only problem with that theory is how did the universe all got together in one big ball? and where did all that matter came from?

Not a big ball. A small ball, the diameter of the "ball" was 0.
The basic of the Big bang theory is:
Universum is expanding and going towards more and more disorder (entropy). It mean that if u go back in time the process will go backwards until u reach a point were the entropy (and space) is 0. At that point all energy in the universe is concentrated in this point of singularity. Since u cannot go further back than that its pointless to talk about before big bang. since nothing happen before that time doesnt exist before big bang.
Worth noting is that the theory is not explaining the entire process.
