Who has not heard at least once in life a conspiracy theory. Who has not heard of organizations such as the CIA, NSA, MI 6, etc., or: Bilderberg Group, Trilateral Commission, Vatican, etc?
Who has not heard of conspiracies: New Age, Jewish, Enlightenment, Freemasonry, aliens, Chinese, etc?
Perhaps only those people for whom nothing in the world that does not matter, except food, drink and entertainment.
For the rest: we live in a world of conspiracies and theories.
