I don't get why people who are convinced alien life exists, that they are vastly technologically superior to us. I just don't get it. Could it be we are more technologically advanced than they, and several generations from now, WE will be the ones making first contact? What I'm asking is......why do aliens have spaceships and the ability to travel through space at very high speeds while we don't? How do you guys know they can do this FOR SURE? Any proof?
