Sure, here are five bizarre conspiracy theories about natural phenomena:

1. **Government Weather Control**: Some believe that extreme natural phenomena such as hurricanes, tornadoes, and droughts are caused by governments through advanced weather manipulation technologies such as the HAARP project. This theory claims that governments are using these techniques to achieve their own political and economic goals.

2. **Flat Earth and Earthquakes**: The flat Earth theory suggests that earthquakes are caused by some form of government manipulation to keep the population under control or to cover up the truth about the true shape of the Earth. Some believe that earthquakes are artificially manufactured to perpetuate this supposed conspiracy.

3. **End of the Natural World**: Some conspiracy theories claim that natural phenomena, such as volcanic eruptions or extreme weather changes, are actually signs of the impending end of the world. These theories often involve apocalyptic interpretations of natural events, claiming that they are signs of an impending catastrophic event.

4. **Alien Manipulation**: Some people believe that natural phenomena, such as the Northern Lights or mysterious lights in the sky, are actually caused by alien activity. This theory suggests that aliens are manipulating the weather or sending signals to Earth as part of an unknown agenda.

5. **Underground or Oceanic Creatures**: Some believe that natural phenomena such as tsunamis or tidal waves are caused by unknown creatures that live deep within the Earth or ocean. This theory speculates on the existence of giant or monstrous beings that have the power to cause these natural events as part of their own agenda or defense.
