What's your favorite conspiracy theory?

Mine is the Mandela Effect, it's actually wild. The fact that so many people swear they remember things differently—like the Berenstain Bears spelling or that Shazaam movie that never existed—lowkey makes me question reality. Like, are we just bad at remembering stuff, or did we actually glitch into another timeline? I know it’s probably just our brains messing with us, but still… kinda sus.

What about you? Got a favorite?
