When an atheist or agnostic will not continue talking with me about the existence of God because I’m using God’s Word in my faith defense, I like to turn to the Cosmological Argument because it deals with something everyone can see – the universe. Atheists and agnostics argue that they don’t believe in anything they cannot see, hear, taste, touch, or smell. They say they believe in the natural only – not the supernatural. The universe is something they can see (light waves) and hear (radio waves). The earth – a part of the universe – is also something they can taste, touch and smell.
