Let's take ED's premise which I believe from what he is saying is this:
The universe exists. That is an objective fact. It stands alone. No one other than those that think everything is an illusion will agree. So this is an objective fact that can be used for a multitude of differing theories and beliefs. So we have this universe that we all agree exists, now we must determine what best explains its existence. There are three explanations that we can think of that can contribute to the universe and its existence.
1. It always has existed.
2. It created itself.
3. It was created by something else outside of itself.
1. Science has determined that the universe had a beginning and that nothing existed before it.
Alexander Vilenkin, Cosmologist, says he has convincing evidence in hand: The universe had a distinct beginning though he cant pinpoint the time. After 35 years of looking backward, he says, hes found that before our universe there was nothing, nothing at all, not even time itself.
2. Nothing comes from nothing. How would the universe which didn't exist prior to existing create itself?
3. Number 3 is the only answer that fits with reality and scientific discovery.
If something outside of the universe created the universe, that something had to have certain attributes:
1. Creative power. IF the universe was indeed created it had to be created from something or someone.
2. Had to be eternal. IF not eternal, then there would be a limit to how far back this creative force could go before we are back to the same question.
3. Has to explain how the laws of physics of the universe are the way they are and how they arose themselves.
This evidence supports the existence of God by the claims that the Bible makes for God. That God is eternal and has always existed. HE is an intelligent being that has creative power to create the universe. He is an intelligent being who can make rules that the universe would contain. He has an intelligent mind which could provide a mathematical intelligible universe.
The existence of the universe is evidence that supports God's existence. This is one piece of evidence that supports His existence.
