EWTN Catholic Q&A
Cosmological Argument
Question from Anonymous on 08-22-2012:

How exactly does the Comosmological argument prove the existence of God? Humans do not know how the universe came to be or more specifically, what kicked off the Big Bang. So what evidence specifically points to God as an answer? If His nature is unexplainable by human logic (we can't comprehend something infinite or not having a beginning) than how is He a better answer to the question than simply saying, "we don't know"? If we make an exception for God for not having a beginning, why not cut out the middle man and say the universe unexplainably has no beginning? It makes just as much (or should I say just as little) sense either way.

Dear Anon,

The proof for God's existence is based upon explaining the existence of the world right now. On option is to say that the world today is the result of mindless atoms that have existed eternally and have been bouncing around to produce the world we have today. Although the world today has a certain order (otherwise there could be no sciences) it is all supposed to have come about by chance. That means we are just accidental collections of atoms bouncing around until something bounces us out of existence.That does not seem like a very hopeful explanation of our lives. I suppose we could try to put a meaning in them. But that seems to be quite a task for a collection of atoms that happen to be connected for a while. How much does that make?
