Who among you believe in String Theory?

Time is interesting, some theories suggest that you CAN travel back in time but there's a problem, why hasn't anyone popped up yet? I see one of a few possibilities, either no one has survived time travel, can't control where you end up in space or it those theories are wrong. I know thats a high level approach, although the question is can you go to the future. I mean we all know where we're going, forward in time. So begs the question is the future pre-determined or is it all random and by chance..
