Sorry, but I have don't believe we are being buzzed by Aliens.
Firstly they have no idea we are here,according to SETI, very few of our radio and tv transmissions will have escaped into space and although they travel at the speed of light they get weaker the further they go and will eventually get drowned out by the background electromatic radiation caused by the 'big bang'.
Okay so now we have space craft that have left the planet and now solar system, such as Voyager, are not that far out of our solar system
Then there is the small question of interstellar travel, being able to travel at the speed of light is one thing, but traveling such distances is another matter.
Why if there are such life forms do they not get in contact with us?
Why not land in Hyde Park?
I am not saying that the universe is devoid of life, just I don't beleive in UFO's
