I would be not so sure, since we didn't understood much of the whole thing yet
However, let's assume you got a time machine which can bring back, you need the time machine there in the past too, as to teleport in the past the machine which teleports yourself it is more difficult to think of.
So let's say someone builds a time machine in 2015 and puts it in a secret place underground inside a mountain which you know can't be touched in future. Let him go forward in time, he re-appear in same place in 2030, then let him go on 2050 and so on. Then let him go back in 2030 and 2015 is ok. But he can't go back in 2014 or anyway before the time machine it existed there.
This would explain why if in the future the time machine it will be invented, they did not came here to tell us. It could be in the future, someon invents the time machine then immediately (on that same second), infinite people from the future will come from the past into that first time machine box in a loop changing future , so fast until one of the many futures in the loop includes a world destruction by nukes (very probable in such a loop), which would happen as soon as possible so in the very next second after the time machine it is built.
Accordingly, it is very likely the same day someone evern built a working time machine, the world it will end, by near-infinite loop of future people abusing this by return back in time to change something until one of these future includes end of all, which stops loop and all of humans from doing this.
