The best description of uniformitarianism is the present is the key to the past. everything is different today than it was thousands of years ago. what happened yesterday won't happen today. there is no good way to describe uniformitarianism.

The best description of uniformitarianism is the present is the key to the past. People who are proponents of this theory believe that everything, same laws and processes that are happening today, have already happened in the same way, meaning that in the future, the same thing will also happen again. These laws and processes have always operated in the past, are operating now, and will operate in the future. So, we only need to look at the present events to understand what used to happen in the past. 

The best description of uniformitarianism is : The present is the key to the past

Uniformitarianism believe that our current natural condition will always be the same no matter what time it took. so it basically saying that the past is the same with the future
