If by proof you mean scientific proof that satan exists, it is doubtful that you will be able to find proof that either God or satan exists beyond a shadow of doubt.

It is very much like trying to prove from a scientific view point that emotions exist. Indeed, one can see the by-product of happiness or sadness, and the chemical reactions that a human goes through when someone experiences such emotions, but one simply cannot scientifically explain why one gets sad or happy, angry or frightened -- from a scientific point of view. Why does a cuddly puppy bring a smile to someone's face? Why does a stroll down the beach with a loved one give you the warm fuzzies?

To ask someone to [scientifically] prove that God or satan exists is asking the impossible, since both God and satan "operate" in a spiritual realm, and not a scientific one. That said, often the physical, scientific realm and the spiritual realm intersect. The best example of this is when Jesus Christ walked on this earth. Other examples are unexplained phenomena (miracles), and demon possession. When a person starts talking in a language that he or she has never been exposed to or studied, how can you explain that scientifically? There are documented cases where this occurred and some of these cases were attributted to demonic possesion.

Based on what I've been taught, satan is the ruler of this earth, for now. And there is much physical evidence that this is true: war, violence, evil are escalating exponentially.

So how does that jive with the belief that we are constantly evolving and improving? If we are always getting better, then isn't it a contradiction that there is more and more evil in the world? Thus, although it is a "negative proof," I would say the fact that throughout modern history, it can be seen that evil has increased instead of decreased, which is in contraction to how evolution is supposed to work. Thus, there must be some driving force behind this evil, which is satan.
