> We do all the time. My daughter-in-law is undergoing IVF. The technicians watch the sperm and egg meet and something new begins to exist. Every car that comes off the assembly line is now a car where previously it was not. I do woodworking. I shape pieces and join them, and the object I am making begins to exist as a chair, a chest, or whatever the project is. Two substances join in a chemical reaction, and a new substance is formed that was not there before (salt from sodium and chloride). It is no longer sodium or chloride, but now salt; it has begun to exist.
All these examples are just the rearrangement of pre-existing matter.
No new material is ever created in any of these circumstances.
> You may be thinking of the first law of thermodynamics: Matter can neither be created nor destroyed, but only changed in form.
That deals with conservation of energy, but I'll let that slide.
> In actuality, this is a philosophical statement, not a scientific one.
100% false. The conservation laws (all conservation laws) are direct results of Noether's theorem.
> To be more accurate we'd have to say, "As far as we have observed, the amount of actual energy in the universe remains constant. That is, no one has observed any actual new energy either coming into existence or going out of existence."
Nope. Your ignorance of the basis of the conservation laws doesn't make them less scientific.
I know more about the science than you do. Your proclamations don't reflect the actual scientific understanding (especially since you seem to get most of your scientific understanding from WLC).
> But frankly, the argument wins either way. If the universe IS eternal, then we admit that eternity is possible, and therefore God could be eternal also. If the universe is NOT eternal, it needs a cause.
The argument is that "everything that begins to exist..."
We have no evidence of anything, ever "beginning to exist."
That's the problem with the statement you say things like "this car began to exist" or "this person began to exist" but these are names we place on rearrangements of pre-existing material.
You cannot use these examples to justify "beginning" in an ex-nihilo sense, which is what the Kalam (and you, and WLC) attempt to do.
> Of course it is. But things begin to exist. It would be grossly inaccurate to say that I have existed from eternity because atoms existed. Ah, yes, "I am stardust." No, I'm me. Though I am to some extent the rearrangement of previously existing matter, I began to exist at a particular place and time in my mother's uterus.
"You" is just the name we give to this ever changing collection of matter. You weren't created ex-nihilo.
> The Earth, also, began to exist at a certain time. The fact that cosmic dust existed beforehand doesn't negate that this planet had a beginning with its agglomeration of matter. Before it was not a planet; now it is. We can trace its formation and the causal elements of its beginning.
And none of that was creation ex-nihilo.
Again, you use "begin to exist" in two different ways. It's a deliberate attempt at obfuscation.
> An expansion from what? No one knows. The Big Bang model presupposes that all matter-energy in the universe, space, and time initially began in one point (having zero spatial and zero temporal extension). Space didn't even exist. According to current astrophysics, there was nothing that space expanded into. Space was being created as the universe expands. The universe truly began to exist.
No, not really.
This is a high school level understanding of the big bang.
We know general relativity breaks down under the conditions as t=0. To say that space didn't exist isn't correct.
We can't say what your saying because we don't have a theory of quantum gravity. We don't understand physics at points that close to t=0. You're making claims you can't possibly have scientific knowledge of.
> There is no scientific theory that postulates the existence of matter before the Big Bang. Some theorists propose an infinite density of energy, but with no particular substantiation of that idea.
Here is an article from 15 years ago showing you are wrong:

> I say, by looking at the logic and the science, the Kalam argument has plenty of support, reason, and substantiation.
It has none, since the first premise is a bait and switch and the second isn't scientifically supported.
If you want to exclude creation ex-nihilo, then the Kalam becomes:
1. Everything that begins to exist and is made from pre-existing material, has a cause
2. The universe began to exist and is made from pre-existing material.
3. The universe, made of pre-existing material, has a cause.
Doesn't quite have the same impact, huh?
