While I admit its extremely unlikely there is nothing actually impossible about aliens visiting the earth. We know sophisticated life can evolve on a planet, we know life develops technology and we know you can travel between the stars. However unlikely it is still possible. I'm a sceptic myself but we shouldn't just dismiss the possibility. Stars move in space, when early man existed 70,000 years ago there was another star within a light year of earth (Scholz star). It was at the outer edge of our solar system. Over billions of years many stars have passed close to our solar system or even through it. Sub light speed is certainly possible for a spaceship. A star 4 light years away could be reached by a ship at half light speed in 8 years. With so many people believing the plain ridiculous like prophets flying about on horses or the sea parting we shouldn't lump the unlikely with the impossible.
Saying that it probably won't be a good thing if alien life turns up that could be the end of humanity pretty much immediately. Personally I think we should keep our head down and not send out signals which aliens could receive. Maybe that is why we don't hear anything as most alien civilisations aren't stupid enough to broadcast their location.
