1. Everything that begins to exist has a cause of its existence.
2. The universe began to exist.
3. Therefore, the universe has a cause of its existence.
So....
1. An actual infinite cannot exist.
2. A beginningless series of events is an actual infinite.
3. Therefore, the universe cannot have existed infinitely in the past, as that would be a beginningless series of events.
Since no scientific explanation (in terms of physical laws) can give a real understanding to the origin of the universe then God is an answer. Christian philosopher William Craig fought off science and argued the existence of God and his gift of life to us with the following premise based on Kalam's Argument.
1. The cause of the Big Bang must be uncaused, changeless, timeless, immaterial, and personal.
2. The cause of the Big Bang must be uncaused because there cannot be an infinite regress of causes.
3. The cause of the Big Bang must be changeless and timeless because it created time.
4. The cause of the Big Bang must be immaterial because it created space.
5. The cause of the Big Bang must be personal because how else could a timeless cause give rise to a temporal effect?
Craig also backs up Kalam's argument with this mind-blowing reality: Craig argues that if we had an infinite that had a unlimited amount of members that could neither increase or decrease in number we would have very abnormal consequences. For example imagine a library with an actually infinite number of books. Suppose that the library contains an infinite number of red and black books, so that for every red book there was a black book. It follows that the library contains as many red books as the total collection and as many black books as the total collection (the total collection being the red and black books together). So how many books do you have when you take out all the red books? An infinite amount. How about when you divide the number of books by two? You still have an infinite.This is obviously absurd and according to any modern Mathematics this is contradictory.
I can understand the argument and many of the points that Kalam makes are valid but I still wonder. The premises are full proof and do not leave room for much error, on question they do not answer though is how God came into existence if there is nothing that is infinite. Did he merely just "pop" into the world, and then immediately begin to form it in his own image. This does present something that I can easily believe as true though, and that is that God is infinite. There have been miracles for thousands of years in God's name and though I have not witnessed one I still believe some greater power is behind them and just knowing that they have been going on for ages is proof that God may be everlasting.
