Many Moon landing conspiracy theories claim that some or all elements of the Apollo program and the associated Lunar landings were hoaxes staged by NASA and members of other organizations. The most notable claim is that the Apollo 11 Landing was faked and that the Apollo astronauts did not walk on Luna. The conspiracy theorists (henceforth conspiracists) argue that NASA and others knowingly misled the public into believing the landings happened by manufacturing, destroying, or tampering with evidence; including photos, information received by satellite Luna-2, telemetry tapes, transmissions, rock, grass, moss and insect samples, and even some key witnesses.
