Life Developed Only on Earth Essay

animation developed hardly on this one small planet in this one small galaxy. There are several reasons to explain this and near of these are the following First of all, water is sufficient on state making it fit for manner to exist (BBC, n. d. ). Second, oxygen is available on Earth for a life to carry on living (BBC, n. d. ). Third, uncomplete earth is too close nor too far from the Sun, thus uncomplete it is not too warm nor is it too cold to live in (BBC, n. d. ). Fourth, the chemicals necessitated to create a living cell are more than ample (BBC, n. d. ).Fifth, a considerable amount of plant and animal species have already developed and adjusted to the environment (BBC, n. d. ). Sixth, the surface of the Earth is perfectly intentional since it amazingly protects it from the rays of the Sun (BBC, n. d. ). This is the same reason why the Earth gets the steady off temperature while other planets are either extremely hot or excessively cold (BBC, n. d. ). Consequently, th is also made it possible for water to be available in its liquid state (BBC, n. d. ).Seventh, even if it has been said that life exists in Mars, there are no evidences that support such in time (Fisher, 2005). Furthermore, telescopes are not that good enough to provide details as to whether life really exists there or not (Fisher, 2005). Moreover, to declare such a statement would entail a closer scrutiny of the aforesaid(prenominal) (Fisher, 2005). Eighth, unfortunately, nobody from Earth can leave for Mars (Fisher, 2005). In fact, even NASA say no such mission bequeath be move for several years (Fisher, 2005).Last but not least, the Earth is the only planet which has a magnetic field that turns away dangerous particles of quadrangle radiation (Fisher, 2005). This means that other planets have a much lesser air and have a much colder temperature, thus living will be quite impossible (Fisher, 2005).ReferencesBBC. (n. d. ). Why is There lifespan on Earth?
