Does God exist? The cosmological argument

This is a very well-done, helpful and accessible video short by William Lane Craig & Co with Reasonable Faith on the cosmological argument as one clue for the existence of God. While some critique this argument for the many questions it leaves unanswered, we must keep in mind its purpose. This is just one of many clues for God's existence that, together, make a very compelling case that God exists and served as the primary mover of all things at some point in the finite past.
