ill give you an example. lets say bob has a time machine. bob wants to go back and meet his long-dead dad. bob meets his dad, and they talk. bob's dad doesnt meet bob's mother because he was talking to bob instead. therefore, bob wasnt born. but now, if bob isnt born, he wouldnt ba around to distract his dad, and his dad would have met his mom and gotten maried and have bob. but then bob would exist, so bob would mess it up, so bob wouldnt exist, and so on, and so forth. |
