I do not believe that anyone from outer space has ever visited the Earth, Mr. Bean told news.com.au from his home in Houston, Texas.I guess a part of Mr. Beans mind did not return to earth with him.
One of reasons I dont believe they have been here is that civilizations that are more advanced are more altruistic and friendly like Earth, which is better than it used to be so they would have landed and said we come in peace and we know from our studies you have cancer that kills people, we solved that problem 50 years ago, heres the gadget we put on a persons chest that will cure it, we will show you how to make it. Just like some day, say 1,000 years from now, when we can go to another star and see a planet, thats what we would do because we will know how to cure cancer, cure birth defects, so we would teach them.
