3 giant spaceships heading for earth? Is this real? ENd of the world?

Who said they are going to attack earth? What crap is that. Only last week they were saying that ufos and such did not exist, now they are saying that 3 large alien ships are going to attack us. Have we as a race received a declaration of war? If they are real then the possibility of them being friendly is far more likely as we are about to go through a dimensional shift in 2012 to 2015. and the word is that we are going to be isted by some very friendly aliens. If they are bad then watch the night skies as there are others who will not permit the destruction of this planet nor it's inhabitants. It is getting very close for the people of planet earth to wake up and wake up quickly as time is now running out.
