what conspiracy theory do yall believe in?

this is kind of a millennial question i guess but like what conspiracy theories do yall think are real? because i feel like most people believe in at least 1 or two.

i dont particularly believe in any but i find the antartica ones interesting.

examples : avril lavigne and kanye west arent really who they use to be and are clones, moon landing was faked, covid-19 was made in a lab (😒) , amelia earhart was eaten by crabs, etc. etc.
