The other problem with UFO's is of course, that they would have to travel at close to the speed of light in order to reach Earth, from another planet that we have not thoroughly examined with telescopes. At least they would if they wanted to reach here in a reasonable amount of time, and assuming they cannot violate the known laws of physics. (Due to entropy ever increasing, it is reasonable to assume any other physical life form in the universe would have a limited life span.) Time dilation caused by approaching the speed of light, is about the only way life forms could travel between stars at subluminal velocity.
