Much has been written and many movies filmed about the aliens, especially in the domain of science fiction. But what I want to say about aliens, and from the perspective of everyday life?

Even if you are not a fan of the topic, surely you are wondering how it would be if aliens come to our planet? It does not matter whether you believe in their existence or not. Ask yourself hypothetical and try to answer that question, if you have not already read so far research on the subject.

In contrast to that vision presented by the Hollywood and literary templates on this topic, scientists say that our everyday life would not change significantly.

Today, in fact to all generations, aliens as a concept became a big part of the culture so that it does not make so extraterrestrial. Harrison argues that if extraterrestrial life exists at all, is more likely to be detected in the form of microbes on Mars or signals from distant planets. Harrison also does not rule out a number of historical evidence to suggest that mankind is very easy to become accustomed to the idea of the existence of life beyond Earth.

For example, over 80 percent of the faithful claimed that contact with intelligent aliens would not have shaken their personal approach to religion. At least so says the survey results to Ted Peters, a theologian from the Pacific Lutheran Theological Seminary of Berkeley in California.

A third of of the faithful still admits to lead to certain religious crisis. Interestingly, two-thirds of "infidels" of thought to lead to a general religious crisis.

If life beyond the planet Earth really existed, it would probably be an intelligent, domination prone species like us. His ultimate conclusion is that "we never had visitors from outer space, nor is worthwhile to establish centers to detect and search for them in the hope that one might occur." They do not exist, and we are alone, says Conway.
