Based on famous astrophysicist Stephen Hawking, aliens are not to be trifled with. In the fresh Discovery Network TV series, Mister. Hawking claims it is probable aliens exist, given the vastness of the universe, and that we really do not want them down here on our planet, considering they will be very likely to view our treasured blue marble of a planet as a tasty, exploitable useful resource.Do you actually believe in aliens?
