"Alien Theories" refer to various ideas and hypotheses about the existence of extraterrestrial life and its potential interactions with Earth. These theories often explore the possibility that intelligent beings from other planets, such as those in the Milky Way galaxy, may have visited or influenced human civilization. Some proponents suggest that ancient structures, like the Pyramids of Giza, were built with the help of advanced alien technology. Many people are fascinated by the idea of UFOs (Unidentified Flying Objects) as evidence of alien encounters. Some theories propose that governments, such as the United States, have concealed information about these sightings. Others speculate about the implications of discovering life beyond Earth, including the potential for communication or even collaboration with alien civilizations.
