Is this a proof that traveling back in time is impossible?

Is the fact that no one has ever traveled back in time from the future a proof that traveling back in time is impossible? But if a person can travel back in time doesn't that mean relative to the people in the past the future would seem like it has already happened?

Please provide proof for the statement that no one has ever traveled back in time.

But if a person can travel back in time doesn't that mean relative to the people in the past the future would seem like it has already happened?
That one is too convoluted for me.

I firmly believe that it is impossible to travel backwards in time, but I do not base that on empirical evidence and I am quite sure that neither do you, despite your statement to the contrary.

This forum is about science-fiction and fantasy. That is: discussions of a reality in an alternate world. Not speculation about this world.
