1. Bigfoot
    I think he at least existed at some point in time
  2. Loch Ness Monster
    Same as Bigfoot, probably not around still
  3. Aliens
    Fox mulder n Dana scully
  4. The Lincoln and Kennedy assassination connection
    Too many similarities TBH
  5. Paul is dead
    I watched a documentary about Paul McCartney getting in a car accident and dying right in the middle of Beatle-mania so their management hired a lookalike and even gave him plastic surgery to keep up appearances....really believable
