The Collapse of the Kalam

I had an epiphany the other day. The epiphany I had was about the Kalam Cosmological Argument which goes.
1. Everything that begins to exist has a cause
2. According the big bang cosmology the universe begin to exist
3. Therefore the universe has a cause
4. Therefore God exist.
If you ever heard or read arguments from Christian Apologist like William Lane Craig they go on to define their god. They normally define their god as a timeless, immaterial, spaceless, personal being of great power and intelligence that created the universe and sustains its existence. I thought about this definition of god with the exception of immaterial, personal being of great power and intelligence, that timeless, spaceless were the conditions that existed before the big bang. My newest epiphany is that the big bang theory with inflation simply means that the universe begin to expand therefore creating space because prior to expansion there was no space, which is define as an interval between objects, and there was no time which is a continuous, measurable quantity in which events occur in a sequence proceeding from the past through the present to the future. 2. An interval separating two points of this quantity; a duration. 2.a system or reference frame in which such intervals are measured or such quantities are calculated. (The American Heritage Science Dictionary) The epiphany is that space-time begin to exist because prior to expansion there was no interval or interaction between two objects because everything was one there wasn’t anything for matter and energy to interact with. I think the energy within the universe has always existed, because according to the First Law of Thermodynamics as as it it commonly called the Law of Conservation of Energy (which includes Matter because from Albert Einstein’s famous formula: E = mc2 mass and energy are equivalent, in other words, all Mass has Energy and all Energy has Mass: in relativity, mass and energy are two forms of the same thing and neither one appear without the other.); from the first law of thermodynamics energy (matter) is neither created nor destroyed it changes from one form to another, and what happen is an infinitesimal amount of matter-energy expanded thereby creating space and time. In other words, the universe did not begin to exist only space and time begin to exist when the existing matter-energy expanded to create space and time. If there was a cause to space and time it was the matter and energy that was already there. Think about it...
