Time travel can only be accomodated by travelling back in time for it is there that the time line exists, not in the future.

Somehow, that doesn't sound right. Assuming there is a timeline, an entity living somewhere on that timeline should be able to travel forward to our time as well as backwards, as you say that we can. Just as they dwell somewhere along the timeline, then we also dwell somewhere along it and not necessarily at the end of it. The timeline would extend ahead of us as well as behind us. No?

No, consider that you live on the edge of time. That most forward point in time. If time exists after you, as in the future, than you would have to do no more than to sit down and wait for all the future has to offer. You would have to do nothing. Things would just happen. But how could this be. How could you get that perfect job if you never went for an interview. How would you ever meet that perfect mate if you had never gone to that party or that bar or had accidentally run into that someone in an elevator The tmeline exists only in our past and we can only travel to the past.
