1. 'Aliens' are visiting earth (not proven)

2. Backwards time travel is possible (theoretically impossible as of right now)

"IF" we could build a spaceship that could get to 99.9% of

*c*.......

and "IF" we could manage a stable Einstein-Rosen bridge.....

Neither of which violate GR.......

And we put one half the wormhole on this ship, and accelerated it to 99.9% the speed of

*c* for say 50 years in orbit of the earth, then landed the ship, and took out the wormhole, time dilation would have you 500 years in the future, where you could travel back through time to the point 50 years past the initiation of the original wormhole where the other half of the wormhole still resides.

Couldn't you?
