Life is defined, by Merriam Webster, as “an organismic state characterized by capacity for metabolism growth, reaction to stimuli, and reproduction.” Every single person in the world at this moment is alive and is experiencing life. Planet Earth is home to thousands of species of living animals and was home to thousands more that have now become extinct. Humans have only existed a fraction of the time the Earth has. Many animals predate our own existence. Throughout the millions and billions of light years there are in our observable universe, could our diverse green planet truly be the only one to habit life? Could there perhaps be another planet similar to Earth in a distant galaxy? Although, life has …show more content…
They have been searching the red planet for life and have come up short in finding Martians, for the most part. Now, even though big green “Martians” that we all are familiar with because of Hollywood depictions have not been found; there could very well be microorganisms deep to the planet’s surface. John Prytz has written an article explaining the findings of life on mars. In the article, Life on Mars, he states:
The two Viking landers, equipped with three separate life detection experimental techniques, all scored positive hits. It was only because the detection of organic molecules proved negative that it was thought prudent to look at exotic inorganic soil chemistry as an alternative explanation for the positive life detection results. There are those scientists involved with those Viking experiments who still maintain that microbial life was detected on Mars in 1976. Certainly it’s not 100% proof, but it’s certainly a pro-life run on the scoreboard.
Secondly, there is the evidence from the Martian meteorite found in the Antarctic (ALH 84001). Recall there was four separate and independent reasons for coming to the conclusion that the meteorite contained fossil microbial life forms from Mars. While each taken apart could have a non-biological explanation, the four together were highly suggestive of microbial life on Mars. Make that two runs on the …show more content…
Many people have different opinions on the topic. The only thing needed to end this debate is to actually find legitimate life, which has proven very hard to do. Humans may very well be the most superior life form in the universe. There is no evidence to debunk that statement. Maybe the only other type of life that exists are minute organisms not able to be seen with a telescope. Which makes finding extraterrestrial life that much harder. Concluding that life does not exist would be a fallacy in of itself. Even though life on other planets has not yet been found, does not mean it doesn’t exist; there are habitable planets all throughout in our universe, and Mars may very well have had living creatures on
