WEll, we will never really know about both until they actually spit it out. I don't really care if Area 51 is real or not. Its none of our business, right? But, for aliens... Yes, they are real. Space is huge. Very, very big. No end to it. The planets we know arn't the only planets out there. What about the other suns? Every star is a sun. Well.. We arn't sure about all of them. Anyways, a lot of the suns will have planets circling around them. And you are saying that we are the only planet out of all the billions of planets out there to have life. That is just completely stupid. I wouldn't be surprised if aliens have landed here on Earth before.
