"Which of these proofs most closely parallels with God's Existence? Why?".
Belief is a form of faith that presents itself in such a fashion that often comes through God. Years ago things such as proofs came about to understand faith better. The argument of the wager, brought about by Saint Anselm, parallels the closest with God's existence. It says that, "If I don't believe and I act accordingly and there is a God, I lose everything. However, if I believe in God and I act accordingly and there isn't God, I lose nothing.".
The argument of the wager makes sense. If one believes in God existence then the person won't miss a step in the path of life. Therefore, one must behave but believe in God and it will parallel with how He feels about his existence. God will not leave anyone out of the Global loop, therefore what Saint Anselm was trying to say was that God will love everyone, but you can't lose if you just believe. .
However, what if there really isn't a God? Does one still lose everything if they have faith and act accordingly? According to Saint Anselm, one won't lose everything if they just believe and there isn't a God.
Never the less, what if one doesn't believe in God? If one doesn't have faith then they lose everything because they didn't have the heart to have a belief in God. Then it wouldn't matter of His existence.
Either way Saint Anselm proved a point that closely relates to God's existence. It is that if one just simply behaves and focuses on their faith in God, then God will have salvation. Otherwise, if God does not exist then the belief doesn't matter and they will lose nothing.
