God!

We cannot prove God's existence through philosophy. Philosophy stemmed from science, but that does not give it ability to prove things wrong or right. It is merely a practice by which one can expand their thinking. Unlike science, philosophy theories can rarely be proven.

It is important to use philosophy when considering God, but I don't think that it is the key to solving whether or not God exists. The problem is that God has so many manifestations involving so many different people's opinions. Even if someone is to claim that they saw God, other's opinions on what God is still hold strong. Because of this God's existence cannot be proven.
