Maybe we really are alone in the universe

Start by imagining our own technology 500 years hence. That is completely beyond my ability to conceive. 

Now what if the alien life were 500 million years ahead of us? They would be god-like, with technology absolutely beyond our comprehension. They would be curious, so by now they would have found us. They would certainly be capable of choosing whether or not to make contact. 

However, there is no evidence of their existence. Perhaps they have turned their noses up at us and moved on? 


But my hunch is that we are the most advanced species in the Universe, certainly in our galaxy.
