Kalam Cosmilogical Argument

The first premise of this argument is as follows:
1.)Everything that begins to exist has*
a cause.

Does Craig ever answer for matter and energy? Craig says the law of conservation of energy only takes effect once the unviverse is created.*
He says it was created at the big bang. Yet the big bang does not CREATE the universe, it just states that the universe was once very small and then it expanded.*
His saying that the universe must have been created before the law takes effect is wrong for 2 reasons.

1.)the law concerns energy. A big ball of energy (the singularity) would still be effected by laws concerning itself. Why make the assumption that the law only takes effect once this energy isn't a ball, but expanding?
2.)This is a complete assumption in the first place. We have never experienced anything before the big bang, saying that laws can only take affect after it has no basis.

In conclusion:
Can somebody give me an answer as to how matter and energy have causes, though they could not be created?*
They are the basis for everything. Craig sugarcoats his premise by using obvious examples of things being "caused", like chairs and tables.

I understand matter creates energy and energy creates matter, but you have only 2 choices here, either the universe is eternal or one came first.

 

Well this is like the ontological argument Thomas Aquinas presented for God existing. Without going too deep into it he pretty much said God existed because God existed through a number of steps in his proof.

Matter does not create energy and energy does not create matter, they are both states that can be converted interchangeably. The bad thing is that energy to matter is nearly impossible because of the huge amounts of energy it takes to create the tiniest bits of matter. Consider the LHC collider. When the atoms smashes it creates a tiny bit of matter but the matter is also matched by some anti-matter and is destroyed soon after creation.

Concerning the universe, it is possible to show that it isn't eternal because it has at least a lower bound. The energy from the big bang expanded in for a few millionths of a second it was completely plasma and soon it began to 'cool' to form atoms that slowly began to form matter as we know it. Singularities are a tricky subject because it is only known that they are a curvature in spacetime that is infinitely massive and infinitely tiny. It is unknown as to what is inside of a singularity, but according to the Hawking-Penrose theorem it is impossible for particles to inhabit a space that is smaller than their wavelength making it impossible for a singularity to have particles in it.

At least these are my current understandings as to the things you have presented.
