Time travel might be theoretically possible but unless you're talking micro seconds it's still just science fiction and like traveling the speed of light it will never be achieved with matter especially living matter.
Fun to think about though, there's the paradox problem like in "back to the future", go back in time to set up your parents so you can be born.
Personally I think if something happened, it happened and can't be changed.
