Before I answer above question I would like to give you the definitions of alien. According to Oxford dictionary, alien means species which come from another world supposedly or extra terrestrial. From Cambridge dictionary it means that it comes from a different country, race, or group. It is strange and not familiar with human because it relates to creatures from another planet. Based on two definitions above, the writer makes a generalization that alien, we call as strange and unfamiliar appearance, is human’s friend or family who live in different shape or time dimensions. Alien is human’s life mate in this great world.
Recently, there many researchers, scientific forums, scientific journals, and private department that gives their great time to discus about it. The researchers have conducted a secret research on alien. They are eager to know who alien is, why unidentified flying object (UFO) is identical with alien existence, and why alien makes human, in this case people feel afraid of their existence. They have spent million dollars for knowing more about them. They study them seriously in a long period. They do this because they want to open the mystery of alien.
As stated as title of this short article, the writer delivers three main points why they appear in this world. First, Alien is human friend. This statement exactly means that beside creating human, God also creates alien. Their existence is the same with human’s existence. They look like a human but their performance is strange and unfamiliar. According to the ancient mythology that before human being was created, God has created alien. Long time before man appears in the world, alien has appeared. So, as friend, may be aliens want to know more about their friend, family namely human being.
Second, alien appears in the world because they want to know how far the development of human in all aspects such as technology, appearance, ability in survive, social, etc. Actually, aliens want to know more whether human’s technology can be higher than alien’s technology. Because of this, sometimes aliens come or appear in the world by driving their UFO, a super highest technology media in their transportation way.
Third, different with the two points above, sometimes aliens appear in the world because they have negative reason. They want that the super creatures in the world are them. They don’t want human being can be super man with super technology. So, their motif is they want to show of force that they are the great in this world.
In short, based on explanation above there are three reasons why alien appear in the world. As human we should believe the existence of aliens. They are actually human friends and family which live in different shape of life, time, and condition.
