I think there are aliens out there, we can't deny that. There have been recordings of them for ages long ago. They're watching us but due to our violent nature they probably won't publicly show themselves out of fear that we might think of them as a threat. A lot of people claim to have seen them and there are many stories about aliens. We haven't found the smoking gun yet. But there is a lot of overwhelming evidence that other beings have been here and visited us.
