　　Mankind have been actively seeking out foreign life via transmitting pre-emptive signals to the vast universe for decades.While the presence of extraterrestrial beings has not been confirmed,it is never wise,in my opinion,to present the existence of human life to the universe.

　　Scientists going for proactive contact with outer space are confident in positive consequences for our race.They believe,if this ambition realized,our civilization can profoundly and positively benefit from message recipients as whoever can reply or trace it certainly stands on an equal or higher position in technological progress.Presumably,the respondent or the visitor will have inter-planetary intercourse with good intention,which accelerates our technology rapidly and enables our cosmic era.As well as this hope,this action also indicates the desire in universal exploration and as the means of this communication varies through time and technological advancement,humans will eventually colonize other planets,solving global issues by expanding territories and obtaining immense resources.

　　However,despite both lures mentioned,this could be a fatal threat to Earth.When Christopher Columbus arrived America,that never turned out well for the natives.In fact,as long as two civilizations have encountered with each other,the superior one is highly likely to colonize the lesser developed one via warfare or cultural assimilation,and once natural resources are involved,physical conflicts become unavoidable.In this scenario being discussed,human kind is probably the natives.

　　In conclusion,it would be irrational to count on aliens whose hostility may never be predicted and the dominant race on earth must only rely on itself in exploring the deep space.
