However you may be forgiven because all teenagers believe they know everything.
There are so many errors and misapprehensions in your brief 'rant' that it is difficult to know where to begin. As Wolfgang Pauli used to say, "it is not even wrong," i.e., it does not even merit being called 'wrong'.
For example:
"One thing that I have thought about is if there was a big bang from one central point, if all matter wasn't incinerated from the start, it would all fly in a different direction from a single starting point. All chunks created by the explosion, however big or small, would go outward in its own way a nothing would come into contact with anything else. This would make galaxies or any clusters of spacial objects impossible to prove."
There was NO matter at the start; only radiation. So 'incinerated' is pretty apt. So, by the way, is "LET THERE BE LIGHT!" Steven Weinberg's book, The First Three Minutes describes a universe made of nothing but radiation--but with densities much greater than granite. No matter could exist. It took thousands of years (millions?) for things to cool sufficiently that atoms could form.
Another error: there was no explosion from a point. The explosion is still going on! Space began expanding.
It is clear that the Universe rapidly reached thermal equilibrium (go take a thermodynamics class) and this has caused problems because there was not time for regions distant from one another to communicate at the light-speed limit. However, a concept called 'inflation' solved that problem; it is possible for spacetime to expand faster than light! This has the effect of nicely homogenizing the early universe, leading to the smooth (but not too smooth) early universe we observe in this epoch.
Do us a favor: get thru college and Astronomy 101 before you give us your take on the nature of It All.
If you want, Radio Astronomer and/or I can give you a reading list.
