I love the concept of UFO's and find them fascinating...
but...
I do not believe we have UFO's circling around the earth. I do believe we are not the only life in this or any universe. But I am from the show-me state and yes, you have to show-me there are UFO's. In other words, I need to see them to believe them.
Do you believe in UFO's?
That being said, this video is interesting...
