There are several reasons why it might be a good idea to steer clear of extraterrestrials, despite the continuing search by scientists. These reasons could include serious environmental cross-contamination, the possibility that certain cultures on the planet might react negatively to an alien presence, be it small or large, or even a doomsday level invasion from an advanced aggressor, forewarned by Stephen Hawking.
However, there are reasons that contact with aliens might be a good thing. Scientists at SETI (Search for Extraterrestrial Intelligence) Institute think so; they’ve worked hard sifting through mounds of radio data from the cosmos for decades hoping to make contact a reality.
But are there any benefits to our civilization in finding E.T?
