I'm curious. Why do you believe he is wrong?
Ok. I am simply answering your question. I am not trying to convince. Nobody has to agree with me.
AND I've already made up my mind. You asked, you get:
1. I agree with the book Conviction of a Time Traveler
2. John Titor most likely represents an entire team of people. Different grammar styles exist in the Titor posts because different people wrote them. This does not mean that John Titor is a hoax, but rather, a team of people were or are still are involved.
3. There is a possibility that the story Titor posted may not be 100% true or literal. This does not automatically make it a hoax, though. For example, nobody, except for a few select people of course, knows if “Kay” is really his mother or if “he” really sold oranges in his future. Think about the possibility of this information referring to something completely different. Does the story contain hidden messages to other time travelers? Is the story a warning meant for someone specific or even for people who may figure it out? Did the story even lend a totally different purpose that only the 177th knows about?
4. Contrary to popular belief, almost all of Titor’s “predictions” have come true. (People can look them up themselves. I'm not going to list them here). Predictions alone are not sufficient evidence to determine if someone is or is not a time traveler, however. Here is a good example of why. Let’s pretend, for the sake of conversation, that I am a time traveler. I, personally, do not like sports. I don’t follow sports and I know very little about teams, scores, etc. Why, then, would I know the score of football game? If I do not pay attention to that information now, why would I do it when I time traveled? On a similar note, how would I know the winning lottery numbers on a particular date for every state? Is it logical to assume that time travelers go around collecting this information simply to prove to people they encounter that they are real? Do you really think they keep a personal database for justification purposes? I’m doubting it.
5. Just because team Titor didn't become Batman or Superman doesn't mean he was a hoax. John Titor was on a specific mission. I am doubting his boss told him to stop the Kennedy Assassination or to prevent 911. The mutliple timeline theory would make this somewhat impossible, anyway. He would only be able to change the current time line, not all of them, and apparently not even his own original time line. This is precisely why he could meet himself without ramifications. Please note: I have my own theories about multiple timelines, but this is the information that was taught to me. Feel free to think outside the box and explore other possibilities.
6. I have found evidence in books such as Alas, Babylon and the Bible.
7. I have been doing investigational research that I don't plan on sharing. Only 2 other people know.
8. I have a mentor that has taught me many things about Titor AND time travel in general.
Those are some of the reasons.
Awaiting public flogging. I'm used to it. I don't care anymore.
