The Conspiracy: James Bond is not one particular agent, but a code name given to each agent as the previous retires.

The evidence: Though unintentional and not relevant to the books, this actually makes perfect sense in the movie universe. Bond remains an untouched 30-something while everyone around him has aged mercilessly. Further evidence lies in the fact that the titles “M” and “Q” are also passed down from agent to agent. I wonder what Ian Flemming would think.
