The Second Law of Thermodynamics: In a closed system [one without external influences] the amount of Entropy [disorder] will always increase with time.
This is an "uncheatable" law. That is it always applies, you cannot get round it, there are no exceptions. It is so well established that some Scientists believe that it determines the "Arrow of Time." That is if you view a video tape of any scientific event, the only way you can tell if you are viewing it forward or backwards is by whether entropy is increasing or decreasing. All other scientific laws work identically both forwards and backwards.
The implications are immense. It means that any order that exists in the Universe absolutely cannot be the result of the passage of time (as some so called scientific theories would have us believe), it must be the result of an external influence. We know there is order in the Universe. We know the Second Law of Thermodynamics to be true. So the only logical conclusion we can come to is that there is a God.
