Before I answer your questions, let me explain to you why phyicists came up with the big bang theory.
Right now, the observable universe is expanding at an accelerated rate. Why it is accelerating rather than deccelerating is another matter. So, physicist tried to see backward in time by making the model of the universe going backward from where they are going now. This simulation ends up with the entire visible universe going back to a single point. Of course, that is the easy way of saying it. Behind that is a lot of math, which I'm not at the level to fully understand all of it yet.
Anyway, that is why they proposed the big bang model of creation. You have to understand something about the big bang model that most people don't pay attention to. When everything exploded, it wasn't just mass and energy that expanded. Space-time itself also expanded to almost the size of the visible universe today in 10^-100th of a second. That's .00000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000001 second. Again, in order to make sense of all the data people have gathered so far, they had to make the big bang model that way, with space-time expanding like that, in order for the data to fit together. Everything there is purely theoretical.
Another thing I want to go over is the string theory, because I can't really explain anything without touching on the string theory.
We know that everything that has mass is made of atoms, which can be broken down to subatomic particles like electrons and protons, which can be broken down to quarks, which can be further broken down to ups and downs, etc... So, does matter keep breaking up to smaller and smaller parts, or does it finally end somewhere if you break things down small enough?
The string theory proposes that matter DOES break down to a unit where it can't be broken down any further. This infinitesimal unit is like a rubber band looking shape that vibrates. Now, the frequencies of vibration actually tell us what the particular matter is, say a gold atom or a hydrogen atom.
When you vibrate a string on a 2 dimensional plane, you only get a certain number of possibilities for the frequencies of vibration. If you add in a 3rd dimension, then you get more possibilities for the vibrations. This is all math by the way. If you put everything we know about the universe into account, you need to put 10 dimensions in the equations in order for the string theory to hold and the universe to exist like we know it today. Again, this is lots and lots and lots of mathematics, not just speculations.
Therefore, mathematicians and physicists concluded that the universe that we live in actually have 10 dimensions rather than 4, like Einstein proposed.
Ok, 1-D is a dot, 2-D is a plane, 3-D is space, and 4-D is space-time. That is the limit of our perception of the universe. What the heck do the other 6 dimensions look like???
Now, onto your questions.

so, at first there was nothing in the universe, exept for a very small amount of dust or dirt or some matter, and for some reason it all came to one piont in the universe, first question, y?
This aint the big bang theory at all. I don't know where you got this from.
quote:
and was a little smaller than a "." on this page, and for some reason it started to spin at a high rate of speed, second question, y?
Scientists hope to find out one day why this little point of space-time exploded into the universe we know today by figuring out what the other 6 dimensions look like. Trust me, we will be able to answer a lot of questions if we ever discover what the 6 missing dimensions look like.
quote:
and from a very small spec of dust came HUGE planets, the entire solar system, and moons, and stars, and the sun wich is to my understanding not much diferent from a star, how did a speck of dust create all that?
Again, this ain't an accepted version of the big bang theory.
The big bang theory said that all the matter in the universe was contained within this little point of space-time. Then, it exploded, releasing all the energy and matter of the universe into a 4 dimensional space that we know today.
If you are wondering how everything in the universe was condensed in a little dot, take some physics classes or read some books. I can't really explain it on here... or I supposed I could try... but that's for later.
