Anyway I want to know what PROVES time slows down for something going faster then light, considering we never get anything to go faster then light how can we ask it?

Theoretically, time would actually go backwards for something travelling faster than light. As far as I know, current mainstream science considers actually testing such a hypothesis to be theoretically impossible.

Time slowing down as things approach the speed of light has been tested quite thoroughly, however. Just one result from a very quick google search is right here.

GPS systems have to take at least one, maybe both, branches of relativity into account to give accurate positioning data. If they didn't, all GPS systems would be at least several meters off and might not be very confident about your precise position.
