"Gene" has the only answer that makes the slightest sense in this thread.
The Big Bang may not prove to be correct in the long run, but right now it is looking very, very strong. The reason is that there are a number of independent lines of evidence that all support it. These include:
> It accurately predicts the relative concentration of the light elements (H, He, Li) that we see throughout the universe
> It explains not only the motions of distant galaxies (the red shift), but the change in that motion (the expansion appears to be accelerating).
> It explains, through the inflationary model, why galaxies on opposite ends of the observable universe have similar characteristics.
> It predicts the observed microwave background radiation (the 2.73 K background), as well as -- VERY importantly -- the observed small fluctuations in that background. These eventually formed the "seeds" from which galaxies condensed.
It is important to understand that the observation evidence in each of these cases come from different types of measurement and different lines of inquiry. The fact that they are all consistent with a single model is powerfully suggestive.
Facile answers along the lines of "We can't know" or "God did it" are symptoms of intellectual poverty, not critical thinking. The Big Bang has so far survived astonishingly rigorous observational tests and has made remarkable predictions that were later confirmed by experiment. It may eventually be overturned by something better, but it won't be any time soon.

The Big Bang is a >>theory<< which means it hasn't been proven beyond all doubt to be absolutely true. However, the Big Bang theory is the best one that fits what we know about our universe --
1. All major galactic structures are rushing away from each other.
2. Space is filled with what appears to be the left over heat from the Big Bang, called the Cosmic Microwave Background Radiation.

Let's say that it predicts motions of the galaxies today and also predicted very accurately the concentrations of all the elements we have and had in the early universe..... It's the best we have.

We don't know. It is a theory and is the best answer to the question of how our universe came to be what it is.

It is assumed that the Big Bang didn't actually start the way most people think. It was actually a black hole that is said to have created small asteroids which collided and slowly created what we know today as the universe. Also, many say that it might have been created by the bang of a red dwarf star. Nobody knows.

hard 2 say. since it is just a theory. but it makes sence in the, since we know ( or believe) that the universe is always expanding.

still up for grabs although most scientists believe in it. the red shift is their best evidence

The big bang theory is FALSE.
I mean, what is the chance of asteroids hitting each other, creating the earth???
It couldn't happen.
The earth was created by God.
