Description

One of the most popular questions today is “are we alone in the universe?” Believe it or not, you’re in the minority if you believe that absolutely no intelligent life exists in the universe. In the United States alone, at least half of all Americans say that we’re not alone in the universe. Fifty percent of Americans already believe that there is some form of life on other planets, while only seventeen percent think that there isn’t. A quarter of Americans believe that intelligent extraterrestrial visitors have already come to Earth and have been doing so for a long time.
