Essay On Extra Terrestrial Life

922 Words4 Pages

The current evidence is insufficient to prove the existence of extra-terrestrial life.
Since long ago, people have always been fascinated with the idea of extra-terrestrial life. We have sent countless of spaceships from many different countries into space, to delve deeper into understanding the universe and outer space. But for so long, we have yet to find any hard evidence of extra-terrestrial life. With all the evidence we have at hand currently, for now, we cannot prove that extra-terrestrial life exists.
Most people find it hard it to believe that aliens exist as they believe that if aliens do exists, then they would have met those aliens by now. This belief reflects an ignorance of the incredible size and spaciousness of the universe. …show more content…

Within the Solar System, there are instances of places which are habitable for life. Jupiter’s moon Europa where below its icy surface, it is believed to be habitable for life. Saturn’s largest moon, Titan can possibly sustain life due to its environment containing hydrocarbon (Atkinson, 2015). However, having an environment suitable for life does not necessarily mean that there is such existence of life. The creation of life on Earth did not come easily since our organic material was formed in a high energy environment. During our earlier years, the earth was subjected to harsh lightning storms and tectonic activity, an environment which produced high heat and pressure which is required for organic materials to form, allowing for life to develop (Brahic, 2008). If we were to support this theory of how life came to exist, it would be highly unlikely for much planets to develop life as this necessary environment is hardly present in other planets like ours. Hence even if other planets are available to support life, it might not be able to create life like us in the first place. Thus, we should not judge quickly that there is enough evidence to prove the existence of extra-terrestrial

    In the totality of his essay, Carr provides evidence to support his positon, like of the University College London study on database user behaviour to illustrate that web users skim, rather than closely read online articles. Providing evidence, and making connections is characteristic of insight and we can see this in Carr’s essay. Instead, Lightman provides tentative solutions, with hypothetical reasoning, “If some cosmic intelligence created the universe, life would seem to have been only an afterthought. And if life emerges by random processes, vast amounts of lifeless material are needed for each particle of life. Such numbers cannot help but bear upon the question of our significance in the universe” (Lightman 507).

  • Organic Meteorites Sound Like Science Fiction

    197 Words  | 1 Pages

    This idea of organic molecules traveling to Earth on meteorites may sound like science fiction, but it was actually supported by reasonable evidence. For example, scientists found that organic molecules can be produced from simple chemical present in space and this is due to the conditions that could exist in space for example like high UV irradiation and low temperature. Scientist also know that some of the organic compounds are found in space. But the important thing is that, many meteorites have turned out to contain organic compounds which came from space and not from earth. There was one meteorite that came from Mars and contained organic molecules with multiple ring structures.

  • Panspermia Hypothesis

    1177 Words  | 5 Pages

    Some proposed that evidence for Panspermia seems weak, and there is the view of Crick (Crick, 1993) who suggests that the implausibility of the RNA world may imply that life that we know of did not originate on our planet, but instead on a planet where there might have been conditions that were selectively favourable for the evolution of RNA. Implications of this are that it is much less adverse for RNA to have existed on a more favourable planet than existing on Earth at a time which would not have favoured the origin of the RNA world (Crick, 1993). The second hypothesis that I will be evaluating is the Oparin-Haldane hypothesis, a theory put forward separately by biochemists Alexander Oparin and J. B. S.Haldane who both subsequently released independent papers. Their theories stated that life started to appear in the oceans during a time of atmospheric reduction.

  • Essay On Why Do Aliens Exist

    More than 510 testimonies and sights of aliens have been coming to light for ages. Most people think that aliens aren’t real, probably because their existence sounds crazy, but also because for some reason powerful Governments always try to make people believe that. What is weird is that even though a lot of important people have said that they exist and that they are among us it is still a myth. In this essay I’m going to show some proves that show Alien’s existence in Earth and in the Universe. Area 51 has been a mystery for over 20 years and even the Government has declared that it exists but they never say what is its use, that‘s why most people think that because of its location and the posters that say things such as “Get close, get shot”

    An organism which does not require water is never discovered. While some organisms require less water than others, e.g., cyanobacteria Chroococcidiopsis, for instance, requires minute quantity of water that biologists even think it may be able to survive on the arid surface of Mars. Every organism that is alive needs water to survive. In fact, without water, life on Earth would never have started. Water is also one of the reasons that there is no life on any other planet in the solar system.
