing we befuddle. -Albert virtuosoINTRODUCTIONThere are many things in this world that go unexplained. Not anymore, it was all aliens, everything you cant figure out like, Where does one drogue parachute go when I do the laundry?, and How do you get the caramel into the Caramilk bar? Aliens. Earth has been profoundly impacted by extraterrestrials in its short history. Everything from furnish feel-giving chemicals and wiping out the dinosaurs with meteorites to influencing human culture and evolution. The whole world is filled with evidence of extraterrestrials, though it is usually denied and ignored by governments and academics. This essay will stand a brief analysis of extraterrestrial events or evidence thereof the were especially significant.THE BEGINNING OF LIFEEvolutionary theory suggests that life on worldly concern has been developing for mil lions of years into more and more complex organisms. These organisms evolved from inorganic molecules through the release of UV, heat and electrical energy in the atmosphere of early Earth. This theory was found to be valid by Stan Miller in 1953, who through a series of tests managed to create some hydrocarbons and amino acids out of chemicals that were present on earth 3.5 billion years ago. These hydrocarbons and amino acids are very susceptible to oxidation and would not exist for very long in an oxygen establish environment. Though there was very little oxygen in earths atmosphere at the time, the large amount of energy present would have easily electrolyzed some water and produced oxygen gas, which is bad for the amino acids. A much more likely place for amino acids and hydrocarbons to develop would be in large dust clouds in space, such as the one that condensed to form our solar system. Evidence for this theory comes from the many carbonaceous chondrite meteorites recovered (these same life giving meteors have also led to many mass extinctions in earths history). A NASA research group examined one such meteorite in 1970 and found a high concentration of amino acids and hydrocarbons than are present on earth today (Kvenvolden, K., Lawless, J., Pering, K., Peterson, E., Flores, J., Ponnamperuma, C., Kaplan, I.R., Moore, C., 197). In addition the amino acids had a higher concentration of L enantiomers than R-enantiomers, as is seen on earth (Chyba, 1997). This seems to suggest that the basic chemicals for life were derived extraterrestrially.
