The Big Bang Theory asserts that everything in the universe, i.e.,
matter, force, energy and time, began to appear after a singularity
event.

According to the Laws of Thermodynamics, matter can neither be created
nor destroyed.

How did it happen that matter/force/energy/time, etc. appeared? Where
did it all come from if, for example, matter cannot be created?

I have trouble understanding what seems at first glance to be a
"something-from-nothing" origin of the universe. Isn't this the same
argument creationists use? The "God Created All From Nothing" origin
of the universe? What am I missing?

Cosmologists are at least trying to provide a physical explanation.
Creationists are saying that if we don't have a correct explanation right
now, we must say goddidit and stop doing any research into the subject.

It is important for me to know whether I am very far off in my
understanding of these premise points - because it's obviously causing
me some subsequent confusion. I would appreciate clarification.

(I would like to note that I realize the Big Bang Theory is a *theory*,
however much the evidence so far supports it. I am also curious
whether the Laws of Thermodynamics are adversely affected by
discoveries in Quantum Mechanics - a probable source for more complete
answers.

The Universe is expanding. If we backtrack that expansion, we reach a time
in the past when the Universe was so compact that our current understanding
of physics fails us. Keep in mind that this failure occurs a very tiny
fraction of a second after the origin of the Universe. So if our current
understanding of physics doesn't help us with the moment after the origin of
the Universe, how much less applicable will it be to the conditions that
produced the Universe? Obviously, it's very difficult to study the origin
of the Universe. Cosmologists do have some theories, but how do you study
something that you have no direct access to?
