If that is true then all the matter in the universe did come from a point-like sigularity and the big bang theory is true.
This isn't quite correct. First, although Olber's Paradox is a problem for the old Newtonian cosmology, there are all sorts of possible theories to resolve this. One was Fred Hoyle's Steady State Model.
On the other hand, the Big Bang model has been confirmed by all sorts of other measurements (sorry, Fred), and Olber's Paradox is the least of the confirming pieces of evidence for it.
But remember that our current laws of physics do not work at temperatures and densities near the alleged singularity, so who knows what may have been happening during this time -- maybe there wasn't a singularity or an absolute t=0.
It is also unknown how a workable theory of quantum gravity will resolve this issue, as well.

Re: Laws Of Physics..
quote:
1st Law Of Thermodynamics;
This law states that energy cannot be created nor destroyed.
Big Bang does not claim that energy was created or destroyed.
-
quote:
2nd Law of thermodynamics;
This law states that everything is breaking down. (simple Terms)
Big Bang does not violate the 2nd Law of Thermodynamics.
-
quote:
The Conservation of Angular Momentum;
This states that if something is spinning when it explodes, the fragments will be spinning in the same direction. Also angular momentum cannot appear or dissapear.
My lawn sprinkler is initially motionless. When I turn it on, it starts spinning. So, Conservation of Angular Momentum is violated, no?

quote:
Nothingness cannot compact together and decide to explode
Nothing exploded in Big Bang.
-
quote:
There was nothing to trigger this explosion.
There was no explosion.
-
quote:
Total Vaccum does not mean density- the theory states that when the nothingness compacted together, it became very dense. this isnt the case. Total Vaccum is the opposite of total density.
This is Star Trek style gibberish. It means nothing.

Your problem is that you do not know what "Big Bang" is or what it referrs to. This thread has a little more information on what Big Bang really is.
