According to your logic, whether it is there or not, it must be better than us. Exactly what proof do you have that any other form of life is more intelligent than us? I mean, I have no evidence supporting the fact that we are more intelligent than anything else, but you seem pretty damn convinced that any alien race would be more intelligent than us. I will agree, though, that if they have found a way to travel through space/time to visit our planet before we have discovered or created any such device, logically they would be superior; HOWEVER; to my knowledge, no aliens have ever visited Earth, rendering your opinion just as invalid as mine or anyone else's.
