proving the proven in real time

While there are plenty factors interfering with the ability to prove something true, time alone is enough by itself to place all proof in question. When you prove something to your satisfaction you are doing it in the present that is soon the past. Most proof soon settles into assumptions very likely true, but which you believe in those moments that are piling up additives placing everything in a different time zone and a different perspective. Things may still appear to be true but it is an operative true for yourself. It is not technically true for all time and for anyone else. In short, time itself and itself by itself is reason enough to rendered absolute truth questionable, meaning nothing can be proved for a certainty. This is only one reason why there are so many lies from even the past which are flourishing factually in the most current present. There are other reasons but ultimately nothing can be proved scientifically.
