Let's start with one of the most well-known conspiracy theories – the moon landing hoax. It is believed by some that NASA faked the moon landing in 1969 in order to win the space race against Russia. Proponents of this theory point to various inconsistencies in photographs and videos from the mission as evidence that it was all staged on a movie set. However, overwhelming scientific evidence including moon rock samples brought back from Apollo missions and reflectors left on the moon's surface have convincingly proved that humans did indeed land on the moon. So, while this conspiracy theory continues to persist, it has been debunked time and time again.
