World's leading scientist Stefen Hawkins says that extraterrestrials are out there and we humans should avoid them . We are all aware of the fact that aliens are one of the biggest mysteries of our Universe. He believes that aliens are not just in planets but also in stars or may be even they are floating in interplanetary space .His logic is that the Earth is not the only place where life has evolved and we need to find out that how the aliens look like.
He has published his documentary series where in one scene shows nerds of two- legged herbivores browsing on an alien cliff - face where they are picked off by flying , yellow lizard- like predators . Another shows glowing fluorescent aquatic animals forming vast shoals in the oceans thought to underlie the thick ice coating Europa , which is one of the moon of Jupiter.
Hawkins is using these scenes to lead us to serious thought that the aliens could be intelligent and can pose threat to human lives.
He says that aliens could just raid our planet for resources and then move on.
Acoording to him , " We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet . I imagine they might exist in massive ships , having used up all the resources from their home planet . Such advanced aliens would perhaps become nomads , looking to conquer and colonise whatever planets they can reach."
