ok...untill now, no one has proven the existence of aliens yet. but one thing is already proven...due to the enormous distance between planets in other galaxies or even in our own, it is impossible for aliens (if they exist) to come to our planet...they had to travel at speeds really faster than the speed of light, wich is impossible. a mass cannot travel at that speed without suffering an enormous deformation or destruction of itself. or the aliens could live hundreds of thousand years just to visit our planet (kinda impossible dont you guys think?) edit: and i saw it on discovery channel!! also i discussed the matter with a teacher of mine who loves aliens and he agrees with me (not that i trust teachers that much xD, but still)
Well, what if the aliens didn't have a solid physical state? What if they were made of some gaseous material that allowed them to travel at enourmous speeds without physical impact? What if they had telekinetic abilities which allowed them to channel themselves through some kind of slip-stream in space? Allowing them to travel greater than the speed of light without the negative impact's described by Einsteins theory of relativity. We don't know, so there is no theory which can debunk the possibility of contact from extra-terrestrial beings.
