Ok, you're beginning to understand. Yes the universe as a whole is a closed system and no, neither my shorts nor the shorts of the astrophysics community are in a knot. The universe will eventually be reduced to a maximum-entropy state. The stars are slowly converting hydrogen to helium and increasing the average entropy of the universe. Eventually they will burn out, but I know our star has another 4.5 billion years or so left of hydrogen so don't panic yet.
And remember that the law is that the entropy increases on average. One region can have an apparent reduction in entropy as long as it goes up elsewhere. I already explained this part in my reply to your original question in detail.
I think the problem with space dust that you're having is a real one, although in reverse of what you are saying. After the big bang the universe was nothing but a big cloud of evenly-spaced hydrogen atoms, which actually has a rather low entropy. If the universe had started with all the atoms exactly evenly spaced, the process of transition to lower-energy states (collapse of the gas cloud into stars and planets) couldn't have started! The leading theory on how the great slide towards randomness got started is quantum fluctuations in the primordial gas cloud when it was still small, but who knows? I don't really have a problem with the idea of a God who did it instead because there is no way to thoroughly
test the quantum fluctuation idea.

Oh is that the old "evolution contradicts the second law of thermodynamics" red herring? Well that's been shot down in flames long ago-entropy applies to a closed system which life on this planet is not given the existence of the sun as a continuous energy source. Sunlight continually enters the earth's atmosphere hence entropy does not in any way apply to the evolution of species. Evolution deals only with biology so for the rest of your question you might want to consult a cosmologist or something.

With all due respect, I think you're mixing
apples and oranges.
Creation occurs when energy bits called
"quarks" explode from a stage of energy
we know as "quantum", or "black hole"
energy. There is no time or space connected
with quantum energy.
As quarks explode and form around genetic
frequencies, matter begins to solidify.
Stars show up first because they have the
least amount of resistance. (less electrons
per atom.) Planets take longer because their
atomic structure is more involved.
This whole process is energy interfacing with
Laws Of Physics. It also creates the time and
space. The "Beginning" is really just a point
in a cycle. At this point, there is no cosmic
dust.
Like all forms of creation, the universe runs a
cycle. It explodes, forms, expands and fills in.
Eventually, it collapses and returns to the
state of compression it came from.
Bear two things in mind. Each genetic frequency
is it's own frequency, and formats with it's own
quarks.
And, when all energy comes to a standstill, the
result is one huge "Big Bang."

Entropy ultimately has to do with work being done and things seeking their lowest energy state.
A universe filled with nothing by hydrogen and helium is a high, HIGH energy state. What's the best way to siphon off some of that energy? Fuse hydrogen and helium into denser elements. Ever noticed that fusion stops at iron (excepting, of course, supernova which produce the heavier elements)? This is because the gluon energy of the nucleus of an atom of iron is the lowest state. If you fuse two atoms smaller than iron together, you get a gain of energy -- but fuse two atoms of iron together, and it costs you.
The lowest state of energy was also one which collapsed the hydrogen of the original state via gravitational energy, which ultimately started the process of the first supermassive and short lived stars (which have been observed), which all exploded as supernovae and hypernovae, flooding the universe with a wealth of the heavier elements. The fact trans-iron elements exist on the earth proves that we are in fact remnants of supernovae.
In short, there are no violations of thermodynamic laws that require a deity to explain.

The universe is so completely huge, that the energy required for evolution to happen is not even noticed by the universe. Given all the planets in the universe, and all the energy, it is inevitable that millions of planets will form capable of sustaining life. Given all those planets, it is inevitable that at least some will spontaneously form life. Even if life didn't spontaneously start on earth, it could still be carried here by meteors. Life is inevitable.

Gravity brought matter into clumps after the Big Bang. The electromagnetic force caused nearby atoms and molecules to undergo chemical reactions (in other words, chemistry). Life resulted from various chemical reactions, evolution occurred because of DNA (the genetic code).
Life is really an ongoing chemical reaction. Think about it. If you stop eating and/or stop breathing, chemical reactions stop and cells die. Enough cells die, an organism dies.

Evolution as it is understood and studied only pertains to life on THIS planet.
Our planet is not a closed system. It gets energy from the sun, volcanic reactions, thermal vents, lightning, etc.
The second law does not invalidate evolution.
Second this isn't a religious question. Go to biology and discuss evolution.

Forget about the whole evolution/creation deal. Forget about trying to make evolution into a 'belief' or a layman's 'theory'. Take a look at quantum physics and realize how that messes with people's thought and belief systems (it messed with Einstein's so much that he spent the last years of his life trying to disprove it). If people realized how much quantum physics messed with theology, we'd have a million books and a million 'experts' who would convince the masses that quantum physics is untrue.

Why do people like you think your questions are significant? They just expose the ignorance of the person asking, and that's all.
You're using what couldn't even be called a laymen's understanding of a few natural laws and applying them into situations you don't fully understand, and claiming that that weak and convoluted argument somehow nullifies the mountains of evidence evolution has from various fields of science.
Heck you couldn't even organize your argument that well. Go back to school.

Not a misquote.
Lack of preparation maybe. No wisdom.
Don't think too big.
Big bang = instant order?
This ain't no drive through.
