Page 47 AND NT 3

Page 47 is obviously about Area 51! Riley says something about Area 51, Roswell happened in 1947, and at the end of the movie, the President asks Ben about discussing page 47, and Ben says, "that would be LIFE-ALTERING, Sir." Which might mean, time travel or aliens, but most-likely aliens because of all the other clues. It also might be a whole bundle of a lot of things all together. Who knows? That's just my take on it.
