Problems with the Big Bang theory starts with about the same questions you do. If after reading it over you have further questions you can try again.
Note that you have your facts about the big bang very wrong. Singh's "The Big Bang" is a reasonably simple book that covers it better than it can be here. It should be in a library near you by now.
You might also try googling to see what you find before you ask people to type up a lot that is already available.
Some aspects of the BB are difficult to wrap your head around so after you've gotten some basics you could ask some clarifying questions. There are a couple of very generous physicists around here that may have time to help.
