Superpowers or Historical Moment

If i could have any superpower i would wont to do all of them so i could save people from dying and do what i want when i want to. Posessing the power to go back in time i would go back and stop war from starting and i would make it so i could no my real dad so he would still be alive and not die in a shoot off with the police. I think it would be awsome to lift cars and trucks with my mind and be strong enough to lift a buildings so i could save people stuck under fallen down buildings or stuck under cars.
