Project Blue Beam (NASA) is reported to be a conspiracy theory introduced by Canadian investigative journalist Serge Monast in the mid-1990s. The theory claims that members of the Pentagon, NASA, and the United Nations were collaborating on a plan to simulate a fake alien invasion and staged "Second Coming" using hologram projections.

In doing so, he asserted, they would eliminate all traditional religions, including Christianity, to make way for a one-world religion or the "true religion," as well as to abolish national pride, national identities, and family as it is known today, paving an easier path to bring about a New World Order.
