I dont know whats going to happen in 2012 but ive been having a real bad feeling and i know its gonna sit on my mind until december 21st 2012. Nostradamous says a comet will hit the earth in 2012 and in the bible codes also says a comet will hit earth in 2012. I think if aliens really exist we`ll probably come into contact with them in 2012 or before then.
