Replying to the original post.
The Big Bang as taught by evolutionists was supposed to happen in the neighborhood of sixteen to twenty billion years ago. All the matter and energy in the universe was drawn into a ball (the size of a proton, called a "cosmic egg." Violation of conservation of mass and energy by the way.) of energy spinning rapidly.
Firstly: The Big Bang theory is part of astrophysics, not evolution. Secondly, it really doesn't say anything about the nature of the universe prior to the Big Bang. We know that the bang started from a very small area (relatively) and we can speulate on what the universe might have been like at that point, but we really have no idea... and any guess about how the universe got that way, or what it was like before before the big bang is just that: a guess.
Eventually this ball of matter and energy exploded and hurled out particles the size of our Milky Way galaxy and all of the planets, etc.
This is not an accurate depection of the very early universe. Just after the big bang, the energy state in the universe was too high for even atoms to form. The universe was just time-space and energy. It took time for the universe to cool down anough for matter to form.
However, you should ask, where did all this energy for this Big Bang come from, where did the laws of nature come from such as the laws of gravity, centrifugal force, inertia, etc.
"Laws of nature" are simply written down things on "how reality works". So your question is "Why is reality the way reality is". I don't know that there is a "why", and if there is I don't know what it would be. You could ask the same question of God to a theist (why is God the way God is), and likely the answers are the same.
Energy just doesn't "happen," it has to have a source. I always hear "the universe breaks down at a singularity." If you back the universe up 16 billion years it would collapse into a "cosmic egg." What they don't like to discuss is what happened prior to this "singularity" and where the matter and energy came from. The fact is, they don't know and it plain and simply doesn't happen. Of course, they don't know where these laws came from either or how they came into effect, but they believe it happened.
You are correct in the statement "we don't know what the universe was like before it became the universe". It's also true that we don't know where the matter-energy came from. Perhaps it always existed. Perhaps it was created. Perhaps it just popped into being. We don't know anything about the nature of reality outside of the universe, nor the nature of the universe pre-big-bang.
A large problem with your argument is that from "we know nothing" you then assert things you claim are true (you claim to know something). For example, you claim that the energy came into being and that such an act is impossible in extra-universal reality. You don't know either of these to be true.
Since your presuppositions are entirely unestablished, no valid conclusions may be drawn from them.
That is why Evolution is a religion; I think it is a dumb religion. Nobody was there for this "Big Bang" but somehow it happened.
Evolution is a different theory in a different branch of science. Evolution is well proven.
Here is my point. According to the Law of Conservation of Angular Momentum when a spinning object breaks apart in a frictionless environment (such as the Big Bang) ALL the fragments will spin in the same direction.
No. All objects will continue with their current inertia unless influenced by outside objects. The number of assumptions in there (from material consistancy to yoour choice to completely ignore gravity, magnitisim, and dark energy) is rife and problamatic to your position.
However, Venus and Uranus spin BACKWARDS from all the other planets. Uranus actually spins on its side like a wheel. Six of the sixty-three moons in our solar system rotate backwards. Jupiter, Saturn and Neptune all have moons orbiting in BOTH DIRECTIONS. If this problem is solved by saying for example, Uranus getting a "thwack" from an object as I was told by Talk Origins, that creates another problem. Growing a planet by numerous collisions would be largely self-canceling and would produce a planet with no spin at all. This cannot explain why all planets spin. This is yet another problem for those who want to believe that this universe is a big accident.
You now move on to another (non-evolution) topic that again assumes an awful lot about the nature of the solar-system which is unknown.
I'll ignore getting into a detail of how we go from solar nebula to proto-solar-system as you've not complained on that, and we will skip forward to the point where the sun has coeleced, along with most of the planetary disk. At this point, they are all orbiting in the same direction and spinning along with their orbits (there's an interesting gravitational locking that occurs to encourage this).
Why do they spin? As a rotating cloud condenses it gets hotter and spins faster. It's a basic law of physics to maintain the same momentum, if no outside forces are acting which was the case. But now it's called angular momentum, since it's motion of gas (and some dust, it turns out) is more-or-less along circles and not along straight lines. So all that was needed was a big cloud of gas and dust spinning somewhat slowly to give a small fast spinning planet after gravitational condensing. Notice that the planets are nearly spherical in shape, including Earth. Well, as the parts of the big cloud condense and heat up they go into a molten state, making it easy for the internal gravitational forces acting uniformly in each (in a spherical sense) to make a lot of spinning spheres. In physics we say it's a minimum energy state, which nature always strives for.
In many cases the moons form around planets in the same way that the planets formed around the sun... so they too fall into predictable planes and rotations. There are exceptions however.
In the case of Earth's moon, the moon was actually ejected from the Earth's mass by a collossal impact. In other cases, "free-range" objects are trapped by the gravity of a planet. Usually that just spins them off in some odd direction. Sometimes it creates an orbit that eventually collieds with the planet (The Shoemaker_levy comet when it got trapped by Jupiter), and sometimes they end up in a reasonably stable orbit (Earth does have a couple of captured rocks in orbit).
As to Uranus: something hit it pretty hard and tilted it up on its side. It maintained it's original pole and spin, but the orientation relative to the sun moved. Most all planets show some level of deviation from perpendicular, and most all show some level of wobble.
Another problem is when the gases contracted after the Big Bang to form the sun. This would have caused the sun to spin very rapidly. Actually the sun spins very slowly while the planets move very rapidly around it. The sun has over ninety-nine percent of the mass of our solar system while it has only two percent of the angular momentum.
The sun is also less contracted than most (the ice-skater has put her arms out during her spin). In point of fact, the sun does not have a single rotational speed: the core rotates differently than the equater surface which is different from the pole's surface.
But feel free to put up your actual math and we can discuss it.
Why does Saturn have rings?
Gogole has your answer. I don't see enough relevence to type it out for you.
Why is the earth unlike any other planet in the solar system?
Earth is similar to Mars and practically identical to Venus. Unless you are discussing the results of sitting where they do in the solar-system (Mars is arid and cold, venus is a hot-house), in which case your answer includes "because Earth is in a different spot than every other planet".
Most likely if the Big Bang did happen the planets wouldn't spin but yet they all do and at different speeds. Could such an explosion be the source for all these planets, stars, and spiral galaxies spinning in such intricate precision, not very likely at all? The truth is, the Big Bang is a big dud, it didn't happen.
These are simply unspported assertions.
