When a common man hears the word ‘aliens’ the first thing that comes to his mind is, a creature with a different appearance. Yes, what he is familiar is the extraterrestrial beings that he had seen in fiction books and movies. But the word has a wide meaning when it comes to politics, law and biology. But the meaning of the word in all these contexts remains the same ‘foreigners’.
When discussing about aliens, it is better to start with what human beings are most familiar with or what is digestible for them. In the world of ‘astrobiology’ it is something connected to astrology. They are those extraterrestrial living beings coming from outside earth. But it never claims that a life exists beyond the world. It never questions also. It is left to discussion for the scientists and research fellows. It is beyond the limits of the thoughts of a common man.
But then he can imagine on aliens also in the similar way that he imagines various other things of regular life. He creates beautiful ideas about this life and imagines himself meeting such creatures in a visit to the solar system. The funny thing about this is that even when he visits there, though it is he who is alien in that land, he tends to call the native beings as alien.
Kids are often attracted most by this extra terrestrial concept. It is therefore in their books and their world that aliens gain high importance. Often they wonder about such a life, but they are ignorant of the realities. No wonder why books for children come up with fantasies on all such concepts of aliens and they capture special place in their heart.
Another concept of aliens come into picture when a person tries to move to a different country and establish a living there. But there arises lot of complications all related to law. As human beings are reluctant to trust a stranger and to welcome them into their life, these aliens are not able to receive an easy approval there. Aliens have been reasons for several problems in these countries and that is the reason behind such a fear.
When talking about other living beings the animals or plants brought to a place from a different habitat is referred to as aliens. These living beings fight with the natives for a living as they suffer too much when the habitat changes. They have to adapt in the new surroundings, which is difficult as far as these creatures are considered. This is because a reproduction of their previous habitat as such is impractical. Also the food habits are to be adjusted in a wide range.
As a result of these practical difficulties, these entire species face the threat of being swiped away as a whole. They interfere with the normal life of the native species and thereby make them also endangered. Human beings are usually responsible for the generation of these aliens, which they do for their selfish needs. But then there should be proper care from their part to reproduce the environment as a whole for their existence.
Man often understands ‘Aliens’ as outsiders. The broader sense as a foreigner lies beyond their thoughts. They discuss all these meanings when a matter arises in its context. There can be controversies as well, but still then it is interesting.
